About GHK-Cu dosing

GHK-Cu vials are large (50 to 100 mg), so the concentration is high and small changes in water make a big difference in units. The mixed solution is naturally blue.

Typical research use is 1 to 2 mg daily under the skin for 4 to 8 weeks. It can sting at the injection site, so some people add more water to dilute it.

Step by step

Reconstitution steps

Every step below uses the numbers you entered above.

  1. 1
    Wipe both stoppers

    Swab the rubber tops of the 50 mg GHK-Cu vial and the bacteriostatic water vial with fresh alcohol pads. Let them air dry for a few seconds.

  2. 2
    Draw 3 mL of BAC water

    Pull 3 mL of bacteriostatic water into a reconstitution syringe (usually a 3 mL syringe with a 21g needle).

  3. 3
    Add water slowly, down the side

    Inject the water against the inside wall of the vial, don't blast it directly onto the powder. This protects the peptide from shear damage.

  4. 4
    Swirl, don't shake

    Gently swirl until the powder is fully dissolved and the liquid is clear. Never shake, foaming denatures the peptide.

  5. 5
    Draw 12 units on a 1 mL syringe

    On your 100-unit (1 mL) insulin syringe, pull the plunger back until the rubber tip lines up with 12, that's your 2.00 mg dose. Tap out any air bubbles, then inject as directed.

  6. 6
    Store refrigerated

    Cap the vial and store at 2–8 °C (36–46 °F). Most reconstituted peptides remain stable for 3–4 weeks refrigerated.

Frequently asked questions

How many units is 2 mg of GHK-Cu?

With a 50 mg vial and 3 mL of water (16.67 mg/mL), 2 mg is 0.12 mL, which is 12 units.

How much water for a 50 mg GHK-Cu vial?

3 to 5 mL is common. More water means less sting and easier measuring.

Why does GHK-Cu sting?

Copper peptides can irritate tissue at high concentration. Diluting with more water and rotating sites helps.

Is GHK-Cu supposed to be blue?

Yes. The copper gives the mixed solution a blue color.
