A lot of people keep making the straw-man argument, stating that taking BCAA's without regular protein would be ineffective. That would be stupid, and no one has ever argued that. The purpose of BCAA's are to put the body into an anabolic state, to stimulate protein synthesis and build more muscle. It's common knowledge that taking free-form amino acids have very different effects than just eating protein that includes it. If people only needed regular protein, why would anyone take ANY other supplement such as creatine or even steroids?

[@Michael-Archonaeus]

That last one is mainly popular, because it makes people feel ticklish or itchy, which they interpret as it actually having an effect on their performance. I have personally found that substituting my pre-workout supplement with beta-alanine for a simple caffeine pill before my weight training seems to give me the same performance enhancing effect, but without the itching, so currently I am using up my remaining pre-workout supplement, and then planning to stop taking pre-workout supplements; it's not just the itching from the beta-alanine, it's some of the other ingredients that I feel uneasy about, such as the artificial sweeteners they use. In fact this is something that is bothering me in general, all the cheap protein powders and gainers use sucralose as a sweetener, which has been shown to have harmful effects and is suspected of causing cancer. It especially seems redundant in gainers which are full of maltodextrin, which has a higher glycemic index than sucrose anyway, so why not just use regular sugar as the sweetener for gainers? We are not protecting diabetics by removing sugar from a supplement that is already chucked full of maltodextrin.

2:35 I just want to add, for those who don't know, that the normal range for testosterone is very wide (240-950 ng/dl in adult males), and the level varies at different times of day. This might help understand why raising the level just a little bit with a supplement doesn't do much. You're just going from normal to normal.

[@alizaka1467]

True. Also to build muscle, you need raised levels of Test for long periods of times. Most Test boosters that do work i.e raise Test by insignificant margins, raise Test for a very short time, like a small spike in a graph and then the effect instantly wears off. That is completely useless for muscle growth.

[@quAdxify]

This is right and wrong. Right because the numbers check out. Wrong because it is not stratified by anything (age, obesity, and other high-impact factors like cortisol). So yes technically if you are a 20 yo, fit guy with 250 ng/dl, it is "normal". However, in actuality, it is likely abnormal and should be checked if any symptoms of low T are present. If you get the same readings as a 60-year-old obese pre-diabetic, you are perfectly fine (not in a general sense but there is likely nothing wrong with your T).

[@EbonyPope]

Going from the lower end to the higher end still means normal levels but the amount of muscle you are able to build and keep with 950 ng/dl is way higher. The problem is that the increase isn't as dramatic as people expect. But it's not true that you wouldn't notice it if it let you keep the upper end of the spectrum.

Jeff, as you mentioned, with BCAAs, there may be exceptions where they might be beneficial. When I suffered through hepatitis B, which was chronic/ active for four years, I gained some benefits from adding BCAAs to my supplement program, since my liver was so severely compromised. At my worst point, I was down to 127 lbs. and at 5' 10", looked awful! I had a discussion with my doctor before starting a bodybuilding program while the infection was still active and he suggested that BCAAs might be helpful in maintaining a positive nitrogen balance while having less stress on the liver. Of course that wasn't the only supplementation involved, (I was consuming close to 7000 calories/day), but I was able to gain 30 lbs of muscle over the next year and plateaued at 157 lbs and 11% body fat. I can't say for sure what part the BCAAs played in this situation, but there was certainly no harm and I eventually seroconverted another year later. Decades have passed since then and my liver panels were so normal, that we stopped testing in 2005. I understand liver cells can regenerate and that appears to be the case for me. What are your thoughts on this particular scenario?

[@ethanmerchant1812]

If ashwhaganda (definitely just messed up the spelling) does in fact lower cortisol level, meaning you’re less stressed, then it should actually increase testosterone, as testosterone decreases as cortisol and stress levels increase. Doesn’t mean that it does, but something to look into 1:30 Edit: I noticed when I watched I back that examine also showed increased sleep quality when taking the supplement, and good sleep in the 8-9.9 hour range has been shown to have an increase in testosterone

[@tzahi12370]

Yes boron can increase your free testosterone but not the total T ,and it has some lowering estrogen effect too.

