- Before selecting a peptide for endurance research, compare mechanism, dosing logistics, and the specific metabolic outcome each compound targets.
- | Compound | Primary Mechanism | Dosing Frequency | Key Metabolic Outcome | Half-Life | Professional Assessment ||—|—|—|—|—|| SLU-PP-332 | ERRα/PPARδ agonist. Direct mitochondrial biogenesis | Once daily (subcutaneous) | 450% increase in oxidative capacity markers | ~18 hours | Best choice for studies targeting mitochondrial density without exercise stimulus. The only compound with direct PGC-1α activation independent of AMPK || MK-677 | Ghrelin receptor agonist. Pulsatile GH secretion | Once daily (oral) | IGF-1 elevation (mean +50% from baseline) | ~24 hours | Ideal for recovery-focused protocols. Accelerates glycogen resynthesis and reduces time to baseline power output after depletion || Mazdutide | Dual GLP-1/glucagon agonist. Metabolic rate + substrate shift | Once weekly (subcutaneous) | 12% increase in RMR; 34% increase in fat oxidation | ~7 days | Best for studies examining metabolic flexibility and substrate preference. The RER shift mimics trained athlete metabolism || Carta
