Ipamorelin Calculator

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 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 .

Ipamorelin is a synthetic pentapeptide belonging to the growth hormone releasing peptide (GHRP) class. Published research has studied its agonism at the ghrelin / growth hormone secretagogue receptor (GHSR) and its effect on pulsatile growth hormone release. It has been characterized in the literature as more selective than earlier GHRPs such as GHRP-6 and GHRP-2 because it has shown minimal effect on cortisol and prolactin in reported studies. Ipamorelin is not approved by the FDA for human use. Research-grade ipamorelin sold by chemical supply companies is labeled for laboratory research purposes only.

How to reconstitute Ipamorelin

Research vendors typically offer ipamorelin in 2 mg, 5 mg, or 10 mg lyophilized vials. Reconstitution with 2–3 mL of bacteriostatic water is commonly reported.

Reconstituting Ipamorelin is the same unit-conversion process used for any lyophilized peptide:

1. Draw your chosen volume of bacteriostatic water into a syringe.
2. Inject the bacteriostatic water slowly down the side of the Ipamorelin vial — do not shoot it directly onto the powder.
3. Swirl gently until the powder fully dissolves. Do not shake.
4. Store the reconstituted vial refrigerated.
5. 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

Most Ipamorelin draw errors are unit errors, not arithmetic errors: confusing mg with mcg (1 mg = 1,000 mcg), or reading a U-40 syringe with U-100 math — the same printed mark holds 2.5× the volume. Two more worth avoiding: leaving the vial unlabeled, so the concentration and reconstitution date are lost, and under-diluting to the point where the draw is under about one unit and can no longer be read accurately.

Each of these is covered in full in the guides: reconstitution math from first principles, U-100 vs U-40 syringes, storage and shelf life, and how to reconstitute peptides.

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.
