Thymosin Alpha-1: 5 mg vial with 2 mL water
Quick answer
Adding 2 mL of bacteriostatic water to a 5 mg Thymosin Alpha-1 vial gives 2.5 mg/mL (2500 mcg/mL), so each unit on a U-100 insulin syringe holds 25 mcg. A 300 mcg dose is 12 units (0.12 mL), and the vial holds about 16 doses of that size.
Concentration
- Vial: 5 mg Thymosin Alpha-1
- Bacteriostatic water: 2 mL
- Concentration: 2.5 mg/mL (2500 mcg/mL)
- 1 unit on a U-100 syringe = 25 mcg
Thymosin Alpha-1 dose to syringe units
| Dose | Syringe units (U-100) | Volume | Doses per vial |
|---|---|---|---|
| 50 mcg | 2 units | 0.02 mL | 100 |
| 100 mcg | 4 units | 0.04 mL | 50 |
| 200 mcg | 8 units | 0.08 mL | 25 |
| 250 mcg | 10 units | 0.1 mL | 20 |
| 300 mcg (protocol dose) | 12 units | 0.12 mL | 16 |
| 500 mcg (protocol dose) | 20 units | 0.2 mL | 10 |
| 750 mcg | 30 units | 0.3 mL | 6 |
| 1 mg | 40 units | 0.4 mL | 5 |

Common questions
How many units is 300 mcg of Thymosin Alpha-1 from a 5 mg vial with 2 mL water?
300 mcg is 12 units (0.12 mL) on a U-100 insulin syringe. With 2 mL of water in a 5 mg vial, each unit holds 25 mcg. For comparison: 200 mcg = 8 units, 250 mcg = 10 units, 500 mcg = 20 units.
What is the concentration of a 5 mg Thymosin Alpha-1 vial mixed with 2 mL of water?
5 mg divided by 2 mL is 2.5 mg/mL, or 2500 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 25 mcg per unit.
How many 300 mcg doses are in a 5 mg vial?
About 16. The water volume changes how many units each dose takes, not how many doses the vial holds.
How much water should I add to a 5 mg Thymosin Alpha-1 vial?
The Crestigen Thymosin Alpha-1 protocol uses 3 mL. 2 mL works too as long as you calculate units for this concentration (2.5 mg/mL) and label the vial.
