What It Is
GHK-Cu binds copper(II) ions and delivers them to cells as a copper chaperone, activating numerous metalloenzymes including superoxide dismutase (SOD). It stimulates collagen, elastin, and glycosaminoglycan synthesis by upregulating TGF-beta and connective tissue growth factor (CTGF). It activates VEGF production to promote angiogenesis and wound healing. GHK-Cu modulates over 4,000 human genes according to transcriptome studies, with effects on antioxidant defense, anti-inflammatory pathways, and stem cell activation. It promotes nerve growth factor production and has neuroprotective properties.
Supplies Needed
Reconstitution solvent
Subcutaneous injection
Sterilization
Vehicle for topical GHK-Cu application to skin
Storage
Store at -20C for up to 2 years. Protect from light - copper complex can degrade with UV exposure.
Refrigerate at 2-8C; use within 30 days. Solution may be blue-green - this is normal.

Reconstitution Calculator
1 unit on U-100 syringe = 0.01 mL · Always label your vial after reconstitution
Injection Technique & Reconstitution
- Remove flip-top cap from the vial
- Swab rubber stopper with alcohol swab
- Draw appropriate volume of bacteriostatic water into syringe
- Inject slowly down the vial wall - solution may appear blue-green from copper complex
- Gently swirl until dissolved
- Label with reconstitution date; refrigerate at 2-8C

Combined regenerative and collagen synthesis effects - BPC-157 drives tissue repair signaling while GHK-Cu directly stimulates collagen and elastin production.
Triple healing stack with BPC-157 - TB-500 provides systemic angiogenesis, BPC-157 local tissue repair, and GHK-Cu collagen remodeling.
Anti-aging stack - Epithalon targets cellular longevity via telomere biology while GHK-Cu provides tissue-level regeneration and antioxidant protection.
Frequently Asked Questions
GHK-Cu is used for wound healing, skin anti-aging, collagen stimulation, hair growth, and as a systemic regenerative peptide. It occurs naturally in the body but declines with age.
Yes - GHK-Cu at 3% concentration in topical formulations effectively penetrates the epidermis and stimulates collagen synthesis, reduces wrinkles, and improves skin quality. Many skincare products contain GHK-Cu for this reason.
Yes - the blue-green color comes from the copper(II) complex. This is normal and indicates the peptide is properly formed. A clear solution may indicate the copper has been lost from the complex.
