Peptide-by-peptide comparisons
Side-by-side mechanistic and evidence-base summaries to help frame how the most-studied longevity peptides compare in the published research literature.
Epitalon vs Humanin
Two foundational longevity peptides with very different origins — one a synthetic pineal tetrapeptide, one a mitochondrially-derived peptide. Compared on mechanism, evidence base and research role.
GHK-Cu vs Thymosin Alpha-1
Cellular-repair vs immune-restorative. Two endogenous peptides with deep clinical histories but very different positions in longevity biology.
MOTS-c vs SS-31 (Elamipretide)
The two best-characterised mitochondrial peptides: one a signalling mitokine, one a structural cardiolipin stabiliser. Mechanism, evidence and research positioning.
Best longevity peptide stacks discussed in research
The combinations most-frequently appearing in the longevity research literature — GHRH+GHRP, MOTS-c+SS-31, AEDG+GHK-Cu — with mechanistic rationales and evidence gaps.
