A dual GIP and GLP-1 receptor agonist developed by Eli Lilly. Represents the next generation of incretin-based therapies with potentially superior efficacy to semaglutide for weight loss.
A modified fragment of human growth hormone (amino acids 177-191) originally developed as an anti-obesity agent. Targets fat metabolism without the growth-promoting effects of full HGH.
Activates both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors, producing enhanced insulin secretion, appetite suppression, and metabolic improvements beyond what single-agonist drugs achieve.
Stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat formation) by mimicking the fat-reducing action of natural growth hormone without affecting blood sugar or tissue growth.
