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).
Frequently asked questions
How many IU are in 1 mg of HGH?+
A common approximation is about 3 IU per mg, so 1 mg ≈ 3 IU. Potency varies by product, so confirm the conversion stated on your vial or by your pharmacy.
How much BAC water should I use for an HGH vial?+
1–2 mL per vial is common. Less water gives a smaller, more concentrated draw; more water makes small IU doses easier to measure on an insulin syringe.
What syringe is used for HGH?+
A U-100 insulin syringe is standard. Because HGH doses are small, reading the dose in units on a U-100 syringe is usually the most accurate approach.
