Ipamorelin Reconstitution Calculator (mcg → units)
A 5 mg vial of Ipamorelin mixed with 2 mL of bacteriostatic water holds 2,500 mcg/mL, so a 200 mcg dose is 0.08 mL — 8 units on a U-100 insulin syringe. Change the vial, water or dose below, or read the chart for other mixes.
Ipamorelin dilution chart: 200 mcg in units
| Vial | + 1 mL water | + 2 mL water | + 3 mL water | Doses per vial |
|---|---|---|---|---|
| 2 mg | 10 U 0.1 mL · 2,000 mcg/mL | 20 U 0.2 mL · 1,000 mcg/mL | 30 U 0.3 mL · 667 mcg/mL | 10 |
| 5 mg | 4 U 0.04 mL · 5,000 mcg/mL | 8 U 0.08 mL · 2,500 mcg/mL | 12 U 0.12 mL · 1,667 mcg/mL | 25 |
| 10 mg | 2 U 0.02 mL · 10,000 mcg/mL | 4 U 0.04 mL · 5,000 mcg/mL | 6 U 0.06 mL · 3,333 mcg/mL | 50 |
1 mL = 100 units on a U-100 syringe. Water volume changes the units per dose, never the number of doses in the vial.
Measuring Ipamorelin: the math that matters
Ipamorelin is quoted in micrograms and sold in milligram vials, so every calculation starts with multiplying the vial by 1,000. With a 5 mg vial and 2 mL of bacteriostatic water the solution is 2,500 mcg/mL, so 200 mcg is 0.08 mL, or 8 units on a U-100 insulin syringe. From a 2 mg vial with 2 mL it is 20 units; from a 10 mg vial with 2 mL it is 4.
Vial size decides how readable the draw is. The 2 mg vial is the forgiving one: at 1,000 mcg/mL each unit is 10 mcg, so 100, 200 and 300 mcg are 10, 20 and 30 units. A 10 mg vial is the opposite, with 200 mcg at 2 units if you add only 1 mL. With the larger vials, use more water or a smaller-barrel syringe with finer markings.
Community protocols describe ipamorelin taken one to three times a day, and that frequency changes how long a vial lasts far more than the water does. A 5 mg vial holds 25 portions of 200 mcg: about 25 days at once daily, about 12 at twice daily and about 8 at three times daily. A 2 mg vial at three times daily lasts just over three days. Count this before mixing, because the mixed vial is then stored and punctured many times.
The only substantial human dosing data for ipamorelin come from a postoperative trial that used 0.03 mg/kg by IV infusion. That is a weight-based hospital regimen by a different route, not a figure to plug into a SubQ calculator. For a 70 kg adult it would be 2.1 mg, roughly ten times the community amount, which shows how far apart the two contexts are.
Common Ipamorelin measuring mistakes
- Using a 10 mg vial with 1 mL of water and trying to measure 2 units.
- Planning around doses per vial without accounting for two or three draws a day.
- Converting the IV trial's mg/kg figure into a SubQ dose.
- Adding ipamorelin and CJC-1295 units together in one syringe after only recalculating one of them.
- Entering 200 with the unit set to mg.
