Anabol Naturals products are the highest quality pharmaceutical grade free-form amino acids -- crystalline form for assimilation directly into the body without need of digestion. Made to U.S. Pharmacopeia (USP) quality, purity and potency standards. Food protein is formed by long chains of molecularly bonded amino acids. The body must first break these molecular (peptide) bonds for amino acid absorption. Anabol Naturals' amino acids are already in their simplest single, free-form molecular state (no peptide bonds), and can readily be absorbed.
