Ipamorelin dosage calculator
The Ipamorelin 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. Ipamorelin is commonly sold in 2 mg, 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 selective pentapeptide growth hormone releasing peptide that activates the ghrelin receptor to stimulate pituitary GH release. Enter your target dose in the calculator above to see the exact number of units to draw.
Ipamorelin dosage chart
| Sample dose | Concentration | Volume to draw | Units on U-100 |
|---|---|---|---|
| 130 mcg | 2.5 mg/mL | 0.052 mL | 5.2 |
| 250 mcg | 2.5 mg/mL | 0.1 mL | 10 |
| 500 mcg | 2.5 mg/mL | 0.2 mL | 20 |
| 1000 mcg | 2.5 mg/mL | 0.4 mL | 40 |
| 2000 mcg | 2.5 mg/mL | 0.8 mL | 80 |
Ipamorelin and GHRP peptides
Ipamorelin is a Pentapeptide growth hormone releasing peptide (GHRP). A selective pentapeptide growth hormone releasing peptide that activates the ghrelin receptor to stimulate pituitary GH release. Other peptides in the GHRP class include Hexarelin .
How to reconstitute Ipamorelin
Reconstituting Ipamorelin 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 Ipamorelin 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 Ipamorelin specifically, 2 mg, 5 mg, 10 mg vials are common. A typical reconstitution adds 2 mL of bacteriostatic water, producing a concentration of 2.5 mg/mL for the 5 mg vial size.
Ipamorelin half-life and storage
Published pharmacokinetic studies report a plasma half-life of approximately 2 hours for ipamorelin.
Lyophilized ipamorelin is typically stored refrigerated at 2–8 °C. Reconstituted solutions are generally kept refrigerated and protected from light.
Common Ipamorelin 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.
Ipamorelin stacks
Ipamorelin is one of the ingredients in what is commonly referred to as the GH stack . These are terms used in online peptide communities to describe specific combinations. See the stack pages for the full composition and calculator links.
