Is HMB really effective?
In brief, HMB supplementation is effective in increasing myofibrillar protein synthesis via the mTOR pathway and the growth hormone/IGF-1 axis, and in preventing muscle protein breakdown via the ubiquitin proteasome and the autophagy-lysosome systems.
Is HMB worth bodybuilding?
It appears that HMB does have many positive effects that can lead to increased gain in lean mass and decreased muscle breakdown and is therefore a valuable supplement.
Is HMB safe for long term use?

Which is better leucine or HMB?
When compared to leucine, HMB appears to be significantly more potent on a gram per gram basis at attenuating the rate of muscle protein breakdown but is less effective than leucine at inducing muscle protein synthesis.
What are HMB supplements and how do they work?
The body naturally produces HMB in small amounts when it metabolizes the amino acid leucine. People take supplements to raise HMB levels in the body. This may aid muscle growth and performance.
What is HMB and is it safe?
