Quick math example
A 5 mg vial mixed with 2.5 mL gives 2,000 mcg/mL. A 200 mcg dose is 0.1 mL, which equals 10 units on a U-100 syringe.
Reconstitution reference
U100 units to draw for each common Ipamorelin dose, by vial size, reconstituted with 2.5 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.
| Vial | Concentration | 100 mcg | 200 mcg | 300 mcg |
|---|---|---|---|---|
| 2 mg | 0.8 mg/mL | 12.5 u(0.13 mL) | 25 u(0.25 mL) | 37.5 u(0.38 mL) |
| 5 mg | 2 mg/mL | 5 u(0.05 mL) | 10 u(0.1 mL) | 15 u(0.15 mL) |
Educational reference only — not a dose recommendation. Units assume a U100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.
How the ipamorelin calculation works
Ipamorelin is commonly labelled in milligrams per vial while target amounts are often discussed in micrograms. The calculator converts the vial amount into mcg, divides by the water volume, and returns the draw volume for your target.
Small-volume draws are common with growth-hormone secretagogue protocols, so checking syringe units against mL helps avoid misreading the scale.
- 5 mg vial = 5,000 mcg total
- 5,000 mcg / 2.5 mL = 2,000 mcg per mL
- 200 mcg target = 0.1 mL draw
Ipamorelin 5 mg vial with 2.5 mL example
A 5 mg ipamorelin vial contains 5,000 mcg. Mixed with 2.5 mL, that gives 2,000 mcg/mL.
A 200 mcg dose is 0.1 mL at this concentration, which equals 10 units on a U-100 syringe. A 300 mcg dose would be 0.15 mL, or 15 units.
- 5 mg / 2.5 mL = 2,000 mcg/mL
- 200 mcg / 2,000 mcg per mL = 0.1 mL = 10 U-100 units
- 300 mcg / 2,000 mcg per mL = 0.15 mL = 15 U-100 units
Ipamorelin 2 mg vial with 1 mL example
A smaller 2 mg vial mixed with 1 mL gives 2,000 mcg/mL — the same concentration as the 5 mg in 2.5 mL example, because both keep the same mg-to-mL ratio.
Matching concentrations across vial sizes is handy: a 200 mcg dose stays at 0.1 mL (10 units) whichever of these two setups you use, so the syringe reading does not change.
- 2 mg / 1 mL = 2,000 mcg/mL
- Same ratio as 5 mg / 2.5 mL, so the same 10-unit draw
- A consistent concentration keeps your unit count stable
Single-compound vs blended vials
This page is for ipamorelin-only vial math. If your vial combines CJC-1295 and Ipamorelin, use the CJC-1295 / Ipamorelin calculator and confirm the labelled ratio before interpreting component-specific amounts.
