This comparison does not assign a generated winner or score.
- MOTS-c
- AMPK activation, nuclear gene regulation via mitochondrial retrograde signaling
- Glucose uptake, insulin sensitivity, mitochondrial biogenesis
- Metabolic adaptations (not strength or endurance capacity)
- Preclinical (animal models, early human trials)
- Strongest evidence for metabolic regulation; does not replace physical conditioning
- Humanin
- Binds FPRL1 receptor, inhibits apoptosis, improves insulin signaling
- Neuroprotection, glucose metabolism, cytoprotection
- Metabolic resilience pathways
- Preclinical
- More focused on cytoprotection than exercise replication
- GW501516 (Cardarine)
- PPARδ agonist, increases fatty acid oxidation
- Endurance capacity, fat oxidation
- Endurance adaptations (oxidative metabolism)
- Preclinical (discontinued in clinical trials due to cancer concerns)
- Effective for fat oxidation but significant safety concerns
- AICAR
- Direct AMPK activator
- Glucose uptake, mitochondrial biogenesis
- Metabolic adaptations
- Less specific than MOTS-c; broader AMPK effects
- SLU PP 332 Peptide
- ERRα/γ agonist, enhances oxidative metabolism
- Mitochondrial biogenesis, fatty acid oxidation
- Oxidative metabolism pathways
- Early preclinical
- Promising mechanism targeting mitochondrial quality
- The critical distinction: MOTS-c is mitochondrial-encoded and functions through retrograde signaling, meaning it's part of the cell's endogenous metabolic regulation system rather than an exogenous pharmaceutical override. Compounds like GW501516 work by activating nuclear receptors (PPARδ) but aren't naturally produced by the body. MOTS-c levels decline with age and metabolic dysfunction, so supplementation aims to restore a physiological signal the body already uses but produces less of over time.
