GHK-Cu Reconstitution & Dosing
Also known as: Copper peptide
Quick answer: mix a 50 mg vial of GHK-Cu with 5 ml of bacteriostatic water. That gives 10.00 mg/ml, so a typical 1 mg dose is 10 units on a U-100 insulin syringe — about 50 doses per vial. Reported protocols range 1 mg–2 mg, daily.
GHK-Cu is a naturally occurring copper-binding tripeptide studied for skin remodeling, collagen synthesis and wound healing. It is used both as a subcutaneous injection and in topical cosmetic formulations. Full overview: what is GHK-Cu? →

FAQ
How much bacteriostatic water do you add to GHK-Cu?+
Most protocols mix a 50 mg vial of GHK-Cu with 5 ml of bacteriostatic water. This gives 10.00 mg/ml, so a typical 1 mg dose is 10 units on a U-100 insulin syringe. More or less water is fine — it only changes the volume you draw, not the dose.
What is a typical GHK-Cu dose?+
Commonly reported GHK-Cu protocols use 1 mg to 2 mg, daily, administered via subcutaneous or topical. These are reference figures from published protocols, not medical advice — individual use should be guided by a healthcare provider.
How many doses are in a 50 mg vial of GHK-Cu?+
At 1 mg per dose, a 50 mg vial contains about 50 doses, regardless of how much water you add.
How should GHK-Cu be stored?+
Reconstituted: refrigerate. Solution is naturally blue from the copper complex.
