AOD-9604
WellnessAlso known as: Advanced Obesity Drug 9604, Anti-Obesity Drug 9604, Tyr-hGH Fragment 177-191
Limited EvidenceWhat is AOD-9604?
A modified fragment of human growth hormone (amino acids 177-191) developed for fat loss. Despite promising early research, it failed to demonstrate efficacy in large clinical trials and was not approved by the FDA.
How it works
Mimics the lipolytic (fat-burning) region of growth hormone without affecting blood sugar or growth. Stimulates the breakdown of stored fat (lipolysis) and inhibits the formation of new fat (lipogenesis) by acting on beta-3 adrenergic receptors in adipose tissue.
