GHK-Cu Reconstitution Calculator
Reconstitute a 50 mg vial of GHK-Cu with 3 mL of bacteriostatic water for a concentration of 16.67 mg/mL — meaning one unit on a U-100 insulin syringe (0.01 mL) holds 167 mcg. Adjust the inputs below for your own vial and dose.

GHK-Cu mg-to-units quick reference
At the default 16.67 mg/mL (50 mg in 3 mL), draw the following units on a U-100 insulin syringe:
| Target dose | Volume | U-100 units |
|---|---|---|
| 250 mcg (0.25 mg) | 0.015 mL | 1.5 units |
| 500 mcg (0.50 mg) | 0.030 mL | 3.0 units |
| 1000 mcg (1.00 mg) | 0.060 mL | 6.0 units |
Frequently Asked Questions
How do I reconstitute GHK-Cu?expand_more
Add 3 mL of bacteriostatic water to the 50 mg GHK-Cu vial for a concentration of 16.67 mg/mL. Inject the water slowly down the vial wall and swirl gently — do not shake.
How many units is a GHK-Cu dose on an insulin syringe?expand_more
At 16.67 mg/mL, one unit on a U-100 syringe (0.01 mL) holds 167 mcg. Divide your target dose in mcg by 167 to get the number of units to draw.
What is the typical GHK-Cu research dose?expand_more
GHK-Cu is typically dosed at 1.0–2.0 mg per injection (most common protocols use 5 days/week or 3×/week). in research protocols. See the full titration schedule on the protocol page.
