HGH (191AA) is a recombinant polypeptide consisting of the full 191–amino acid sequence identical to endogenous human growth hormone (somatotropin).
It is widely studied for its influence on cellular growth, tissue repair, protein synthesis, and metabolic regulation through activation of growth hormone receptors and downstream IGF-1 pathways.

HGH (191AA) supports research in regenerative biology, muscle and connective tissue studies, and metabolic signaling models, making it one of the most extensively studied growth-related peptides in modern laboratory research.
