GHK-Cu reconstitution calculator
Naturally occurring copper tripeptide. Almost all clinical evidence is topical; subcutaneous dosing is not established in human trials and the SC range below is extrapolated from anecdotal protocols. In cultured fibroblasts, GHK-Cu raised collagen type 1 expression (Maquart/Pickart, FEBS Lett 1988, PMID 3169264). Studied for skin remodeling, wound healing, and hair growth.

Frequently asked questions
How much bacteriostatic water should I add to GHK-Cu?
For a 5mg vial of GHK-Cu, add 2ml of bacteriostatic water. This concentration works well with a standard insulin syringe.
What is the typical GHK-Cu dosage?
Typical research dosages for GHK-Cu range from 200 to 600 mcg, administered 1x daily.
How long does reconstituted GHK-Cu last?
Reconstituted GHK-Cu should be stored at 2-8°C refrigerated and used within 21 days. Unreconstituted vials can be stored for up to 24 months.
How do I calculate my GHK-Cu dose?
Divide your target dose by the concentration to get the volume, then multiply by 100 for units on a U-100 insulin syringe. For example, a 5mg vial in 2ml of bacteriostatic water gives 2500 mcg/ml. The calculator above does this automatically once you enter your vial size, water volume, and desired dose.
How many units of GHK-Cu should I draw on an insulin syringe?
On a U-100 insulin syringe, 1 unit equals 0.01 ml regardless of the barrel size (0.3ml, 0.5ml, or 1ml). Enter your reconstitution details in the calculator to see the exact number of units to draw for your dose.
