New Study DESTROYS Creatine (is it really worthless?)

Summary

A recent study has sparked debate over the effectiveness of creatine. Dr. Mike from RP Strength discusses a study showing creatine doesn't enhance muscle gain when paired with weight training. The study, involving 63 participants, suggested increased lean mass due to water retention rather than muscle growth. While this finding contradicts numerous prior studies, Dr. Mike emphasizes the importance of considering the entire body of scientific evidence, suggesting creatine does promote muscle growth, albeit at varied effectiveness across individuals.

Highlights

• Dr. Mike discusses a study showing creatine's mass gain is primarily water, not muscle. 💧
• The study involved 63 participants over 12 weeks, but no major muscle differences were noted between creatine and non-creatine users. 🤔
• Previous research consistently finds creatine enhances muscle growth beyond just water retention. 👫
• Dr. Mike likens understanding scientific results to gathering multiple opinions; one study is not definitive. 🧐
• The cumulative evidence shows creatine aids muscle gain, making it a reliable supplement. 🏋️

Key Takeaways

• A new study claims creatine does not aid in muscle gain when paired with weight training, attributing weight gain to water retention. 💧
• The study's findings contradict numerous prior studies that show creatine as effective in enhancing muscle growth alongside resistance training. 🏋️
• Dr. Mike urges caution, stating that isolated studies should not dictate conclusions; the wider body of evidence still supports creatine's benefits. 🔍
• Despite this study's findings, creatine remains one of the few supplements empirically shown to aid hypertrophy. 📈
• Creatine doesn't bring steroid-level results but can still offer noticeable benefits over time. ⏳

Overview

In the latest RP Strength video, Dr. Mike dives into a new study challenging the long-held belief in the muscle-building prowess of creatine. The study conducted over 12 weeks with 63 participants suggested that the lean mass gained from creatine was primarily due to water weight, casting doubt on its muscle-enhancing reputation. As Dr. Mike unravels the study, he compares its methodology and findings with the broader spectrum of research on creatine.

Dr. Mike explains that while this study provides an interesting perspective, it stands in contrast to decades of research showing creatine's effectiveness in muscle hypertrophy. By reviewing prior studies, he highlights how creatine has consistently demonstrated muscle growth benefits, albeit modestly compared to other factors like diet and training. He stresses the value of considering a wide range of studies before concluding creatine's effectiveness or lack thereof.

Despite this study's assertions, creatine remains a go-to supplement for those seeking support in their muscle growth journey. Dr. Mike concludes that while creatine might not transform bodies overnight, it reliably supports muscle gain, and with further research, we might refine our understanding of its role. Whether a heavy lifter or casual gym-goer, creatine continues to be a staple in the fitness supplement world.

