MOTS-c vs AOD-9604: Metabolic Peptides for Fat Loss Compared
Compare MOTS-c (mitochondrial peptide) vs AOD-9604 (HGH fragment) for fat loss. Different mechanisms, research evidence, and which fits your goals.
| Dimension | mots-c | aod-9604 | Notes |
|---|---|---|---|
| Mechanism | Mitochondrial metabolic regulation | Lipolysis (HGH fragment 176-191) | MOTS-c activates AMPK and improves cellular metabolism. AOD-9604 mimics the fat-burning portion of growth hormone. |
| Weight Loss Evidence | Preliminary (strong animal data) | Moderate | AOD-9604 has more direct fat loss studies. MOTS-c research focuses on metabolic function broadly. |
| Additional Benefits | Exercise mimetic, insulin sensitivity | Targeted fat reduction | MOTS-c acts as an exercise mimetic. AOD-9604 is more narrowly focused on fat metabolism. |
| Side Effects | Minimal reported | Minimal reported | Both well-tolerated in available data. |
| FDA Status | Research only | Research only | Neither is FDA-approved for any indication. |
| Cost | $60-120/vial | $30-50/vial | MOTS-c tends to be more expensive due to synthesis complexity. |
Learn more about each peptide
MOTS-c
MOTS-c is a mitochondrial-derived peptide that regulates metabolic homeostasis and has been called an "exercise mimetic" for its ability to activate AMPK pathways.
AOD-9604
AOD-9604 is a modified fragment of human growth hormone (hGH fragment 176-191) that stimulates fat breakdown without the growth-promoting effects of full HGH.
