What is HGH 191AA (Somatropin)?
191AA is a recombinant human growth hormone containing the exact 191-amino acid sequence found in endogenous pituitary growth hormone. It is produced using recombinant DNA technology in Escherichia coli. The peptide acts as a primary endocrine regulator of growth, cellular reproduction, and metabolic homeostasis. Exogenous administration aims to restore physiological growth hormone levels in cases of deficiency or age-related decline. The lyophilized formulation ensures stability until reconstitution for subcutaneous delivery.
