- Before selecting peptides for research protocols, understanding their distinct mechanisms and evidence levels prevents redundant pathway targeting and identifies synergistic combinations.
- Epithalon
- Telomerase activation, pineal function restoration
- Replicative senescence, stem cell exhaustion
- Animal models + small human cohorts
- Most direct telomere maintenance peptide; Russian literature extensive, Western replication limited
- Ipamorelin
- Selective ghrelin receptor agonist (growth hormone secretion)
- Loss of proteostasis, altered intercellular communication
- Preclinical + Phase II human trials
- Cleanest GH secretagogue profile; minimal cortisol/prolactin elevation vs other GHRPs
- MOTS-C
- Mitochondrial-derived peptide, AMPK activation, metabolic regulation
- Mitochondrial dysfunction, deregulated nutrient sensing
- Animal models + early human metabolic studies
- Unique mitochondrial-to-nuclear signaling; improves glucose tolerance and exercise capacity
- SS-31 (Elamipretide)
- Cardiolipin stabilization in inner mitochondrial membrane
- Mitochondrial dysfunction
- Phase II trials for heart failure and mitochondrial disease
- Most targeted mitochondrial protectant; concentrates 1000× in mitochondria vs cytoplasm
- FOXO4-DRI
- Senolytic (induces apoptosis in senescent cells)
- Cellular senescence
- Animal models, mechanism validated in human cells
- Only peptide senolytic with published in vivo rejuvenation data; selectivity for senescent cells verified
- Thymosin Alpha-1
- Thymic immune restoration, T-cell differentiation
- Immunosenescence
- FDA-approved (non-US), extensive human safety data
- Strongest clinical evidence base; approved therapeutic in 35+ countries for immune restoration
