GHK-Cu Dosage Calculator
Reconstitution volumes, concentration and U-100 unit equivalents for GHK-Cu.
These examples explain unit relationships in published research and are not instructions for preparing, measuring or administering any compound. Do not use this information to self-administer research chemicals.
Worked at 2.00 mg, the amount reported in the research for GHK-Cu. Every row is the same arithmetic: milligrams in the vial divided by millilitres of water gives the concentration, and the target amount divided by that concentration gives the volume.

Suppliers are listed alphabetically. We do not rank them by price, because the cheapest vial and the one worth buying are rarely the same thing. The column that matters is the last one, and today most of it reads "none on file", including for Quartz Peptides, which is owned by this site’s editor. See the disclosure and the COA guide.
How strong is the evidence for GHK-Cu?
We grade it C on a four-point scale. The strong evidence is topical. Controlled injectable trials are lacking.
What is the half-life of GHK-Cu?
It is not well characterized in humans. Published pharmacokinetic data for GHK-Cu is thin, so any specific figure you see quoted should be treated with caution.
What amount of GHK-Cu is used in the research?
Ongoing: 1–2 mg daily. The strong evidence is topical; injectable amounts reflect reference practice only.
How much does GHK-Cu cost?
A 50 mg vial lists at $43 from Quartz Peptides, which works out to $0.86 per mg and about $1.29 per dose at the amount used in research. Prices checked September 4, 2026. Price is not a quality signal, so check the certificate of analysis before ordering from anyone.
How is GHK-Cu stored once reconstituted?
Refrigerate the mixed vial at 2 to 8 °C, use within a few weeks and avoid freeze and thaw.
