GHK-Cu peptide calculator
Pre-filled GHK-Cu dosage and reconstitution math: a 50 mg vial, 5 ml of bacteriostatic water, and the resulting U-100 insulin-syringe units. Adjust the inputs below or open the full calculator.
How to reconstitute GHK-Cu
- Wipe both vial stoppers with a fresh alcohol swab and let them dry.
- Draw 5 ml of bacteriostatic water into a syringe.
- Insert the needle at an angle into the GHK-Cu vial and let the water run slowly down the inner wall — do not inject directly onto the powder.
- Do not shake. Gently swirl the vial until the peptide fully dissolves.
- Store the reconstituted vial refrigerated (2–8 °C / 36–46 °F) and use within roughly 28 days.
- Draw each dose to the unit mark shown above for your target 2000 mcg dose.
About GHK-Cu
GHK-Cu is a naturally occurring copper-binding tripeptide with well-studied effects on collagen synthesis, wound healing, and hair follicle stimulation. Widely used topically; injectable use is research-only.
Half-life: Approximately 0.5–1 hour systemically
Typical dose range: 1–3 mg per injection; topical concentrations vary
Class: Copper-binding tripeptide
GHK-Cu calculator FAQ
Is this a GHK-Cu peptide calculator or a reconstitution calculator?
Both. This GHK-Cu calculator converts vial strength, bacteriostatic-water volume, and target dose into milliliters and insulin-syringe units. It does not recommend a medical dose.
How much bacteriostatic water for a 50 mg GHK-Cu vial?
This page is pre-filled with 5 ml of bacteriostatic water for a 50 mg GHK-Cu vial because that is a common research ratio. You can adjust the water amount in the full calculator.
How many units is a 2000 mcg GHK-Cu dose?
With the default 50 mg vial and 5 ml BAC-water ratio, the preview above calculates the U-100 syringe units for a 2000 mcg dose. Change the dose if your protocol uses a different amount.
Does this GHK-Cu dosage calculator give medical advice?
No. It only performs unit math. Dosing, titration, and whether GHK-Cu is appropriate are clinical decisions that should be made with a licensed healthcare professional.
