GHRP-2 Reconstitution

How to reconstitute GHRP-2

1. Swab the rubber stopper of the GHRP-2 vial and the bacteriostatic water vial with an alcohol wipe.
2. Draw 2 ml of bacteriostatic water into a syringe.
3. Inject it slowly down the inside wall of the GHRP-2 vial, not directly onto the powder.
4. Swirl gently until the powder fully dissolves. Do not shake. Shaking can damage the peptide.
5. Keep the unreconstituted vial at 2 to 8 degrees C.

GHRP-2 concentration by water volume

GHRP-2 is commonly supplied in 5 mg vials. The concentration depends only on how much bacteriostatic water you add. More water lowers the concentration and makes small doses easier to measure.

GHRP-2 units to draw

At 2,500 mcg/ml (a 5 mg vial in 2 ml of bacteriostatic water), here is the draw for doses across the range GHRP-2 is typically used at. Change any number in the calculator above for your own vial.

GHRP-2 dosing

There is no approved dose for these uses. Community and clinic protocols commonly reference roughly 100 to 300 mcg subcutaneously, once to a few times per day, often before sleep or around training. These numbers come from practice and early research, not from modern dose-finding trials, so treat them as convention rather than validated medicine. Enter your own vial size, water volume, and target dose in the calculator above to convert any GHRP-2 protocol into exact insulin-syringe units. For the full profile, see the GHRP-2 compound page.

Storing reconstituted GHRP-2

Keep the unreconstituted vial at 2 to 8 degrees C. Once mixed, refrigerate and protect from light. No published in-use stability data exists.

Human data is limited to acute single-dose GH-provocation testing at around 1 mcg/kg, roughly 70 to 100 mcg for a 70 kg adult. There is no chronic-use dosing evidence, and the 100 to 300 mcg protocols in circulation are community convention. GHRP-2 also elevates prolactin and cortisol.

The dose range above comes from published clinical trials. GHRP-2 is not FDA-approved for this use.

The math

• Concentration (mcg/ml) = vial size in mg × 1,000 ÷ bacteriostatic water in ml.
• Volume for your dose (ml) = dose in mcg ÷ concentration.
• Units to draw = volume in ml × 100 on a U-100 insulin syringe.
