HGH is measured in IU
Most HGH vials are labelled in international units (IU), not milligrams. A common approximation is about 3 IU per 1 mg, but check your product — potency varies.
To use this calculator, convert the vial's IU to mg first, then enter that mg amount and your BAC water volume.
- 10 IU vial ≈ 3.33 mg
- Reconstitute with 1 mL → 3.33 mg/mL
- A 2 IU (~0.67 mg) dose ≈ 0.2 mL = 20 units on a U-100 syringe
Worked HGH example
A 10 IU vial reconstituted with 1 mL gives roughly 3.33 mg/mL. A 2 IU dose is about 0.67 mg, which is 0.2 mL — 20 units on a U-100 insulin syringe.
Using 2 mL of BAC water instead halves the concentration, so the same 2 IU dose becomes 0.4 mL (40 units).
Worked example with a 15 IU vial
A 15 IU vial is about 5 mg of HGH. Reconstituted with 1.5 mL, that is roughly 3.33 mg/mL — the same concentration as the 10 IU in 1 mL example, because the IU-to-water ratio matches.
At that concentration a 2 IU (~0.67 mg) dose is still 0.2 mL, or 20 units. Keeping the IU-per-mL ratio consistent across vial sizes keeps your unit count familiar.
- 15 IU ≈ 5 mg
- 5 mg / 1.5 mL ≈ 3.33 mg/mL
- 2 IU dose ≈ 0.2 mL = 20 U-100 units
Choose BAC water to make IU doses easy to read
Because HGH doses are small, the water volume you pick decides how many syringe units a dose lands on. More water spreads a dose across more units, which can make a 1 IU or 2 IU dose easier to measure precisely.
For a 10 IU vial: 1 mL puts a 2 IU dose at 20 units, while 2 mL puts the same dose at 40 units. Pick whichever lands your usual dose on a clear, easy-to-read mark.
- More BAC water = more units per IU = easier small-dose reading
- 10 IU in 1 mL: 2 IU dose = 20 units
- 10 IU in 2 mL: 2 IU dose = 40 units
