Optimum NutritionHMB 1000 Caps, 1g of Calcium beta-Hydroxy beta-methylbutyrate per Capsule, 90 Capsules, 30 Servings

I haven't read any reviews on this stuff in a long time. From my previous knowledge and current experience, HMB is good for the first month or two of strength and mass gaining then it tapers off. Some people may have different stories, but if they have been at it a while, I doubt this helped them much, unless they really up their game and/or it had a placebo affect. I think most research and most users, only get that real benefit during that first few months, and really only for about two months of using this. That doesn't mean it doesn't help beyond that, but I am pretty sure for the cost, you have other options that will do you better. I have used it before and definitely got results. I had a layoff for a few years, I did not use it my first decade of working out. So when I got back into it and used this. Yeah, it helped for those few months. After some injuries, I am going at it again, and this is gonna be part of my regimes for two months, once I get through a few weeks of working my body back into the groove.

This is a good supplement to take post work out with a meal to elevate muscle growth and stability along with a regular diet. I have been trying to cut back on overall calories and this seems to be helping with sustaining muscle and faster rehab between workouts.

These are pretty expensive and you have to take 3 a day but overall they’re great

Good Supplement, but gets pricey fastHMB is a great supplement, only thing that has stopped me taking it in the past is that you usually need pretty high dosages for it to work. I wanted to try it finally and optimum has the best price and their other products have always been of good quality. I am taking 5 grams daily, which is 5 pills per day. This is the way to get results, do your research and you'll realize you're looking at less than a 30 day supply. Not a problem because I the gains I made it worth every penny. I will always try to stack it with Beta Alanine; ★ 50% Off Sale Today Only ★ Pure Beta Alanine Powder (200 Grams - Over 100 Servings) ★ Delay Muscle Fatigue - Promote Muscular Endurance - Improve Workout Performance ★ Try it 100% Risk Free. It can get expensive when you start stacking things with HMB during the same cycle but the beta is insane for increasing energy and combating muscle fatigue during the workout. I will probably do another cycle in a couple months and continue to do so.Nothing bad to say about any of these supplements, looking to increase weight by 20 pounds over the next six months and want to maximize the amount of muscle that is, and minimize the fat...these kinds of supplements are the best thing for that, hands down.

I have no medical background so this is purely a layman's review. I am old (61) and decided to try this because of the "Ensure Muscle" product advertising (EM is too expensive and too high in calories). I'm semi-retired so I do put in a lot of gym time. After about 10 months of weight training and cardio and taking HMB for the last four months, I can say that I'm in the best shape of my life. I'm more ripped than I ever thought I could be at my age. So I believe it works. Can't be sure, but I think it does work. I'm going to stay on it.Edit 10/07/13: There's no doubt this stuff works. I've been on this since March 2011 and I will continue taking it. I'm now 64 and my physique looks downright unnatural for someone my age. I live in a condo with an outdoor pool and I'm afraid my neighbors think I'm doing steroids. Now, it isn't without work; as I mentioned above, I am mostly retired, have a lot of free time and spend a lot of time in the gym doing weights, running and now spin class (love it). This is good stuff and not expensive, considering the benefits it gives.

Necesario a partir de cierta edad

I think this is an OK product. From what I have seen and heard, Optimum Nutrition seems to be a solid company (I realize this is opinion open to rebuttal). So I think this product does have the dose of HMB advertised. But like most supplements of the bodybuilding kind, it is usually difficult to tell if something is really working at an above average level. To put this in context, when I have tried certain brands of creatine (promera con crete comes to mind), or pre-workout mixes (for example Cellucor C4), I noticed immediate short term benefits. Or when I stopped taking a multi-vitamin (was taking Universal Animal Pak at the time), and a week later noticed that I had a more difficult time getting out of bed and energy levels had declined. With HMB though, I haven't seen dramatic differences in performance. Does that mean it doesn't work? I can't say no, but I also can't say that this is worth the cash if you are on the fence about getting this.Bottom line is that in the end, if vast majority of reviews are good, it is usually worth a try. Everyone is different and what did not provide dramatic results for me, may provide gains for you.Just be sure you have the basics down first (protein, multi vitamin, solid routine etc) and then when you are looking for something new, you can consider giving HMB a shot.
