Collagen and elastin synthesis, skin firmness, tissue regeneration. The human clinical evidence is TOPICAL, not injected.
Improved skin firmness, elasticity, and collagen production; reduced fine lines/wrinkles; better wound healing; clearer skin tone; sometimes thicker hair or faster tissue recovery.
The one randomised trial behind it was TOPICAL, on diabetic foot ulcers, in 1994, and it has never been replicated. The best-controlled cosmetic trial (Miller 2006, after laser resurfacing) was negative on every objective endpoint and positive only on a patient satisfaction questionnaire. The systemic subcutaneous use is community convention with no trial behind it.
No reference figure is given here. There is no personal reference on file for this compound, and we would rather leave it blank than fill it with a guess. The GHK-Cu calculator will do the arithmetic for any amount you enter.
| GHK-Cu | 1 mL water | 2 mL water | 3 mL water | 5 mL water |
|---|---|---|---|---|
| 50 mg vial | 50,000 mcg/mL | 25,000 mcg/mL | 16,667 mcg/mL | 10,000 mcg/mL |
| One unit (0.01 mL) | 500 mcg | 250 mcg | 167 mcg | 100 mcg |
Concentration = vial contents ÷ water added. It is the same compound at every volume — more water only means a weaker solution, larger syringe marks that are easier to read, and a larger injection volume. On a standard U-100 insulin syringe, one unit is 0.01 mL at any barrel size.
Education only. This page is educational. Most compounds referenced are not approved for human use, and a "research use only" label carries no legal status of its own.
Reported, not established. Any figure shown is a reported personal reference at the reconstitution stated — not a community average, not a clinical dose, and not necessarily right for anyone else's body, goals, or product.
Blank is deliberate. Where no figure appears, there is no personal reference to give. We would rather say nothing than imply confidence that isn't there.
Not medical advice. Nothing here constitutes medical advice, diagnosis, or treatment. Several of these are prescription medicines in Canada and the US, and several are approved nowhere at all. Consult a qualified healthcare professional before beginning any protocol.
