Cartalax vs GHK-Cu

Tetrapeptide bioregulator from cartilage tissue; stimulates chondrocyte proliferation and extracellular matrix synthesis; normalizes gene expression in cartilage cells

A Khavinson peptide bioregulator targeting cartilage tissue. Promotes chondrocyte activity and cartilage matrix regeneration; studied for osteoarthritis and joint degeneration.

GHK-Cu promotes the synthesis of collagen, elastin, glycosaminoglycans, and decorin, contributing to tissue remodelling and wound contraction. It modulates the activity of matrix metalloproteinases (MMPs) — stimulating wound-healing MMPs while suppressing those that degrade healthy tissue. Genomic analysis has identified GHK-Cu as a modulator of over 4,000 genes, including those governing antioxidant defences and anti-inflammatory pathways.

GHK-Cu (copper peptide tripeptide-1) is a naturally occurring plasma copper complex with broad tissue-remodelling activity. It is one of the most extensively researched peptides for skin health, wound healing, and collagen synthesis. Research has explored its effects across dermatological, cosmetic, and systemic contexts, including roles in joint tissue maintenance and anti-inflammatory signalling.
