Anti-aging peptides represent a rapidly growing category with some of the most intriguing research in longevity science. Epithalon has the only human data showing actual telomere lengthening. GHK-Cu declines with age and its restoration shows remarkable systemic effects. Khavinson bioregulators are backed by 40+ years of Soviet and Russian clinical research.
Epithalon: Telomere Extension
Epithalon (Epitalon) is a synthetic tetrapeptide that activates telomerase — the enzyme that rebuilds shortened telomeres, which are one of the primary biological clocks of aging.
Key studies: Human clinical trials (Khavinson et al.) demonstrated measurable telomere lengthening after Epithalon administration in elderly patients. Average telomere length increased 33% in one study.
Dosing: 10mg/day for 10-20 day courses, 1-2x per year. Available injectable (SubQ or IM) or sublingual.
Unique: the only peptide with replicated human data for telomere extension.
GHK-Cu: The Anti-Aging Tripeptide
GHK-Cu (glycine-histidine-lysine copper complex) is a naturally occurring tripeptide that declines from ~200ng/mL at age 20 to ~80ng/mL at age 60. Loren Pickart's decades of research show GHK-Cu upregulates >300 genes associated with repair and downregulates inflammatory pathways.
Clinical evidence: Widely used in wound healing, skin rejuvenation, and hair growth. Topical application is FDA-cleared for wound care.
Dosing (injectable): 1-2mg/day SubQ, 4-6 week courses
Topical: 1-2% creams applied to skin or scalp
Unique: works both systemically and topically with different but complementary effects.
Khavinson Bioregulators
Vladimir Khavinson developed a class of organ-specific peptide bioregulators over 40+ years of Soviet/Russian research. Each targets a specific organ's gene expression:
Pinealon (brain/pineal): Reduces neuronal apoptosis, improves cognition in aging
Cortagen (cerebral cortex): Normalizes cortical function, studied for vascular dementia
Cardiogen (heart): Cardioprotection, myocardial repair
Thymalin (thymus): Broad immune restoration, 2-2.4x reduction in acute infections in elderly trials
Endoluten (pineal): Natural pineal peptide complex, melatonin regulation
These are typically cycled 10-day courses 2x per year.
Supporting Anti-Aging Compounds
MOTS-C: Mitochondrial-derived peptide that acts as a metabolic regulator, improving insulin sensitivity and mimicking caloric restriction.
SS-31 (Elamipretide): Targets the inner mitochondrial membrane to reduce oxidative stress and restore ATP production. In Phase 2/3 trials for mitochondrial myopathy and heart failure.
NAD+ / NMN: Not peptides per se, but coenzymes that decline with age. IV NAD+ therapy and oral NMN supplementation are among the most studied longevity interventions.
Key Takeaways
The most evidence-backed anti-aging peptide protocol combines Epithalon (for telomere support), GHK-Cu (for gene expression restoration), and Thymalin (for immune function). These three have the strongest human clinical data in the anti-aging category.
