Peptide LibraryGHRP-6 calculator
GHRP-6 has been given to people as a single intravenous bolus dosed per kilogram of body weight, in a pharmacokinetic study and as a diagnostic stimulus in endocrine testing. It raises ACTH and cortisol as well as growth hormone, and no product is approved. Vials are 5 or 10 mg. The calculator does the vial arithmetic; the studied doses are listed below as reported, not converted.

GHRP-6 reconstitution chart
Concentration and micrograms per mark on a U-100 insulin syringe, by vial size and water added. The peptide amount never changes; only how concentrated it is.
| Vial | + 1 mL water | + 2 mL water | + 3 mL water |
|---|---|---|---|
| 5 mg | 5 mg/mL · 50 mcg per unit | 2.5 mg/mL · 25 mcg per unit | 1.67 mg/mL · 16.7 mcg per unit |
| 10 mg | 10 mg/mL · 100 mcg per unit | 5 mg/mL · 50 mcg per unit | 3.33 mg/mL · 33.3 mcg per unit |

Why the GHRP-6 study doses are not converted to units
The published human studies of GHRP-6 report doses per kilogram of body weight, not a fixed amount. Turning them into milligrams or syringe units would mean assuming a body weight, so this page lists them as reported and converts nothing. A fixed amount quoted elsewhere is not the same thing as a weight-based dose.

Common questions
How much bacteriostatic water do you add to a 5 mg GHRP-6 vial?
There is no single correct volume: the amount of peptide is fixed and the water only sets the concentration. For 5 mg, 1 mL gives 5 mg/mL (50 mcg per unit), 2 mL gives 2.5 mg/mL (25 mcg per unit) and 3 mL gives 1.67 mg/mL (16.7 mcg per unit). More water makes each syringe mark hold less, which makes small amounts easier to measure accurately.
What dose does the GHRP-6 calculator use?
None. The published human studies of GHRP-6 report doses per kilogram of body weight (100, 200 and 400 mcg/kg of body weight), so they are not a fixed amount, and the calculator does not turn them into one. It converts a vial size, a water volume and an amount you enter into a volume and syringe units; the tables on this page show concentrations only.
What does one unit on an insulin syringe mean?
A unit is a volume mark, not an amount of drug. On a U-100 syringe 100 units fill 1 mL, so 10 units is always 0.1 mL; how much peptide those 10 units hold depends only on the concentration you mixed. U-40 syringes use 40 marks per mL, so the same volume reads as a different number of units.
