Overview

BulkSupplements HMB provides 3g of pure beta-hydroxy beta-methylbutyrate (HMB) per serving with no fillers or additives. HMB is a metabolite of the amino acid leucine that has been shown to reduce muscle protein breakdown (proteolysis) during caloric restriction, intense training, and recovery from injury. The 3g dose is the clinically studied amount shown to preserve lean mass during cutting phases and accelerate recovery. HMB works through a different mechanism than leucine itself — while leucine stimulates MPS, HMB inhibits the ubiquitin-proteasome pathway that breaks down muscle protein.
