AOD-9604 and Semaglutide are both Metabolic peptides, but they're studied for different things. In short, AOD-9604 is a growth-hormone fragment studied for fat metabolism, while Semaglutide is a GLP-1 receptor agonist approved for type 2 diabetes and weight management. This page compares the two side by side — what each is researched for, how mature the evidence is, and how they're typically used — so you can see where they overlap and where they differ. It's educational information only, not medical advice, and neither is a substitute for a conversation with a licensed professional.

How does AOD-9604 work?
AOD-9604 is a modified fragment of the C-terminus of human growth hormone (residues 176-191). It was designed to stimulate fat metabolism (lipolysis) without the growth-promoting or blood-sugar effects of full-length growth hormone.
How does Semaglutide work?
Semaglutide is a GLP-1 receptor agonist that mimics an incretin hormone released after eating. It slows gastric emptying, increases satiety, and improves insulin response — mechanisms that underpin its FDA-approved use in type 2 diabetes and chronic weight management.
AOD-9604 vs Semaglutide: how to choose
Choosing between AOD-9604 and Semaglutide really comes down to your specific goal — and it's a decision for you and a licensed professional, not something to settle from a web page. AOD-9604 is most associated with Fat metabolism and Body composition, while Semaglutide leans toward Blood sugar regulation and Appetite & weight management. Where they overlap, the practical differences are usually in mechanism and how far the research has actually progressed.

Frequently asked questions
Both are Metabolic peptides. AOD-9604 is a growth-hormone fragment studied for fat metabolism; Semaglutide is a GLP-1 receptor agonist approved for type 2 diabetes and weight management. They're most researched for Fat metabolism, Body composition (AOD-9604) and Blood sugar regulation, Appetite & weight management (Semaglutide), respectively.
There's no universal "better" — it depends on your goal, and for most of these compounds robust head-to-head human evidence doesn't exist. The right choice is one made with a licensed professional. Selpho does not rank or prescribe; it offers educational information and a research-backed advisor.
They're in the same category, and combining research compounds is something to approach only with a licensed professional, since interactions and individual context matter. Selpho provides no dosing or protocols.
AOD-9604: Human trials for obesity did not meet primary endpoints; further research ongoing. Semaglutide: FDA-approved with large-scale human clinical trials.