Chapters

• 00:00 - 01:00: Introduction and Study Overview In this chapter, Dr. Mike from RP Strength discusses a recent study about the effectiveness of creatine when used in conjunction with weight training. The study suggests that creatine does not significantly contribute to muscle gain beyond the water retention it causes within cells. Dr. Mike plans to examine the study in detail, including its methods, results, and conclusions.
• 01:00 - 02:00: Study Methodology This chapter discusses a new study on creatine, where both males and females participated in a 12-week training program while consuming 5g of creatine daily. The study measured muscle size before and after the period. The chapter emphasizes comparing this study to previous research to ascertain the truth about creatine's effects. Additional references and details from the study are provided for further reading.
• 02:00 - 03:00: Results and Initial Reactions This chapter provides an initial reaction to a study conducted primarily by researchers from the University of New South Wales in Sydney, Australia. The study is praised for its robust design, strong internal validity, and the importance of its insights. The chapter promises to delve into the basic design and findings of the study before exploring further details. It highlights the positive regard for the study's quality while hinting at potential concerns with the name of the university being sensitive for public platforms like YouTube.
• 03:00 - 04:00: Detailed Analysis of Study Findings This chapter focuses on analyzing the findings from a study that investigated the effects of creatine monohydrate, alone and in conjunction with resistance training, on lean body mass. The study involved 63 healthy adults, comprising 34 females and 29 males, with an average age of 31 years. The primary aim was to determine if creatine monohydrate increases lean body mass beyond mere water retention. The study is highly relevant in the fields of exercise and sport science due to its substantial sample size.
• 04:00 - 05:00: Comparison with Other Studies This chapter discusses a study conducted as a randomized control trial, which is known for its rigorous methodology. The study involved 63 participants divided into groups that either received a daily supplement of five grams of creatine or a placebo over a period of 13 weeks. The sample size, though not very large, is considered sufficient to yield significant insights. The chapter emphasizes the clarity and depth of understanding achievable from this sample size.
• 05:00 - 06:00: Science of Muscle Gain and Study Reliability In this chapter, the focus is on a scientific study examining the effects of creatine supplementation on muscle gain. Participants consumed either fake or real creatine at a dosage of 5 grams per day over a 12-week training program. Lean body mass was measured at three points: the start of the study, after one week following the creatine loading phase, and at the end of the 12 weeks. Dual-energy X-ray absorptiometry (DEXA) was used to measure muscle gain, highlighting its accuracy and reliability.
• 06:00 - 07:00: Creatine and Muscle Growth Evidence This chapter discusses a study on the effects of creatine on muscle growth. Participants undergo a 13-week trial, starting with a week of either creatine or placebo intake, followed by 12 weeks of resistance training. The results show that after the initial 7 days, those who consumed creatine gained approximately one pound more muscle compared to the control group. However, these findings mainly suggest an increase in water retention rather than muscle mass.
• 07:00 - 08:00: Mechanisms Behind Muscle Growth with Creatine This chapter investigates the effectiveness of creatine on muscle growth, specifically examining whether creatine supplementation in conjunction with weight training leads to more muscle gain compared to weight training alone. Initially, creatine's effect of drawing water into cells is observed. The expectation is that those who weight train while taking creatine will show more significant muscle gains between week one and week 12 compared to a baseline without creatine supplementation.
• 08:00 - 09:00: Conclusions on Creatine's Efficacy In this chapter, the results of a study on the efficacy of creatine supplementation in muscle gain are discussed. Both the creatine and non-creatine groups gained approximately 4 lbs of lean mass over a 12-week training period. However, there was no significant difference in muscle gain between the two groups, suggesting that creatine supplementation did not provide an additional muscle growth benefit in this context. This finding raises questions about the effectiveness of creatine in enhancing muscle growth.
• 09:00 - 10:00: Practical Takeaways and Future Research Directions This chapter discusses the effects of creatine supplementation on lean mass increase between males and females. The study indicates that females may experience a slightly larger increase in lean mass due to creatine compared to males. This could be attributed to the fact that females often consume less protein and meat. However, the increase is marginal, and neither gender showed a significant increase in lean mass overall. The chapter concludes with practical takeaways and suggests future research directions to further explore these findings.
• 10:00 - 11:00: End Notes and Closing Remarks The chapter discusses the effects of creatine on muscle gain as observed in a study conducted over 12 weeks. It was found that people who consumed creatine experienced an initial increase in lean mass, which was primarily attributed to water retention rather than actual muscle growth. The study concluded that taking 5 g of creatine per day did not significantly enhance muscle gain beyond the initial water retention phase, and those who used creatine for weight lifting did not gain more muscle than those who did not use it.

