Epithalon vs GHK-Cu

Epithalon vs GHK-Cu — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Epithalon
Longevity & Telomere

Epithalon is a synthetic tetrapeptide derived from the pineal gland bioregulator Epithalamin. It activates telomerase to extend telomeres and slow cellular senescence, and regulates melatonin production and circadian rhythm. Administered in 10-20 day courses 2-3 times yearly. The...

GHK-Cu
Skin & Connective Tissue

GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma that declines sharply with age. It stimulates collagen and elastin synthesis, promotes wound healing, and activates anti-inflammatory gene expression pathways. Among the most-studied peptides in derma...
