How to Reconstitute Follistatin-344
Updated today
Follistatin-344 is supplied as a 1 mg lyophilized (freeze-dried) vial and must be reconstituted with bacteriostatic water before use. Adding 2 mL to a 1 mg vial yields a concentration of 0.5 mg/mL — so a 250 mcg reference dose is 50 units on a standard U-100 insulin syringe. Use more water for a more dilute, easier-to-measure solution, or less for a more concentrated one; the amount of compound in the vial is the same either way. Adjust the calculator below to match your exact vial size and target dose.
| Dose | Units (U-100) | Volume |
|---|---|---|
| 100 mcg | 20 units | 0.2 mL |
| 250 mcg | 50 units | 0.5 mL |
| 500 mcg | 100 units | 1 mL |
| 1000 mcg | 200 units | 2 mL |
