GHK-Cu dose guide

A peptide dosage chart, one peptide at a time: its dose range, how often it’s taken, a typical run and the units on your syringe. All 69 peptides in the PepVault library.

A community reference, not medical advice. Each range is what has been studied or is commonly run, never a dose for you.

GHK-Cu dosage

A small copper-binding peptide found naturally in your blood and widely used in skincare. In cell and animal studies it boosts collagen production and speeds wound repair, and in a controlled skin trial a GHK-Cu serum cut wrinkle volume more than a control serum. Commonly reported: smoother texture and a more even tone after a month or two. Injected GHK-Cu hasn't been tested in a controlled trial.

Dose range
1–2 mg (research range). Studied in research — not a recommendation.
How often
Daily
A typical run
8–12 weeks. Often run 8–12 weeks. Can be cycled or run continuously at lower doses. Community consensus is loose.
How it’s taken
Vial: SubQ injection, Topical application, IM injection
Evidence
Emerging: Primarily preclinical / limited human data
Half-life
Not measured in humans (breaks down quickly in plasma in rat and lab studies)

GHK-Cu on your syringe

With a 10 mg vial and 2 mL of water (5 mg in every mL), on a 0.5 mL (50-unit) U-100 insulin syringe: the low end, 1 mg, is 20 units; and the high end, 2 mg, is 40 units. 10 doses in the vial at the low end. All U-100: 100 units to the mL. A U-40 syringe reads differently.
