Ipamorelin is a synthetic five-amino-acid peptide that acts on the ghrelin receptor to trigger growth hormone release. It is not FDA approved.
Ipamorelin powder vials are usually labeled 2 mg, 5 mg or 10 mg.
Here is the math for a 5 mg vial mixed with 2.5 mL of bacteriostatic water, drawing 200 mcg with a U-100 insulin syringe (1 mL = 100 units).
5 mg ÷ 2.5 mL = 2 mg/mL200 mcg ÷ 2 mg/mL = 0.1 mL0.1 mL × 100 = 10 units| Amount | Volume | U-100 syringe |
|---|---|---|
| 100 mcg | 0.05 mL | 5 units |
| 200 mcg | 0.1 mL | 10 units |
| 400 mcg | 0.2 mL | 20 units |
Adding more water doesn't change how much ipamorelin is in the vial. It only spreads it over more liquid, so each draw is bigger and easier to read.
| Water added | Concentration | Volume | U-100 syringe |
|---|---|---|---|
| 2 mL | 2.5 mg/mL | 0.08 mL | 8 units |
| 2.5 mL | 2 mg/mL | 0.1 mL | 10 units |
| 3 mL | 1.67 mg/mL | 0.12 mL | 12 units |
| 5 mL | 1 mg/mL | 0.2 mL | 20 units |
For any other vial size or amount, the free peptide reconstitution calculator works backwards from the amount you want and suggests a water volume that lands on a clean syringe mark.
A human study (Gobburu 1999) found a terminal half-life of about 2 hours. That study gave ipamorelin into a vein, so it reports no time to peak for an injection under the skin, and we leave that out.
Numbers shown are the values Dose Track uses, listed only where they agree with the source above. Half-life varies from person to person and with injection site.
