AOD-9604 and MOTS-c 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 MOTS-c is a mitochondrial-derived peptide studied for metabolism and exercise. 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 MOTS-c work?
MOTS-c is a peptide encoded within mitochondrial DNA that acts as a metabolic regulator, influencing insulin sensitivity and energy homeostasis — partly through AMPK, a key cellular energy sensor. It is studied for metabolic health and exercise capacity.
AOD-9604 vs MOTS-c: how to choose
Choosing between AOD-9604 and MOTS-c 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 MOTS-c leans toward Insulin sensitivity and Metabolic health. 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; MOTS-c is a mitochondrial-derived peptide studied for metabolism and exercise. They're most researched for Fat metabolism, Body composition (AOD-9604) and Insulin sensitivity, Metabolic health (MOTS-c), 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.