• 00:00 - 00:30 hey folks Dr mike here for RP Strength and today we're going to talk about a new study that came out that shows that creatine is not effective when combined with weight training to actually get you more jacked and that all of the quote unquote muscle or lean body mass that you gain from creatine seems to come only from the water that creatine brings in with it into the cell uh-oh is creatine in trouble well let's find out let's talk about the study break it down figure out the methods the results talk about what the conclusions are and then
• 00:30 - 01:00 compare it to the other studies that have been done about the subject to see where the truth really lies so new study came out about creatine people males and females trained for 12 weeks took 5 g of creatine daily this was a great study measured muscle size pre and post i'll link the study in the description and a bunch of references as well too if you want to read up to some of the other studies we'll be talking about today and
• 01:00 - 01:30 this is a really good study so we're not dogging on the studies is seriously good work by the researchers mostly from um University of New South Wales in Sydney Australia om word to say that starts with a C and ends with a n that they say in Australia YouTube will kabash us for that one great study design very robust internal validity and has important insights so let's take a look at the uh basic design and findings before digging a little bit further so the purpose of the study the
• 01:30 - 02:00 express purpose was to examine whether creatine monohydrate which is the most common and the most effective form of creatine alone or combined with resistance training increases lean body mass beyond just water retention the participants were 63 healthy adults 34 females 29 males with an average age of 31 years very applicable i mean this is a big study in exercise science and sport science 63 healthy adults is one
• 02:00 - 02:30 hell of a sample size we're going to be able to conclude a lot of really good stuff from such a massive sample size the clarity with which we can see the world with 63 participants is very very high it was a randomized control trial which is probably the most rigorous kind of study that there is they compared five grams of creatine supplementation per day with no supplementation over 13 total weeks that means each group got fake creatine or real creatine did a week of
• 02:30 - 03:00 consuming the fake creatine 5 g per day or real creatine for 5 g per day 12 weeks of training and got their lean body mass measured at the beginning after one week after the creatine loading phase was concluded and at the end of that 12week phase so the measurement method to figure out how much muscle they were gaining was via DEXA which is really really really uh insightful method and also by um well no
• 03:00 - 03:30 I guess yep just dexa yeah at baseline after the washin period which is a week of taking creatine or fake creatine and after that 12 weeks of resistance training which is 13 weeks total the first week is just to get the creatine going they found that the immediate effects after 7 days of of consuming creatine was that the people that consumed creatine on average gained about a pound more muscle quote unquote than the control group that didn't have creatine and that mainly indicates water
• 03:30 - 04:00 related changes because creatine does not grow a pound of muscle if you just start taking it that's creatine bringing water into your cells so far so good very very expected what we would expect next if creatine really is effective at helping you build muscle is the group that weight trained with creatine would gain more muscle between week one and week 12 versus between week zero and week 12 than the group that weight trained but didn't have any creatine the resistance training phase
• 04:00 - 04:30 occurred both the uh groups the creatine and non-creatine group gained roughly 4 lbs of lean mass which is pretty dope for 12 weeks of training and there was no significant difference between groups uh-oh that means that the group that took creatine and trained didn't gain any more muscle than the group that didn't take creatine and trained that is curious if creatine actually affected muscle growth you would think it would
• 04:30 - 05:00 boost training results but in this study it did not females had a little bit of a bigger lean mass increase from the creatine washin a lot of times females actually respond a little bit better to creatine because females typically tend to undereat u protein and undereat meat compared to males sometimes they have a bigger response in some studies to creatine such a small amount that I wouldn't say this is something to run home to but um neither sex showed significant lean mass
• 05:00 - 05:30 gains over the course of the 12 weeks of training if they took creatine versus if they didn't not great so the conclusion of the study by the study authors was that creatine's initial lean mass increase is almost certainly likely due to water retention that's not contentious and that creatine in this study did not enhance muscle gain beyond its initial water bloating effect so that the people who used creatine to help them lift weights didn't get any more jacked taking in 5 g of creatine per day which
• 05:30 - 06:00 is the standard dose is the dose I take than the folks that didn't and the author's implication here was that maybe a higher creatine maintenance dose that during the 12 weeks more than 5 grams a day might be necessary for creatine to show additional true hypertrophy but this is kind of an interesting conclusion to me most studies show that five grams is more than good enough many studies show that two to three grams of creatine can detectably enhance muscle hypertrophy so what the hell is going on here right um so we have to be open-minded and think okay maybe the
• 06:00 - 06:30 muscle quote unquote that people gain on creatine when they think they're gaining is really just body water and some of it definitely is but this study just by itself concludes that all of it is and for this study that's definitely true that's what seemed to have been happening but before we conclude this video and say hey listen creatine has been refuted i'm sure you've seen a bunch of memes and infographics by now that no creatine doesn't work science works never ever ever one study at a
