10 Vials of 10IU, 12IU, 16IU, or 24IU HGH (191AA) – Lab-tested, high-purity recombinant human growth hormone peptide. Supports body composition, metabolic, and cellular regeneration research with secure payment and fast, discreet shipping.
HGH (191AA), also known as human growth hormone (somatropin), is a 191-amino acid single-chain polypeptide naturally produced by the pituitary gland. It plays a central role in growth, cell regeneration, metabolism, and body composition by stimulating the liver to produce IGF-1, which promotes tissue growth and development.
It features two disulfide bonds (Cys53–Cys165 and Cys182–Cys189) and forms a four-helix bundle structure essential for binding to the growth hormone receptor (GHR). HGH is secreted in pulses, primarily during deep sleep, and regulates muscle growth, fat metabolism, bone density, and organ function.
In research, HGH (191AA) is used for anti-aging, muscle recovery, fat loss, and metabolic studies. It is distinct from shorter fragments like HGH Frag 176-191, as it provides full systemic GH activity.
