AOD-9604's structure replicates the C-terminal fragment of human growth hormone (amino acids 176–191), the region identified as responsible for HGH's fat-reducing effects without its insulin-antagonistic properties. Preclinical s…
Let's be direct: calling AOD-9604 an alternative to Wegovy conflates two entirely different categories of compounds. One is a research peptide with inconclusive human data and no regulatory approval. The other is a prescription m…