• 06:30 - 07:00 time science builds its understanding of the world by taking lots and lots of studies and putting them together zooming out and seeing you know what is the overall message we're getting from these studies let me give you an example in the real world with almost no science whatsoever let's say you have a friend that you think is super funny and super cool and you have another friend that you think is super awkward and kind of weird you love him but it's not for
• 07:00 - 07:30 public consumption maybe you are biased you're just vibing weird maybe you're the weird one and the friend that you think is cool and funny really isn't and the friend that you think is awkward and strange really isn't and they're roughly kind of the same effect on people that they meet if I gave you a situation where we had both friends separately meet with a person who never saw them before and then afterwards we asked the person hey which one was funny/cool and which one was kind of weird
• 07:30 - 08:00 whatever that one person says how much faith do we put in to their answer being like the actual truth that pretty much everyone will agree with come on one person i mean the person you pick could just be a wacky strange no offense Dungeons and Dragons playing Asmouth and then they'll be like "I really like the weird friend he was the cool one to me." And you're like "Oh that's not true that's wrong." What if you had someone who's a real bro and real like vibes
• 08:00 - 08:30 person they like the chill cool guy and they hate the real nerd guy but maybe that's not representative not everyone's a bro so how do you really parse that problem that right there is one study at a time how do you really solve that problem over time you have 100 people at least 10 people for the love of God meet your two friends and tell you afterwards hey which one was cool and which one was weird look if you meet a hundred people and most of them say you're chill and funny you're probably chill and funny if
• 08:30 - 09:00 you meet a 100 people and most of them say you're kind of weird you're probably kind of weird but it's those multiple interactions that really build a big picture one examination at a time could just be chance it could be mismeasurement it could be that the person you're asking hey how was my friend they're actually thinking about their exam they have later that day and they're like "Uh yeah that one was chill he was funny it was cool yeah I got to go." and you're like "Okay I guess that's what it is." It's like "They didn't even think it through that's just error." So that's how science works so if you see anyone study at a time we
• 09:00 - 09:30 can't be too sure that they really discover the truth or that it was just strange finding statistical error is 100% possible our understanding our visibility to reality is fuzzy but if we do it over and over and over and over then after a while we're like "Yeah man that really is a thing." Another quick analogy is one of sports you have two people who play basketball how do you find out who's better at basketball do you have them play one game um I mean people get lucky the guy can sprain his
• 09:30 - 10:00 ankle a guy can have an off day one game doesn't tell you a lot but if you have people play 10 games against each other 10 games to seven points or something like that and one guy wins eight games and loses two he's probably the better basketball player so what we're going to do now is we're going to look at a huge body of evidence kind of a total body of the evidence we've collected over literally decades about about creatine to ask two questions about creatine to see if they agree or disagree with this
• 10:00 - 10:30 study here are two questions does creatine cause actual muscle gain and not just lean not just uh body water gain we test this we do after wash out period so they have people train with weights and either take creatine or not and then they don't test their lean muscle after the study they test it a week later when they're no longer taking creatine so they lose all the creatine bloat and if that group still has more muscle gain than the group that didn't take creatine well it must have been something the creatine did cuz that was the only different variable and the body
• 10:30 - 11:00 water isn't even around anymore so then creatine really actually caused muscle gain the second thing we're going to look at is whether creatine enhances that weight training induced muscle growth in a way that's independent of water retention which is really kind of the same thing but we need to see does the wash out period account for that and then later okay now we have the wash out period it really works does the creatine enhance weight training performance and muscle growth in a way that is reliable and happens with or without the creatine
• 11:00 - 11:30 present so took a look at a bunch of studies i've summarized or I've linked some of them for you in the description of this video if you want to take a look couple of findings that are very very apparent through these studies first creatine alone with no resistance training if you take it it primarily increases your lean mass due to intracellular water retention and typically you get like basically two
• 11:30 - 12:00 pounds of rapid lean muscle lean body gains within about a week of taking creatine at even 5 grams a day and that's very little if not zero actual muscle growth it's just body water so that's true bloat which also means that if you take creatine all the time and you don't lift weights which would be strange to do you're not going to get jacked now that's not the case for all supplements and drugs if you take anabolic steroids and you don't lift weights you actually just grow muscle even without