[@elduderino1329]

Here is the study: Boron possesses widespread properties in biochemistry and nutrition. Acute supplementation with 11.6 mg of boron resulted in a significant increase in plasma boron concentration. Given such a fast bioavailability, the objective was to determine whether acute (hourly or daily), and weekly supplementation could have any significant biological effects on the steroid hormones and further on some inflammatory biomarkers. Eight healthy male volunteers attended the laboratory on three occasions (days 0, 1 and 7). On the first day (day 0), a blood sample collection at 8.00 A.M was followed by ingestion of placebo with the breakfast. On the next day (supplementation-day 1), similar procedure was followed by ingestion of a capsule containing 10mg of boron. On both occasions blood was collected every 2h for the next 6h. Subjects were requested to consume a capsule of 10mg boron every day with their breakfast, and on the day 7, the blood collection was carried out at 8.00 A.M, again. Boron in plasma increased significantly following hours and weekly consumption. Six hours supplementation showed a significant decrease on sex hormone binding globulin (SHBG), high sensitive CRP (hsCRP) and TNF-α level. After one week (in samples taken at 8.00 A.M, only), the mean plasma free testosterone increased and the mean plasma estradiol decreased significantly. Dihydrotestosterone, cortisol and vitamin D was elevated. Also, concentrations of all three inflammatory biomarkers decreased after supplementation. Of note, despite decreased proinflammatory cytokines, based on recent clinical data, this must be the first human study report to show an increase level of free testosterone after boron consumption.

I walked down the street and almost got hit by a car after my dog Snicker got lose. I was severely dehydrated and hadn't eaten much in those 3 days. Walking down the street thirsty I wanted to get me a drink at the town's carryout. I didn't make it there. a big Mac truck carrying coal came straight my way and I walked straight in front of it. I went through the truck. Jesus saved my life for the second time in my earthly existence. As I continued walking down the road a neighbor in a small truck was pulling in his driveway. I went up to his parked truck and wanted to steal it to assassinate a person. Jesus Christ (the one true living God) immediately started preaching to the man through me. The man that tried to kill me was simply coming home from somewhere and was at the wrong place at the wrong time. and he did not listen to me as he thought I was out of my mind. The man hit me in the head 3 times with a short club. My skull was fractured but God saved my life that night. I went to the hospital, and the next morning I was admitted to the Pysch ward.

[@calisthenics_progress]

I agree with most of the points with the exception of beta-alanine. Full disclaimer that the only time I personally consume it is when I take my C4 preworkout (1.6 g of CarnoSyn), so the turbo boost that I experience unfortunately cannot be attributed to beta-alanine alone. However, I still want to argue that the research you cited: "β-alanine supplementation to improve exercise capacity and performance: A systematic review and meta-analysis" does not properly represent the weight training audience. Their exercise protocol consists of mostly endurance workout such as 1~20 km cycling, 2 km rowing, 2.5~4 km running, etc. Even the non-endurance workout they experiment on does not really reflect "power" or "strength" that we are looking for at the gym. Those non-endurance exercises listed are: 100~400 m sprint, squat jumps, 30 seconds cycle sprints, etc. We all know for a fact that beta-alanine is effective for endurance sports. But the question is, how effective is it for strength and power? And is the overall effect anabolic? I don't think this particular research does a good job in answering these questions. Additionally, the research does not take into effect that gym sessions doesn't end after one short bouts of 30 seconds cycle sprints. Most of us spend a good hour doing various exercises for sets. It's no mystery that you will feel more fatigued nearing the end of the gym session. Some of this is from the depletion of glycogen in the muscle but also from lactic acid buildup, and our muscles can't contract effectively at low pH. Taking beta-alanine can neutralize the pH and delay the muscle fatigue, meaning we can train the same amount with more quality or perhaps with even more volume. Repeated increase in volume of training should effectively lead to synthesis of muscle over time. Putting aside the far extreme strength trainers taking 5+ min rest per sets taking multiple hours to complete their workouts, I would think that majority of the weight lifters who train at fairly high intensity can see the benefit of taking beta-alanine. You should also review this more recent study focused on strength training, although with less participants: Maté-Muñoz, J.L., Lougedo, J.H., Garnacho-Castaño, M.V. et al. Effects of β-alanine supplementation during a 5-week strength training program: a randomized, controlled study. J Int Soc Sports Nutr 15, 19 (2018). doi.org/10.1186/s12970-018-0224-0

