You need to make it work
If this doesn't work on you it's because you are doing something wrong, remember that this product needs to be combine with a good diet and a good exercise routine to get result, otherwise you wont have a great body just because, this is a supplement used in athletes like football players, runners etc. the recommended doses by specialists in nutrition is 3 pills a day, two before workout and one after, we need to remember that the HMB is hydro soluble, that means that if you take more than you supposes to take, it will go out in the urine, so more than 3 a day it is a waste of product.

"A new lease on life!"
I started taking one a day on non-workout days. And two on workout days about two hours before my workout. In just two weeks I've noticed my muscle texture has become fuller and define in nature. I know it is recommended to take three a day, I will most likely work up to it. Also I've noticed more energy and less muscle pain, not a tremendous amount, just a little, but, it was noticeable!

Help Build Muscles
I am taking this product to help me build muscle as I work out. I am over 60 and have found it harder to build and maintain muscle mass but this product is really giving me results.

I usually take this supplement only on days that I lift and I have seen huge improvements on my overall tone throughout my body. It definitely works and is a good buy for any dedicated lifter!

Kevlar for your muscles
I use less than the suggested dosage, because I take in a lot of leucine. I stack it with creatine and glutamine.

HMB is the best thing that I take. It reduces muscle soreness to near zero. As a result, my workouts are longer and more intense, and 2x/day now. I have tested the effectiveness by pushing certain body parts well beyond their previous limits, and the next day, they felt fine.

I suggest this product to everyone that I discuss fitness with.

Great recovery supplement!!
This greatly improved my workouts and real world life afterwards. I normally am a little sore a day after a hard workout. Then a little more sore the next day and by the third day I hurt like hell. This kills my workouts. With HMB I can go all out and work the same muscle group two times a week and never really even get sore. If you are like me this is a must.

No miracle drug, but effective
This suppliment seems to be most effective for the first three or so months that you take it, and then it's effects seem to wane. Definitely one of my favorites to cycle through, though, using it for a couple of months and then dropping it for a month or so. It is expensive, though, because the recomended doses are 12 pills per day. Thus the 240 count bottle is actually less than a month's supply. If you have the cash, though, give it a try. I'm certain you'll notice obvious effects, especially if you've never taken it before.
