GHK-CU
Preclinical — Animal / cell-model data onlyWhat it is
A naturally occurring copper-binding tripeptide. The best-evidenced compound in this catalogue, but that evidence is topical and cosmetic.
GHK-Cu is a naturally occurring copper-binding tripeptide and the best-evidenced compound in this catalogue — though that evidence is topical/cosmetic (skin repair, collagen, hair). Injectable use is far less studied.
Research context
Studied in relation to:
- Collagen & skin repair (topical)
- Wound healing
- Hair follicle support
Points in its favour in the literature:
- Solid published topical/cosmetic evidence
- Naturally present in the body
- Widely used in skincare
Caveats and unknowns:
- Injectable use far less studied than topical
- Can irritate some users
- Copper load a concern at high exposure
Handling & reference data
Route in published researchTopical is the best-evidenced route; subcutaneous is used in research.
Published clinical / research context (not instructions)Topical cosmetic formulas ~0.05–2%. Injectable research amounts ~1–2 mg, often once daily.
Storage (lyophilised)Lyophilised (freeze-dried) powder: refrigerate at 2–8 °C short-term, or freeze at −20 °C or below for long-term storage. Keep sealed and out of light.
Reconstituted solutionOnce reconstituted: keep refrigerated (2–8 °C), protect from light, do not freeze. With bacteriostatic water, commonly used within ~4 weeks; with plain sterile water, within ~24–48 h.
Worked reconstitution example (arithmetic only)e.g. 50 mg vial + 5 mL → 10 mg/mL (10,000 mcg/mL).
