Anti-Aging Peptides
Anti-aging peptides are studied for their potential to slow the biological aging process through various mechanisms including telomere protection, epigenetic modulation, mitochondrial support, and reduction of cellular senescence.
Overview
The science of peptide-based anti-aging intervention is rooted in the understanding that aging is not simply a passive process of wear and tear, but an active biological program that can potentially be modulated. Anti-aging peptides target multiple hallmarks of aging simultaneously.
Epitalon (Epithalon) is perhaps the most extensively studied anti-aging peptide. Developed by Russian scientist Vladimir Khavinson over decades of research, it is a synthetic tetrapeptide that has demonstrated the ability to activate telomerase, potentially extending cellular lifespan.
GHK-Cu (Copper Peptide) represents another important category — naturally occurring in the body but declining with age. Research shows it can reset gene expression of aging cells to patterns more similar to young cells, affecting over 4,000 genes.
Key Compounds
Epitalon
TetrapeptideSynthetic tetrapeptide (Ala-Glu-Asp-Gly) that activates telomerase. Extensively studied in both animal and human longevity research.
GHK-Cu
Copper peptideTripeptide that declines with age, resets aged gene expression profiles, promotes collagen synthesis and tissue repair.
Humanin
MitochondrialMitochondrially-encoded peptide with cytoprotective effects. Declines with age and is associated with longevity in centenarian studies.
MOTS-c
MitochondrialMitochondrial-derived peptide that regulates metabolic homeostasis and stress responses. Exercise mimetic properties in research.
SS-31 (Elamipretide)
MitochondrialMitochondria-targeted tetrapeptide that protects cardiolipin and improves mitochondrial function. In clinical trials for heart failure.
Thymalin
ThymicThymic peptide complex studied extensively by Khavinson for immune restoration and longevity in elderly populations.
Mechanism of Action
Telomerase Activation
Peptides like Epitalon activate telomerase reverse transcriptase (TERT), potentially slowing telomere shortening with each cell division.
Epigenetic Reprogramming
Some peptides influence DNA methylation patterns and histone modifications, reverting aged epigenetic states toward younger profiles.
Mitochondrial Protection
Mitochondrial-derived peptides protect the energy-producing organelles from age-related dysfunction and oxidative damage.
Senolytic Effects
Certain anti-aging peptides may selectively eliminate senescent cells that contribute to tissue dysfunction and inflammation.
