Ipamorelin Dosage Calculator

A selective growth hormone secretagogue (ghrelin receptor agonist), often paired with CJC-1295. Enter your vial size, the water you add, and your dose to see the units to draw. Defaults: 5 mg vial, 2 mL water, 200 mcg per dose.

Math only. The dose itself comes from your prescriber or protocol; this page does not recommend one.

How to reconstitute Ipamorelin

Ipamorelin is sold as a freeze-dried powder, most often in 2 mg, 5 mg, 10 mg vials. Add bacteriostatic water, let it dissolve without shaking, and the concentration is the vial amount divided by the water: 5 mg in 2 mL is 2.5 mg/mL. On a U-100 insulin syringe one unit is 0.01 mL, so each unit carries 25 mcg, and a 200 mcg dose is 8 units.

Not approved for human use. Commonly cited: 100 to 300 mcg per injection, one to three times a day. Nothing on this page is a dosing recommendation; the calculator converts a dose you already have into syringe units.

The dose column is in mcg. Doubling the water halves the concentration and doubles the units per dose; the number of doses in the vial never changes. If a dose comes out under 5 units, use less water so it is easier to measure. If it exceeds the syringe, use more water or a bigger syringe.

Worked example

5 mg / 2 mL = 2.5 mg/mL = 2,500 mcg/mL. One unit = 0.01 mL = 25 mcg. 200 mcg / 25 mcg per unit = 8 units. The vial holds 5,000 / 200 = 25 doses, which at 7 per week is about 25 days.

Frequently asked questions

How many units is 200 mcg of Ipamorelin?

With 5 mg in 2 mL of bacteriostatic water the concentration is 2.5 mg/mL, each unit holds 25 mcg, and 200 mcg is 8 units (0.08 mL). Change the water and the units change with it.

How much bacteriostatic water do I add to a 5 mg vial of Ipamorelin?

Any volume gives the same doses; 2 mL is a common choice because it keeps 200 mcg at 8 units, which is easy to read on an insulin syringe. Use the calculator's round-number table to pick a volume that fits your syringe.

How long does a 5 mg vial of Ipamorelin last?

At 200 mcg per dose the vial holds 25 doses. At 7 doses a week that is about 25 days. Reconstituted vials are usually refrigerated and used within about four weeks.

What is the Ipamorelin dose?

Not approved for human use. Commonly cited: 100 to 300 mcg per injection, one to three times a day. This calculator only converts a dose you already have into syringe units.