[@ericks6609]

Thanks for linking this study, I hadn't seen this one and it certainly indicates that there is a discussion to be had on beta-alanine as a legitimate contributor to improved performance! The one common theme among beta-alanine studies I've noticed that gives me pause is the method of intake, which I haven't seen much information on; each study has the subjects consume small, regular doses of it with a regimen that seems unreasonable for the average lifter, and certainly not in line with what I would consider the current "normal" method of consumption, that being all in one go as part of a pre-workout formula. "Subjects in [The beta-alanine supplementation group] took 6.4 g/day of BA as 8 × 800 mg doses each at least 1.5 h apart". In a previous study I saw that they were consuming beta-alanine like 6 times a day also. I wonder to what extent the delivery method of the supplement effects the results, because as much as I would love to take beta-alanine for performance benefits, I simply cannot be bothered to take it every 2 hours all day everyday.

I also take beta-alanine. Though a note about it, it has also been shown in research that taking 6g at once is less effective than taking it in multiple doses throughout the day. So I do 2g doses, 3x a day which has been shown to have greater effect than one dose of 6g. I also do not take preworkout at all, however I am of the camp that you should take all non-immediate acting substances out of your preworkout. Generally, they are meant to be dosed at different timings than a preworkout, and since they don't have immediate effect then the only reason left to put them in preworkout is convenience, but even then that's only convenient if they are dosed appropriately. Things I would use in a preworkout: caffeine, arginine, citrulline Things I would prefer not in a preworkout: creatine, beta-alanine, protein

We’ve been spraying amino acids on chicken feed for the better part of a century. Chicken used to be an expensive “delicacy” that was reserved for Sunday dinner. Today, it’s relatively cheap and spray-on amino acids are a big part of why the cost of converting chicken feed to chicken has gone down. The problem in the 1940s was that chickens ate a lot of chicken feed to produce a little meat. The amino acid composition of chicken feed is, not surprisingly, quite different from chicken. Chickens ate what they were fed and used the available proteins to produce the “muscle growing” amino acids. That’s great. But the excess amino acids-the mix-matched amino acids were converted into carbohydrates by the chickens’ digestion lopping off the amine group and excreting it. Chicken poop smells as it does because the amine group smells like ammonia. By adding the critical amino acids (which are wildly expensive) the chickens got much more effective nutrition from improved feed. The financial benefit to pay for the amino acids came from chickens that matured faster and were less susceptible to “malnutrition.” The same is true for people. You can ignore the discussion of essential and branch chained amino acids and simply ask the question, “what amino acids are required-AND IN WHAT QUANTITIES-to build muscle.” Then you find that egg whites are five times better at supplying the critical amino acids than whey, for example. That quart of egg whites or the tub of whey isolate from Walmart costs about $0.04 per gram of generic protein-about the same, the egg whites have a five times better mix of amino acids. Grams of protein is irrelevant (for the most part) when 90% of the amino acids will be converted to fuel because they aren’t accompanied by the critical, muscle-building amino acids. The scientists who worked this out for chickens would tell you that building a body (for a chicken or a person) is like assembling the materials for a house. You need very specific items (eg, front doors, bathtubs, studs, joists, shingles, etc). If you get the wrong deliveries, your house will be expensive and built slowly. Get the perfect mix and the house will be cheap and fast. Almost 100 years after solving the problem for chickens, we don’t even address the problem for people. We expect muscle cells to cobble together the proteins in muscles from many near-miss amino acids-ones that are “close enough” to what the body needs. Jeff, with your education, you know this stuff!