• 12:00 - 12:30 weightlifting which is triple but with creatine that doesn't seem to happen but it does cause a body water increase you take creatine for a week your body mass goes up lean body mass your muscles look more swole literally in the mirror and you don't take creatine for the week and it goes right back down make sense now creatine so that's answering our first question there is absolutely this effect creatine combined with resistance training does it actually gain you
• 12:30 - 13:00 muscle aside from body water a lot of findings here first we find in multiple studies that creatine consistently enhances true muscle hypertrophy beyond water typically the group that used creatine versus the one that didn't adds about 2 to four pounds of muscle more than the group that doesn't which is really really dope over the course of about 8 to 12 weeks by the way so
• 13:00 - 13:30 roughly 10 weeks of weight training and taking creatine you can expect maybe about three extra pounds of muscle gain that's the first time you try creatine it levels off after that but that's pretty impressive and you see greater increases in muscle fiber cross-sectional area confirmed via muscle biopsies confirmed by MRI and ultrasound and some of these methods do account for body water which is really really dope we've had creatine studies that have looked at fiber specific
• 13:30 - 14:00 hypertrophy we find that type one fibers and type two fibers type two fibers a little bit more are are experiencing muscle hypertrophy increase which is really awesome we can also examine regional hypertrophy creatine isn't just a whole body effect some studies assess the muscles that were trained versus just a random muscles in the body so you you have a person who's lifting for just their arms and their arms while taking creatine grow way way more uh in this case 7.1%
• 14:00 - 14:30 gain in muscle cross-sectional area versus 1.6% gain without creatine that is very impressive very impressive and not accounted for by body water so this indicates true hypertrophy is linked directly to exercise stimulus in addition to taking creatine and another study or group of studies finds that older adults also experience meaningful hypertrophy and so that starts to say that not only are they experiencing meaningful hypertrophy but there are
• 14:30 - 15:00 functional improvements associated with creatine muscle gain what does that mean that means in most of the studies that test not just your muscle gain from creatine which could be body water but they test your strength as well and in almost every study when you gain muscle from creatine you also get stronger just adding body water to a muscle bloat it up it gives you a pump doesn't make you stronger only adding actual physical muscle like the the myosin and actin
• 15:00 - 15:30 machinery in the sarcimeirs that makes your muscles contract to do the thing that's the only thing that's going to make you stronger outside of neural changes and remember the groups that don't use creatine they get the same neural changes cuz they're doing the exercises so the nervous system gets the same workout either way the creatine group not only do they get bigger they get stronger too now that shows us that man there's something happening here that is not accounted for by body water alone and a couple of studies actually multiple studies focused on the idea of
• 15:30 - 16:00 like well what if we're just not washing out properly an example here is one specific study canow at all which should be linked in the description I sure hope um they did a wash out period where they gained they so they basically did some training with creatine then they did a bunch of training without creatine and their gains from the creatine training phase still held in place weeks after the creatine was no longer around and that
• 16:00 - 16:30 confirms that the hypertrophy or very highly suggests that the muscle growth folks got from creatine really was actual muscle because the body water is gone but you're still more jacked kind of by definition means it can't be body water now a similar study that was just done which is the study we're reviewing this Hagstrom paper it showed that well actually after wash out period we don't have any sort of uh effect there the washin period uh accounted for that and so we basically saying here that well it
• 16:30 - 17:00 was really only body water now it could be true except we have one study that shows creatine only results in body water gain which is this one and there's a few more out there floating around and then literally dozens of studies just as well controlled that show that creatine enhances actual muscularity in addition to bringing in body water one study at a time when it is an aberrant conclusion that doesn't align with most of the other studies is very interesting but if you look at most of the studies at the
• 17:00 - 17:30 same time which is what science is all about it's starting to show us that creatine probably actually makes you jacked every now and again some studies get wacky and they find no effect but I'll get to why they're doing that in just a little bit so for now our confidence in creatine is starting to rise significantly more than when I first started this video and told you "Hey mate creatine this new study found doesn't really do anything." Here's another interesting line of evidence that shows us creatine probably gains muscle i mean the best evidence is directly shown to gain muscle uh
• 17:30 - 18:00 irrespective of body water gain that's the most direct but it's really cool to also have indirect evidence to support that position so we have a bunch of it first creatine usually enhances the performance you get more reps per set or able to do a little bit more weight per set and it enhances your ability to do multiple sets productively for higher reps every time and it enhances your relative effort it enhances sorry it enhances the result of your relative effort the performance in each set and it enhances how much volume how many
• 18:00 - 18:30 sets you can do productively before you get so weak that you can't really train anymore that we know getting more reps per set and we know that doing more sets productively robustly predictably causes muscle gain because creatine is allowing us to do that we're saying well there's this mechanism by which we know weight training re leads to more muscle and creatine is clearly doing it okay that's pretty cool but wait there's more in
