Testagen Dosing & Reconstitution Calculator

Add 3 mL of bacteriostatic water to a 20 mg vial, injecting slowly down the inside wall. Swirl gently; never shake. This yields a concentration of 6666.7 µg/mL.

A typical research dose is 100 µg. Consult the ASCEND calculator for your specific vial concentration and draw volume.

A 20 mg vial reconstituted with 3 mL BAC water yields approximately 200 doses at 100 µg each.

With a 20 mg vial reconstituted in 3 mL bacteriostatic water, the concentration is 6666.7 µg/mL. For a 100 µg dose: Volume = 100 µg ÷ 6666.7 µg/mL = 0.015 mL. Draw to the 1.5 line on a 100-unit insulin syringe. You can adjust these values in the ASCEND calculator for any vial size.

A Testagen dosage calculator converts your vial size and BAC water volume into an exact syringe draw in IU. Enter your vial strength (20 mg), reconstitution volume (3 mL), and target dose to get the precise line to draw on an insulin syringe.

Draw volume (mL) = Dose (µg) divided by Concentration (µg/mL). For a 20 mg vial with 3 mL BAC water: concentration = 6666.7 µg/mL. For a 100 µg dose, the ASCEND calculator gives the exact IU line on your syringe instantly.
