GHRP-2 reconstitution calculator

GHRP-2 ships as a 5 mg vial 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 GHRP-2

GHRP-2 has a molecular weight of 817.96 g/mol (C45H55N9O6). So 5 mg is about 6.11 micromoles, whatever volume you dissolve it in. At 2.5 mg/mL that is 3.06 mM.

The vial holds 5 mg of powder 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 5 mg vial of GHRP-2?+

Any volume that gives a concentration you can measure easily. 1 mL gives 5 mg/mL, 2 mL gives 2.5 mg/mL, 5 mL gives 1 mg/mL. The peptide amount stays 5 mg whatever you add.

What is the concentration of GHRP-2 5 mg in 2 mL?+

2.5 mg/mL, which is the same as 2.5 µg/µL. With a molecular weight of 817.96 g/mol that is 3.06 mM.

Where does the GHRP-2 molecular weight come from?+

The reference value on the product's Specifications tab, 817.96 g/mol. The observed mass for the vial you receive is on its own lab report, which the QR code on the vial opens.
