One serving of HMB 3000 contains 3,000 mg of calcium beta-hydroxy-beta-methylbutyrate, an ingredient which professional body builders have used for decades to reach their fitness goals. Due to the powder form and the unflavoured formula, the product is easy to dose and to add to other nutritional supplements. Like all BioTechUSA products, HMB 3000 consists of safe and carefully selected ingredients.