The efficacy of supplements in general is greatly overstated, but the ones in this list are little more than a waste of money IMO. On the other hand, while supps like protein & creatine can certainly offer some benefits, they also require that many others factors are being done properly (ie. working hard enough, getting enough rest/recovery time, training frequency, proper nutrition, etc…), and even then the benefits aren’t going to be anywhere near as much as the supplement industry wants people to believe.

BCAAs are not taken to build muscle tissue but protect it during catabolism (excercise). The mechanism is that these 3 AAs, because they are branched, are the only ones that are not metabolized in the liver (there’s no enzyme to break them down in the liver). So they make it through small intestine directly into the bloodstream and then to muscle cells where they can be anaerobically broken down in mitochondria to produce energy. Technically they serve as a fuel during excercise (they are preferred by MAAO),thus limiting muscle tissue breakdown. You are only correct if we are talking post-workout supplementation for muscle recovery. Same goes for HMB (metabolite of leucine). The important thing is that BCAAs can cross BBB and compete with neurotransmitters like dopamine, so it is important to combine them with phenylalanine or tyrosine to keep the motivation and drive.

Some (my wife) would argue that if your gains are due to placebo effect from whatever supplement you're taking then it's still worth it.. But, a placebo that works for me may not work for you. Also, saying it works overall and putting a label on it that states what's in it is false advertising if what you stated isn't true. The whole supplement industry needs regulation. You'd see a lot of these companies disappear overnight because they know they couldn't meet the required standards. I'm currently on 500mg ecdysterone/day from NooTropics Depot. I figured if they were going to tear down other people's products then theirs must (should) be legit. It's been about a month give or take and I really can't tell if it's doing anything at all.

Lactate threshold is what should be used through out all of science. While many continue to use it, it is not correct. If lactic acid was actually a thing, increasing concentrations of it in the blood stream would completely throw off the pH balance of our blood.

I can vouch for a few of these raw supplements. I had my bloods taken and my test level was 11nmol/L and oestraidol was 120pmol/L so I started supplementing 5000iu of vitamin d3, 250mg DIM, 9mg Boron, 25mg Zinc, 100mg Magnesium and 450mg ashwaganda. After 3 months my test levels come back at 26nmol/L with 89pmol/L oestraidol. I was suspicious so I had them tested again the following month and my testosterone come back at 24nmol/L and oestraidol didn’t change. My diet remained the same and weight training stayed at 4 days per week. I’m unsure if I was deficient in any of these minerals/supplements beforehand, but they’re now a staple in my daily routine.

What does Boron and DIM do? Do u take those always daily or on the days after working out cause ik zinc and magnesium u lose through sweat. Wtf so double your test levels??? Over double. Did u take the blood test at the same time? for 11nmol/L and 26 nmol/L cause time it is taken is paramount.

No, you cannot vouch for these supplements.. three quarters of the western world are Vitamin D deficient.. and you took 5000iu of Vitamin D3, so it's highly possible.. that single supplement is responsible for those markedly improved markers.

I'd reinforce the notion that most "natural ways to boost" testosterone - unless someone has clinically relevant low levels - will (as noted at around 3:20) will not yield meaningful benefits. There have been studies that testoterone differences within the physiological range don't matter a lot when it comes to gaining and maintaining muscle mass. On a semi-related note, I think the obsession with "increasing" Testosterone due to supposed benefits (outside of muscle growth) is also a bit iffy. Hormones don't work in a linear fashion and in isolation. And in the same way that things cannot be broken down to "more tesosterone = more aggression" they can't be broken down into things like "more tesoterone = more muscles, more "Happiness" / less anxiety etc.

I am very interested to see if this can be answered conclusively though, and what the effect size (if any) is. I'm 96kg about 15% body fat, so I'm pretty big but nowhere near contest-ready.

