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.Combines Pal-GHK (collagen synthesis) with Pal-GQPR (anti-inflammatory). The dual action stimulates new collagen production while reducing inflammation that accelerates aging. Works synergistically with better results than either peptide alone.

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 very well-tolerated
  • Temporary stinging (first week)
  • May trigger breakouts in acne-prone skin
  • Avoid mixing with strong acids
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.Studies show superior wrinkle reduction compared to original Matrixyl. Research demonstrates reduced inflammatory markers along with increased collagen. Clinical trials show improvement in skin firmness and elasticity.

Frequently Asked Questions: GHK-Cu vs Matrixyl 3000

What is the difference between GHK-Cu and Matrixyl 3000?
