Epithalon vs GHK-Cu

Epithalon vs GHK-Cu: two longevity-focused peptides with different mechanisms. Epithalon targets telomere elongation and pineal function; GHK-Cu targets gene expression, collagen synthesis, and wound healing.

Mechanism Comparison

Epithalon: activates telomerase, elongates telomeres, normalizes melatonin secretion, modulates neuroendocrine function. GHK-Cu: binds copper, modulates 4,000+ genes, upregulates collagen/elastin synthesis, activates ubiquitin-proteasome pathway.

Research Applications

Epithalon: longevity research, telomere biology, circadian rhythm normalization, anti-aging protocols. GHK-Cu: skin research (topical), wound healing, anti-inflammatory research, lung tissue repair (COPD models).

Combination Protocol

Epithalon and GHK-Cu target different mechanisms and can be combined. Common protocol: Epithalon 10 mg/day × 10 days (2x/year) + GHK-Cu topical daily or subcutaneous 2–3x/week for systemic effects.
