GHK-Cu Calculator
Copper tripeptide
Reconstitution math and daily dose volume for skin and tissue remodeling
GHK-Cu is a copper-bound tripeptide commonly dosed at 1 mg subcutaneously daily for skin remodeling, hair, and tissue repair protocols. Vials are typically 50 mg, so a single vial lasts roughly 50 days at 1 mg per dose. The calculator below converts your vial size, water volume, and dose into the exact draw line on a U-100 insulin syringe.

Interactive GHK-Cu reconstitution and dose calculator
Worked example — GHK-Cu 1 mg dose
A typical reconstitution and dose calculation for GHK-Cu, with every variable spelled out. The calculator above runs the same math live as you change inputs.
- Vial strength
- 50 mg
- Bacteriostatic water
- 5 mL
- Concentration
- 10.00 mg/mL
- Dose volume
- 0.1 mL · 10 units
A 50 mg GHK-Cu vial reconstituted with 5 mL of bacteriostatic water yields 10 mg/mL. A 1 mg dose is 0.10 mL — 10 units on a U-100 insulin syringe. The high concentration keeps daily injection volumes small and easy to read on a 0.3 mL or 0.5 mL syringe.
