Anti-Aging Peptides

Peptides targeting the hallmarks of aging — from telomere maintenance and senescent cell clearance to mitochondrial optimization and immune restoration. A look at the science of peptide-based longevity interventions.

Category Overview

Anti-aging peptides target various hallmarks of aging: telomere shortening, mitochondrial dysfunction, cellular senescence, immune decline (immunosenescence), and extracellular matrix degradation. While no peptide has been proven to extend human lifespan, several show compelling mechanisms for slowing age-related decline.

GHK-Cu is the most well-researched anti-aging peptide, with data showing it can modulate expression of over 4,000 human genes — many in directions associated with younger, healthier tissue. Newer entries like FOXO4-DRI (senolytics) and mitochondrial peptides (SS-31, MOTS-c) represent cutting-edge approaches.

Reality check: Most anti-aging peptide research is preclinical (animal models and cell studies). Extrapolating these results to human longevity requires caution. The most evidence-supported approach remains lifestyle optimization (exercise, nutrition, sleep) with peptides as potential adjuncts, not replacements.

All Anti-Aging Peptides

GHK-Cu

Copper tripeptide with extensive research showing gene expression modulation (over 4,000 genes), collagen synthesis stimulation, antioxidant activity, and tissue remodeling. Available topically and injectable.

Epitalon (Epithalon)

Tetrapeptide studied for telomerase activation and potential telomere lengthening. Based on the work of Dr. Vladimir Khavinson. Limited but intriguing human data from Russian clinical studies.

Thymosin Alpha-1

Immune-modulating peptide that supports thymic function — critical because thymus involution is a hallmark of aging. Approved in several countries for immune support. May help restore youthful immune function.

FOXO4-DRI

Peptide designed to induce apoptosis of senescent (zombie) cells — a senolytic approach. Showed promise in aged mice (restored fitness, fur density, renal function). Very early-stage research.

BPC-157

While primarily a healing peptide, BPC-157's broad tissue-protective and regenerative effects have anti-aging implications, particularly for gut health and systemic inflammation reduction.

SS-31 (Elamipretide)

Mitochondria-targeted peptide that reduces oxidative stress and improves mitochondrial function. In clinical trials for mitochondrial diseases and age-related heart failure.

MOTS-c

Mitochondrial-derived peptide that improves metabolic function and exercise capacity. Showed anti-aging effects in animal models. Naturally produced but declines with age.

Humanin

Mitochondrial-derived peptide with neuroprotective and cardioprotective effects. Levels decline with age. Being studied for Alzheimer's disease and age-related cognitive decline.
