GHRP-6 dosage calculator
The GHRP-6 dosage calculator above converts a target dose into exact syringe units based on your vial size and how much bacteriostatic water you used to reconstitute it. GHRP-6 is commonly sold in 5 mg, 10 mg vials. The calculator supports both U-100 and U-40 insulin syringes and flags draws that are too large for the syringe barrel or too small to measure accurately. A growth hormone releasing peptide that activates the ghrelin receptor and has been characterized for orexigenic activity. Enter your target dose in the calculator above to see the exact number of units to draw.
GHRP-6 dosage chart
| Sample dose | Concentration | Volume to draw | Units on U-100 |
|---|---|---|---|
| 190 mcg | 2.5 mg/mL | 0.076 mL | 7.6 |
| 380 mcg | 2.5 mg/mL | 0.152 mL | 15.2 |
| 750 mcg | 2.5 mg/mL | 0.3 mL | 30 |
| 1500 mcg | 2.5 mg/mL | 0.6 mL | 60 |
| 3000 mcg | 2.5 mg/mL | 1.2 mL | 120 |
GHRP-6 and Orexigenic peptides
GHRP-6 is a Orexigenic growth hormone releasing peptide. A growth hormone releasing peptide that activates the ghrelin receptor and has been characterized for orexigenic activity.
How to reconstitute GHRP-6
Reconstituting GHRP-6 is the same unit-conversion process used for any lyophilized peptide:
- Draw your chosen volume of bacteriostatic water into a syringe.
- Inject the bacteriostatic water slowly down the side of the GHRP-6 vial — do not shoot it directly onto the powder.
- Swirl gently until the powder fully dissolves. Do not shake.
- Store the reconstituted vial refrigerated.
- To dose, calculate your draw volume: divide your target dose by the concentration (vial mg ÷ water mL = mg/mL). The calculator above does this automatically.
For GHRP-6 specifically, 5 mg, 10 mg vials are common. A typical reconstitution adds 2 mL of bacteriostatic water, producing a concentration of 5 mg/mL for the 10 mg vial size.
GHRP-6 half-life and storage
Published pharmacokinetic data reports a plasma half-life of approximately 15–60 minutes for GHRP-6.
Lyophilized GHRP-6 is typically stored refrigerated at 2–8 °C. Reconstituted solutions are generally refrigerated and protected from light.
Common GHRP-6 dosing mistakes
- Confusing mg and mcg. 1 mg = 1,000 mcg. Always convert to the same unit before computing the draw.
- Using a U-40 syringe with U-100 math. Same printed mark, 2.5× the physical volume. Always check the syringe label.
- Not labeling the vial. Write the reconstitution date and concentration on the vial the moment you mix it.
- Under-diluting. If your draw is less than about 1 unit, the volume is too small to read accurately — add more bacteriostatic water next time.