I hope no one takes this as me debating. I’m not AT ALL. This is just food for thought …Thing is, there are always studies FOR and Against certain supplements. You’re going to find ones that show increase in athletic performance or not. Depends on SO many variables such as who is funding the study, type of sport, age, gender, how many athletes were used in the study, and more research is ALWAYS needed for a better conclusion etc. I think at the end of the day, if you take it and you see and feel it works (even if it’s placebo since placebo effect % is quite large) it’s still worth it in my opinion. I’m always skeptical of WHO funds the studies and if it’s bias 😅 if it’s one thing I learned in university and doing research in the exercise science field , it’s to not ALWAYS trust studies. Funding amongst other variables plays a HUGE role in results and what’s put out there :) awesome video! Great information and presentation 👏👏👏

its always a pleasure watching your videos, this is why I'm picky on my supplements and have been for over a dozen years, I've watched more and more come to the supplement industry but till practically take all the same with very little added into what i get,, I've always seen a bunch of it as if you're flushing your money down the toilet. thanks to scientific advancements.... it has made it easier than ever to help, thank you for what you do jeff!

[@bellasignora2668]

If I did feel the need to boost amino acids in bodybuilding such as yours, which should I choose, BCAA 4:1:1 or BCAA 2:1:1. Thank you...

[@chadlawrence2240]

I tried the Beta Alanine and can for me personally it worked incredibly well for making my overall workout easier. I was breezing through multiple sets much easier. Im not saying BA is for everyone but for me it clearly helps....also stack it with Baking Soda for greater effect.

3:30 the thing with testo boosters is that they mimic the feel of higher testosterone levels for a short time and therefor give the same perception. Its above placebo, some of the ingredients will give higher sex drive, higher motivation to dominate in fight, training and work, being less agreeable and so on. Its just not testosterone.

Amazing as always, Jeff. Curious about electrolytes. I use them in my water (biosteel) largely because 1. it tastes good, but 2. I figure it helps with hydration. I'm noticing that non of the evidence-based people I follow in the fitness world drink them though which makes me think I might be wasting my money haha.

[@yasa4091]

Not sure if I’m correct but logically water usually has a lot of minerals, which include “electrolytes”. Electrolyte supplements usually have carbs or sweeteners for the taste, which may be the reason u feel hydrated or more energetic (or just placebo, since u might drink more water since it tastes good).

[@daegrun]

@@yasa4091 Water has significant quantities of potassium and magnesium? Or just certain kinds of water? Idk…

[@cameronlaviolette1248]

@@yasa4091 some water like spring water has high mineral content but most city water has low mineral content and you should supplement minerals if you live in a city

I like Trace Minerals’ Mega-Mag 400g drops. It has 400mg of magnesium (95%DV), 1100mg of Chloride (48%DV), 5mg of sodium and 5mg of potassium (both less than 1% of DV)

[@noahgearhart4098]

As someone who works a physical job and is very active outside of that I swear a lot therefore I take extra electrolytes to help replace that. Different people have different sweat rates and electrolyte concentrations so it could be very different. I think if you sweat a lot it’s probably a good idea.

Right into Greg's heart... You could have gone for just the leg 😄

So Jeff, on BCAAS I have a bone to pick. I react badly to whey protein and had to switch to a vegan protein b powder. I supplement alongside my powder with bcaas and see no deleterious effects. So while consumed alone they're not effective but alongside a vegan powder they are. I don't have to eat extra or double the vegan powder when I consume a shake when I throw in one scoop of BCAAS. Cheers

I'm 17 Years old, 5'9 174 lbs. I've been doing push pull legs for almost a week now and I am a bit confused on sets and reps. I'm striving for ultimate hypertrophy and doing a body recomp simultaneously. So I'm in a calorie deficit of about 1,800 calories, and hit around 170 grams of protein everyday. I workout in my garage and have a full body workout machine and some dumbbells, treadmill, and a bar and weights. I have been doing my targeted muscles every day and doing one set that consists of about 15 - 20 reps always until failure. And then I finish off with holding 10 lb dumbbells on treadmill on max incline for around half a mile or more. Every time I do my exercises until failure which ore low reps high weight it feels like I have more in me or that I'm not doing enough but then I read online that that's all I need to do for hypotrophy and anymore is pointless.

You need some one there to help you get that last bit of gas in your tank. Having a spotter help you to go a little bit above and beyond is really going to help.
