I took this together with creatine because it is supposed to be synergistic. Though I didn't feel any difference, there could have been. Primaforce seems good though. I take other stuff from them.

Great for recovery and reducing muscle fatigue.
Verified purchase
HMB is a phenomenal supplement that has no known side effects. It is an acid that is derived from the breakdown of leucine and as such, is naturally produced in the body. However, research suggests that supplementing your body with HMB can increase muscle recovery speeds (thereby decreasing fatigue) while also increasing your lean mass (which CAN lead to a decrease in fat, as long as your diet is good and you exercise regularly enough for you to be in a deficit that would allow for it). While some of the HMB I've had didn't taste great and some the capsules I've had have been quite large, the size of these capsules and taste of them have not been nearly as bad. The quality of the ingredients seems about as good as any other brand. As always, I suggest you do your own research on this supplement (try using pubmed or ncbi).
