How much bacteriostatic water for a 10 mg Thymosin Alpha-1 vial?

The amount of water does not change how much Thymosin Alpha-1 is in the vial; it sets the concentration. With 1 mL a 10 mg vial is 10 mg/mL, with 2 mL it is 5 mg/mL and with 3 mL it is 3.333 mg/mL. More water makes each unit weaker, so a given amount takes more units to draw.

How many mcg are in one unit of a 10 mg Thymosin Alpha-1 vial?

With 2 mL of water, one unit on a U-100 syringe holds 50 mcg (5,000 mcg per mL divided by 100). The table above gives the figure for other vial sizes and volumes.

Thymosin Alpha-1 dosage calculator

Pick a Thymosin Alpha-1 vial size, enter the bacteriostatic water added and, if you want, an amount per draw. The calculator gives the concentration and how many units that is on a U-100 insulin syringe. It does arithmetic only and does not suggest an amount.

U-100 syringes · 100 units = 1 mL · 1 mg = 1,000 mcg

Worked example

A 10 mg Thymosin Alpha-1 vial with 2 mL of bacteriostatic water is 5 mg/mL (5,000 mcg/mL). One unit on a U-100 syringe is 0.01 mL, so each unit holds 50 mcg. To find how many units an amount is, divide the amount in mcg by 50.