• 18:30 - 19:00 multiple studies cell swelling especially certain kinds of cell swelling triggers anabolic signaling a swollen cell becomes more likely to grow muscle and the initial water-driven intracellular expansion of creatine seems to cause muscle protein synthesis pathways to activate this has been confirmed in numerous studies cell hydration especially if you're dehydrated cells is a known anabolic stimulus is it really reliable is it really dependable does it really cause a lot of growth no do nitric oxide
• 19:00 - 19:30 supplements help you get a pump yeah but that's actually your blood vessels expanding and not your muscles expanding so unfortunately taking nitric oxide pump supplements gives you cooler pumps but it's mostly a blood flow thing and not an intramuscular selling cell swelling thing but if your cells swell from either resistance training maybe even from creatine consumption and definitely from shooting exogenous insulin and growth hormone but I get ahead of myself there don't do that at home it's probably causing at least a mild mechanistic increase in muscle
• 19:30 - 20:00 growth okay another indirect data point that's very good here's where the real shit is hitting multiple studies confirmed including randomized control trials that creatine significantly increases muscle fiber nuclei number that means that satellite cells donate their nuclei to the main cells and that is one of the most powerful and predictive mechanisms of boosting hypertrophy it's a different thing if
• 20:00 - 20:30 you take creatine and dot dot dot something happens and then maybe you look bigger versus if you take creatine and instrumentation confirms that it's activating the most powerful growth pathways that the body has that means it's probably growing some muscle now some things activate pathways but the pathways end up getting muted later or deactivate some and on the net balance it doesn't grow any muscle but remember from earlier from most of the studies we already know creatine grows muscle from some of those studies we know that creatine grows muscle even if we account for the body
• 20:30 - 21:00 water effect from other studies we know that it boosts the ability of training to drive a stimulus that's really good and now we're seeing that well it activates satellite cells more and brings in more myionuclei which is a known from 50 other different kinds of studies way to get you more jacked here's the last one for this part creatine reduces myostatin expression myostatin muscle stopper is a protein everyone makes in their skeletal muscles that reduces how much muscle growth you
• 21:00 - 21:30 have it's a cap on your growth if you make less myostatin it frees your muscles up to grow more you guys ever see those pictures scott can we insert a picture of one of those greyhounds or cows or some shit like that that has broken myostatin yes those animals just have a completely non-functional skeletal muscle meostatin gene which means they grow muscle doing nothing all the time and they grow maximum muscle all the time this shit is way more powerful than steroids creatine just by a little bit has been shown in the
• 21:30 - 22:00 scientific literature to decrease the expression of myostatin which means that protein that blocks growth creatine lowers it it frees up more growth now man this is starting to look like we have evidence of creatine gaining muscle we have evidence of that in the absence of body water or controlling for body water changes we have performance enhancements we know also cause hypertrophy creatine does those and we have satellite cells and myostatin activity being modulated both of which
• 22:00 - 22:30 are really linked to growth it's kind of starting to look like something's happening you know it's like you see a guy in an expensive car and you're like is he really rich he shows you his bank account you're like "Okay that's a lot of money but is it fake?" He shows you his portfolio of companies and you're like "Okay these clearly make money." And then you're like "Well maybe it's all fake." You talk to the customers and they're like "These are great products and I pay money for them all the time and they really work." And you're like "Yeah guess this guy really does make money holy crap." Multiple a consilience of evidence from multiple perspectives
• 22:30 - 23:00 shows you yeah this thing is probably really happening so what are the conclusions from this overarching body of evidence creatine reliably augments improves real muscle hypertrophy with resistance training these effects extend beyond acute fluid shifts and they are sustained after supplementation the muscle you build on creatine most of it you keep afterwards that's cool
• 23:00 - 23:30 and maybe a higher initial loading phase or more sustained high dose clearly enhances hypertrophy but we know for many of these studies that even lower doses do this in most of the studies some of the studies that show creatine doesn't work and this study we reviewed today is not one of them are too short-term just a few weeks or too low dose one to two grams they show that creatine doesn't build muscle but that's really like you know asking someone like hey um interact with my friend to see if he's funny they're like okay they sit across the table they're like "So what's
• 23:30 - 24:00 up?" And the friend's like "So anyway," and they're like "Okay that's it what do you think what is he funny?" Like "But I didn't even hear him saying I I don't know his face looked I don't know not enough not enough time not enough friend." You get the idea overall practical takeaway from this whole body of literature is that creatine results in actual muscle gains function to make you bigger and stronger are really supported by mechanisms and are irrespective of body water though it does also help with the body water thing it's not just transient body weight like
