Mechanism of ActionGHK-Cu stimulates collagen and elastin synthesis, promotes glycosaminoglycan production, supports blood vessel growth, and has antioxidant and anti-inflammatory properties. It remodels damaged tissue and activates wound-healing genes.Epithalon stimulates telomerase production, potentially slowing or reversing telomere shortening. It may also regulate melatonin production by the pineal gland and has been shown to influence gene expression related to aging.

Possible Side Effects
May vary by individual
  • Generally well-tolerated
  • Topical: mild skin irritation, redness, or tingling
  • Injectable: injection site reactions
  • May trigger histamine release - use caution with MCAS or histamine sensitivity
  • Risk of copper toxicity with excessive use
  • +2 more
  • Generally well-tolerated
  • Injection site reactions
  • Mild headache (transient)
  • Sleep disturbances
  • Risk of immunogenicity
  • +1 more
Research SummaryStudies demonstrate increased collagen synthesis, improved skin elasticity, reduced fine lines, and accelerated wound healing. Research shows it can reset gene expression to a healthier state and may have systemic anti-aging effects beyond skin.Russian studies show increased telomerase activity and extended lifespan in animal models. Human studies suggest improved sleep, reduced cortisol, and potential immune benefits. Research quality and Western replication remains limited.

Frequently Asked Questions: GHK-Cu vs Epithalon

What is the difference between GHK-Cu and Epithalon?
