Use this thymosin alpha-1 calculator to convert vial strength and BAC water volume into a precise draw. Thymosin alpha-1 is an immune-modulating peptide; this page covers the reconstitution math only.
- Common vial examples
- 5 / 10 mg
- Example dose
- 1.6 mg
- Common syringe
- U-100 insulin
- Last reviewed
Storage before and after reconstitution: Lyophilised 2–8°C; reconstituted vial refrigerated and protected from light.
Quick answers: Thymosin Alpha-1 doses in units
With a 5 mg vial mixed with 2 mL of bacteriostatic water (2.5 mg/mL), on a U-100 insulin syringe:
- How many units is 0.8 mg of Thymosin Alpha-1?
- 32 units (0.32 mL)
- How many units is 1.6 mg of Thymosin Alpha-1?
- 64 units (0.64 mL)
Educational maths only, not a dose recommendation. Use the calculator above for your own vial, water volume and syringe.
Quick math example
A 5 mg vial mixed with 2 mL gives 2,500 mcg/mL. A 1.6 mg dose is 0.64 mL, which equals 64 units on a U-100 syringe.
Thymosin Alpha-1 reconstitution reference
U-100 units to draw for each common Thymosin Alpha-1 dose, by vial size, reconstituted with 2 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.
| Vial | Concentration | 800 mcg | 1.6 mg |
|---|---|---|---|
| 5 mg | 2.5 mg/mL | 32 u(0.32 mL) | 64 u(0.64 mL) |
| 10 mg | 5 mg/mL | 16 u(0.16 mL) | 32 u(0.32 mL) |

Educational reference only — not a dose recommendation. Units assume a U-100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.
How the thymosin alpha-1 calculation works
Thymosin alpha-1 is labelled in milligrams and dosed in milligrams or micrograms. The calculator converts the vial total to mcg, divides by water volume for concentration, then divides your target by that concentration.
- 5 mg vial = 5,000 mcg total
- 5,000 mcg / 2 mL = 2,500 mcg per mL
- 1,600 mcg target = 0.64 mL draw
Thymosin alpha-1 5 mg vial with 2 mL example
A 5 mg thymosin alpha-1 vial mixed with 2 mL gives 2.5 mg/mL, or 2,500 mcg/mL.
A 1.6 mg (1,600 mcg) dose is 0.64 mL, which equals 64 units on a U-100 syringe. An 0.8 mg dose halves to 0.32 mL, or 32 units.
- 5 mg / 2 mL = 2.5 mg/mL
- 1,600 mcg / 2,500 mcg per mL = 0.64 mL = 64 units
- 800 mcg / 2,500 mcg per mL = 0.32 mL = 32 units
Reconstitution and storage
Use the diluent your protocol or pharmacy specifies. Once reconstituted, keep the vial refrigerated and protected from light, and confirm a beyond-use date. The calculator returns the draw for whatever vial and water amounts you enter.
- Refrigerate the reconstituted vial; protect from light
- Confirm a beyond-use date with your source
- Re-run the math when vial size, water, or dose changes
