Frequently Asked
How do I reconstitute Follistatin 344?
Add 1 mL of bacteriostatic water to a 1 mg vial, injecting slowly down the inside wall. Swirl gently; never shake. This yields a concentration of 1000 µg/mL.
What is the recommended dose of Follistatin 344?
A typical research dose is 100 µg. Consult the ASCEND calculator for your specific vial concentration and draw volume.
How many doses are in a Follistatin 344 vial?
A 1 mg vial reconstituted with 1 mL BAC water yields approximately 10 doses at 100 µg each.
How many IU is 100 µg of Follistatin 344 on a syringe?
With a 1 mg vial reconstituted in 1 mL bacteriostatic water, the concentration is 1000 µg/mL. For a 100 µg dose: Volume = 100 µg ÷ 1000 µg/mL = 0.1 mL. Draw to the 10 line on a 100-unit insulin syringe. You can adjust these values in the ASCEND calculator for any vial size.
What does a Follistatin 344 dosage calculator do?
A Follistatin 344 dosage calculator converts your vial size and BAC water volume into an exact syringe draw in IU. Enter your vial strength (1 mg), reconstitution volume (1 mL), and target dose to get the precise line to draw on an insulin syringe.
What is the Follistatin 344 reconstitution calculator formula?
Draw volume (mL) = Dose (µg) divided by Concentration (µg/mL). For a 1 mg vial with 1 mL BAC water: concentration = 1000 µg/mL. For a 100 µg dose, the ASCEND calculator gives the exact IU line on your syringe instantly.
