GHK-Cu

GHK-Cu

Also known as: Copper Peptide, GHK Copper, Tripeptide-1 Copper

Overview

Key Facts

Primary Goal: Research and therapeutic applications of GHK-Cu

Delivers bioavailable copper to activate lysyl oxidase for collagen crosslinking. Upregulates TGF-beta signaling to promote extracellular matrix remodeling.

Dosing Information

Half-Life

~1-2 hours (injectable); variable topically

Typical Dose

0.5–3 mg

Frequency

Once daily (topical or injection)

Cycle Length

4-8 weeks on, 2-4 weeks off

Administration Routes:
subcutaneoustopical

Benefits

  • Stimulates collagen I, III and elastin synthesis
  • Reduces fine lines, wrinkles, and photodamage
  • Improves skin firmness, thickness, and clarity
  • Accelerates wound healing and scar remodeling
  • Promotes hair growth and follicle enlargement
  • Reduces hyperpigmentation and age spots

Side Effects

Mild skin irritation or redness at application sitemild
Transient warmth at injection sitemild
Rare allergic reaction in copper-sensitive individualsmild

Mechanism of Action

1

Delivers bioavailable copper to activate lysyl oxidase for collagen crosslinking

2

Research Summary

Preclinical
100 studies

Discovered by Dr. Loren Pickart in the 1970s, GHK-Cu has over 100 published studies. Broad Institute Connectivity Map data showed it modulates expression of ~32% of human genes, reversing many age-related expression patterns. Clinical trials demonstrate increased collagen synthesis, improved skin density, and reduced wrinkle depth. It is the most widely adopted peptide in cosmeceutical formulations worldwide.
