Concentration2500mcg / mL

Doses Per Vial10approx. doses

Volume Per Dose0.200mL

Syringe Units20.0IU on U-100

Adding 2 mL of BAC water to a 5 mg vial gives 2500 mcg/mL. A 500 mcg dose requires 0.200 mL (20.0 units on a U-100 syringe) — approximately 10 doses per vial.

Always verify independently before laboratory application. For research use only — not for human or animal consumption.
