What is GHK-Cu?
GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine complexed with a copper(II) ion. It occurs naturally in plasma and declines with age, and it is studied for its role in collagen synthesis, wound remodelling, antioxidant enzyme expression and gene-expression changes associated with tissue repair. Pepstral supplies GHK-Cu as a lyophilized powder, 50 mg per vial, with the copper complex confirmed by LC-MS on every lot.

What is GHK-Cu studied for?
- Collagen and elastin synthesis in fibroblast models
- Wound remodelling and skin-barrier studies
- Antioxidant and anti-inflammatory gene-expression assays
- Hair-follicle and dermal papilla research
All applications above are in-vitro or preclinical research contexts. GHK-Cu is sold for laboratory research only and is not for human or animal use.
What does the certificate for lot GHK50-0803 show?
Every lot of GHK-Cu is tested by an independent US laboratory before it is listed. The report for lot GHK50-0803 is in the COA library and the lot number printed on the vial matches it. The current results:
| Test | Method | Lot GHK50-0803 result |
|---|---|---|
| Identity | LC-MS/MS | GHK-Cu · conforms |
| Content | HPLC quantitation | 51.02 mg |
| Purity | RP-HPLC (214 nm) | 99.77% |
| Endotoxin | USP <85> | <0.05 EU/mL |
| Heavy metals | USP <232> | <0.01 ppm |
How is GHK-Cu handled and stored?
Sealed vials are stored at -20°C away from light and keep for 24 months. To reconstitute, add bacteriostatic water slowly down the inside wall of the vial and swirl until clear; never shake. Once in solution, keep at 2 to 8°C and use within our 28-day default for a preserved solution. The concentration table gives the dilution volumes and microlitre aliquots for this vial.
Frequently asked questions
Is the copper included, or is this GHK alone?
The copper complex. LC-MS/MS on lot GHK50-0803 confirms the complexed mass, and the blue colour of the reconstituted solution is the visual check.
Why 50 mg rather than 5 or 10?
GHK-Cu is used at higher concentrations in dermal and fibroblast work than signalling peptides, so the vial is sized for those protocols.
What purity does the certificate report?
Lot GHK50-0803: 99.77% purity by RP-HPLC (214 nm), identity GHK-Cu confirmed by LC-MS/MS, content 51.02 mg by HPLC quantitation, endotoxin <0.05 EU/mL, heavy metals <0.01 ppm. Certificate COA7628, issued 17 August 2026 by Bioviridian Inc.
Is GHK-Cu for human use?
No. Every product on this site is sold for in-vitro laboratory research only and is not for human or animal consumption, diagnostic or therapeutic use.
Also ordered as part of longevity stack and repair plus.
