Apex Formulas HMB

HMB (beta-hydroxy beta-methylbutyrate) is a metabolite of the amino acid leucine, and its job is a defensive one: reducing the rate at which muscle protein is broken down.

That makes it most useful in the situations where muscle is genuinely at risk — training in a calorie deficit, very high training volumes, returning from a layoff, or long endurance blocks. It is not a stimulant and it will not give you a training buzz; it works quietly in the background to help you hold onto the muscle you already have.

Unflavoured powder, so it mixes into a shake or intra-workout drink without interference. Take it consistently rather than only on training days — HMB works on accumulation, not on acute dosing.

240g tub, unflavoured.
