Thymosin Alpha-1 reconstitution calculator
Thymosin Alpha-1 ships as a 5 mg vial of lyophilized powder. Pick the size, type the water volume, read the concentration. The molecular weight is already filled in, so the molar result is there too.
- Concentration
- 2.5 mg/mL
- 2.5 µg/µL · 2500 µg/mL

Concentration = peptide mass ÷ diluent volume. Molarity = (mg/mL ÷ g/mol) × 1000. Research use only.

What the numbers mean for Thymosin Alpha-1
Thymosin Alpha-1 has a molecular weight of 3108.3 g/mol (C129H215N33O55). So 5 mg is about 1.61 micromoles, whatever volume you dissolve it in. At 2.5 mg/mL that is 0.804 mM.
The vial holds 5 mg of powder and no diluent. Add bacteriostatic water down the inside of the glass, swirl, and do not shake. The reconstitution guide covers the handling; this page covers the arithmetic.
Common questions
How much water do I add to a 5 mg vial of Thymosin Alpha-1?+
Any volume that gives a concentration you can measure easily. 1 mL gives 5 mg/mL, 2 mL gives 2.5 mg/mL, 5 mL gives 1 mg/mL. The peptide amount stays 5 mg whatever you add.
What is the concentration of Thymosin Alpha-1 5 mg in 2 mL?+
2.5 mg/mL, which is the same as 2.5 µg/µL. With a molecular weight of 3108.3 g/mol that is 0.804 mM.
Where does the Thymosin Alpha-1 molecular weight come from?+
The reference value on the product's Specifications tab, 3108.3 g/mol. The observed mass for the vial you receive is on its own lab report, which the QR code on the vial opens.
