Mechanism of Action Comparison
How Epitalon Works
Epitalon Epitalon is a synthetic tetrapeptide studied for anti-aging effects, investigated for activating telomerase to lengthen telomeres and potentially extend cellular lifespan.
Lengthens telomeres via telomerase activation. May also regulate melatonin production and circadian rhythm, and modulate antioxidant enzyme activity.
How GHK-Cu Works
GHK-Cu GHK-Cu is a naturally occurring copper peptide studied for stimulating collagen production, accelerating wound healing, and reversing visible signs of skin aging.
Copper delivery for collagen/elastin synthesis. Activates tissue remodeling, attracts immune cells to injury sites. Levels decline significantly with age.
Key Mechanistic Difference
Epitalon operates as a telomerase activator, while GHK-Cu functions as a copper peptide — these are fundamentally different pharmacological approaches. Epitalon has a significantly longer half-life (~2 hours) compared to GHK-Cu (~30 minutes), which impacts dosing frequency and sustained activity.
