Avail. Notes
Russian joint/cartilage peptide bioregulator (Khavinson Institute). Not FDA-approved. Not on any FDA list. Research chemical in US.
Two distinct regulatory tracks. Topical GHK-Cu is widely used as a cosmetic ingredient (reviewed by the Cosmetic Ingredient Review panel as safe as used in cosmetics) and is available over the counter. Injectable/compounded GHK-Cu was placed on the interim FDA 503A "Category 2" list (significant safety risks) in September 2023; the FDA removed it from Category 2 in April 2026 after the nomination was withdrawn — this does not authorize compounding, and it is not on the 503A bulks list. GHK-Cu is not FDA-approved as a drug in any form.

About GHK-Cu

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.

Safety Profile

Information below reflects published research data only — not medical advice. Consult a qualified provider before use.

Cartalax

No established clinical contraindications. This is an investigational compound with limited human data and has not been evaluated by the FDA for safety in this context. Consult a qualified clinician.

GHK-Cu

No established clinical contraindications. This is an investigational compound with limited human data and has not been evaluated by the FDA for safety in this context. Consult a qualified clinician.

Used Together?

GHK-Cu

  • BPC-157

    Research suggests GHK-Cu and BPC-157 may produce complementary tissue repair and anti-inflammatory effects when combined. GHK-Cu is studied for copper-dependent collagen synthesis and antioxidant gene activation, while BPC-157 supports angiogenesis and growth factor expression.

  • Epithalon

    Research suggests Epithalon and GHK-Cu may produce complementary longevity-associated effects when combined. Epithalon is studied for telomere maintenance and pineal function, while GHK-Cu is studied for antioxidant gene expression and tissue remodeling — different mechanisms in aging research.