• 24:00 - 24:30 this study found and in fact creatine is one of the few genuinely hypertrophic supplements robustly backed by randomized control trials there are not a lot of other supplements that have the effect creatine does creatine is the number one non-drug muscle building supplement period especially if you're consuming enough protein in your diet so what does this mean about our new study here's the thing like I said earlier one study at a time means very little if not
• 24:30 - 25:00 nothing at all in the grand scheme imagine you're trying to figure out Scott we go through this all the time right when we're collabing with people and we start talking about other influencers with them and we're asking them like "Hey is XYZ person cool and they either say yes or no how much stock do we put into one person's opinion?" Yeah very little you got to pull some more you got to pull some more man you don't know they just didn't vibe right or something like that one study at a time just says almost nothing which you guys can take into the real world if you
• 25:00 - 25:30 follow Instagram some of these science pages you go on the news or your aunt at Thanksgiving tells you well I heard a study says a study is a hint it's a hint the rest of it is like all the studies combined that's how you really find out so far creatine is one of the most well- vetted supplements and actually builds muscle for multiple multiple studies not just water weight but here's the thing creatine does not build a ton of muscle it is not like
• 25:30 - 26:00 weight training it is not like steroids and it's not like eating a good diet high in protein getting lots of sleep it's a much smaller effect than that and it takes months to pack on enough muscle for you to really notice so some studies because of this very low effect magnitude of creatine just by chance through statistical noise even though creatine is under the hood actually effective some studies will find that it's not effective simply because it has such a small effect if your friend is the funniest person of all time a
• 26:00 - 26:30 5minute conversation with most people revealed to them that okay at least he's really funny if your friend is really low-key funny Scott you ever have people be like "My friend is hilarious." And then you meet them once and you're like "H yeah all the time." And all the time and then you but you hang out with him a few more times and you're like I I get it i get it but you have to like know who Jim is you know he's subtly funny in his own way you know what I'm talking about absolutely but it's nothing you would immediately like just see and so
• 26:30 - 27:00 only with tombs can we see immediately that the person is not like the other right so basically if your friend is low-key funny a lot of people interacting once won't pick up on that and be like "This that's not funny." But you're like "Trust me you get to know him he's really funny." Well that's multiple samples so every now and again a study about creatine will conclude that it doesn't do anything simply because it just doesn't do a whole lot if creatine did a ton almost every study would find something but creatine doesn't do a ton and a good way to illustrate this is that the effect of creatine is on on
• 27:00 - 27:30 lean muscle gain is sometimes like comparable or even smaller than the error in measurement for example in this study the you know the one pound of body water and muscle um that the folks gained in the washin period if you read the actual study the variance plus minus on average was uh three pounds the noise is three times bigger than the signal are there ways to parse that over
• 27:30 - 28:00 long enough durations yes but is there a probability you'll miss the whole thing yeah hell yeah there is so here's the kind of end-of-the-line recommendation I have yes creatine still works yes you should still be taking it on the other hand you should always be on the lookout for new research that will finally tune exactly how strong creatine is because it could be like over in the next several years we find
• 28:00 - 28:30 that you know what creatine is actually underrated and if you take it like this or combine it with this kind of training is actually more powerful than we thought we might find that creatine is accurately rated or we might find that actually creatine a little bit overrated it does grow some muscle but not as much as we used to think before because there was kind of a file drawer effect of selection bias in the studies the more studies we get the more unbiased they are the more that creatine sees it does have an effect but a very small one um and one of the reasons I'm telling you guys this is creatine doesn't have these crazy transformative effects it works it
• 28:30 - 29:00 helps but it's not this steroid like effect so don't plan on when you start taking creatine to be like "Dude taking creatine now don't with me i'm going to be huge." If you're looking for steroid effects from creatine you're almost always going to be disappointed another thing is there's a variance within individuals of how they respond to creatine some people hardly respond at all or not at all some people respond a ton some people who have very fast twitch muscle fibers and a lot of them you know have undereaten meat significantly which has its own little
• 29:00 - 29:30 creatine in it they'll get huge gains some people like after 3 months of training gain 7 lbs of muscle from creatine addition very rare but possible i knew at least one person that did that reliably the thing is this study they could have just accidentally recruited mostly creatine low or non-responders and that's why they found the situation they did but for almost everyone taking creatine don't expect for the steroid like effects and at worst you'll be pleasantly surprised uh at best you'll be pleasantly surprised at worst you'll be like I gained a little bit and that's
• 29:30 - 30:00 cool that's exactly what I was expecting all right folks that's all I have for today hopefully that makes sense got some references in there for you to read up if you're a super nerd and in the description and I will see you next time [Music] [Applause]
