GHK-Cu reconstitution calculator
GHK-Cu ships as 50 mg, 100 mg vials of lyophilized powder. Pick the size, type the water volume, read the concentration. The molecular weight is already filled in, so the molar result is there too.

Concentration = peptide mass ÷ diluent volume. Molarity = (mg/mL ÷ g/mol) × 1000. Research use only.

What the numbers mean for GHK-Cu
GHK-Cu has a molecular weight of 403.91 g/mol (C14H22CuN6O4). So 50 mg is about 124 micromoles, whatever volume you dissolve it in. At 25 mg/mL that is 61.9 mM.
Sequence: GHK (copper complex). The expected mass on the vial's mass-spec result is the molecular weight above; a match within a tenth of a percent is the identity check passing.
Each vial holds only powder, from 50 mg up to 100 mg, and no diluent. Add bacteriostatic water down the inside of the glass, swirl, and do not shake. The reconstitution guide covers the handling; this page covers the arithmetic.
Common questions
How much water do I add to a 50 mg vial of GHK-Cu?
+
Any volume that gives a concentration you can measure easily. 1 mL gives 50 mg/mL, 2 mL gives 25 mg/mL, 5 mL gives 10 mg/mL. The peptide amount stays 50 mg whatever you add.
What is the concentration of GHK-Cu 50 mg in 2 mL?
+
25 mg/mL, which is the same as 25 µg/µL. With a molecular weight of 403.91 g/mol that is 61.9 mM.
Which GHK-Cu vial sizes does the calculator cover?
+
The ones we sell: 50 mg, 100 mg. Pick a chip or type any other mass.
Where does the GHK-Cu molecular weight come from?
+
The reference value on the product's Specifications tab, 403.91 g/mol. The observed mass for the vial you receive is on its own lab report, which the QR code on the vial opens.
