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.

Dimensionmots-caod-9604Notes
MechanismMitochondrial metabolic regulationLipolysis (HGH fragment 176-191)MOTS-c activates AMPK and improves cellular metabolism. AOD-9604 mimics the fat-burning portion of growth hormone.
Weight Loss EvidencePreliminary (strong animal data)ModerateAOD-9604 has more direct fat loss studies. MOTS-c research focuses on metabolic function broadly.
Additional BenefitsExercise mimetic, insulin sensitivityTargeted fat reductionMOTS-c acts as an exercise mimetic. AOD-9604 is more narrowly focused on fat metabolism.
Side EffectsMinimal reportedMinimal reportedBoth well-tolerated in available data.
FDA StatusResearch onlyResearch onlyNeither is FDA-approved for any indication.
Cost$60-120/vial$30-50/vialMOTS-c tends to be more expensive due to synthesis complexity.
