Thymosin Alpha-1 Reconstitution & Dosage Calculator
This free Thymosin Alpha-1 calculator turns your vial size, the bacteriostatic water you add, and your target amount into a concentration, a draw volume, and the exact units on a U-100 insulin syringe. Thymosin Alpha-1 is one of the few compounds on this site with an approved product behind it — thymalfasin is licensed in around thirty countries — so its amounts sit at a well-defined scale.

Quick summary
- Converts vial size (mg), bacteriostatic water (mL), and a milligram amount into concentration, draw volume, and U-100 units.
- Reference math for the 10 mg vial, at the low-milligram scale the approved product uses.
- Educational research and measurement tool only — it does not diagnose, treat, or recommend an amount.
What this Thymosin Alpha-1 calculator does
This calculator does one job well: it turns your vial size, the amount of bacteriostatic water you add, and your target amount into a concentration (mg/mL), a draw volume (mL), and the matching units on a U-100 insulin syringe. Change any input and the result updates instantly.
Thymosin Alpha-1 ships as a freeze-dried powder. Before it can be measured into a syringe it has to be reconstituted — dissolved in bacteriostatic water. How much water you add sets the concentration, and the concentration sets how many units each amount works out to. The presets above cover the most common Thymosin Alpha-1 vial setups; use the custom fields for anything else.
How to use the Thymosin Alpha-1 calculator
Pick your syringe
Choose the U-100 insulin syringe you'll draw with. Smaller syringes (0.3 mL / 30u) have finer lines, which helps when the draw is small.
Enter your vial and water
Set the milligrams in your Thymosin Alpha-1 vial and the bacteriostatic water you added. Together these set the concentration.
Set your target amount
Toggle mg or mcg and pick (or type) the amount you're measuring for. The calculator does the conversion for you.
Read the draw
The result panel shows concentration, draw volume, and the exact U-100 units to pull, plus how many doses your vial contains.
Thymosin Alpha-1 reconstitution math, explained
The math is short. Concentration = vial size ÷ bacteriostatic water. Draw volume = target amount ÷ concentration. Units = draw volume × 100 (a U-100 syringe reads 100 units per mL). The table below shows common Thymosin Alpha-1 setups and the units for a 1 mg amount at each.
| Vial size | Bac water | Concentration | Units per 1 mg |
|---|---|---|---|
| 10 mg | 1.0 mL | 10 mg/mL | 10 units |
| 10 mg | 2.0 mL | 5 mg/mL | 20 units |
| 10 mg | 2.5 mL | 4 mg/mL | 25 units |
| 10 mg | 5.0 mL | 2 mg/mL | 50 units |
| 5 mg | 2.0 mL | 2.5 mg/mL | 40 units |
Thymosin Alpha-1 amount-to-units reference
How common amounts convert to U-100 syringe units at two example concentrations. These are arithmetic conversions for reference, not a recommendation of any amount.
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 0.8 mg (800 mcg) | 0.16 mL | 16 units |
| 1.6 mg (1600 mcg) | 0.32 mL | 32 units |
| 3.2 mg (3200 mcg) | 0.64 mL | 64 units |
| Amount | Volume (mL) | U-100 units |
|---|---|---|
| 0.8 mg (800 mcg) | 0.4 mL | 40 units |
| 1.6 mg (1600 mcg) | 0.8 mL | 80 units |
| 3.2 mg (3200 mcg) | 1.6 mL | 160 units |
Mixing, color & storage tips
A well-defined scale
Unlike most compounds here, Thymosin Alpha-1 has an approved product with a labelled amount, so the range is not guesswork. At 5 mg/mL a 1.6 mg target is 32 units — comfortably readable on a U-100 syringe.
Mixing without foam
Add the bacteriostatic water slowly against the inside wall and swirl gently until clear. Do not shake.
Storage
Keep the dry powder cold and dark. Refrigerate once reconstituted, protect from light, and plan around a limited window. Do not freeze a mixed vial.
Not the same as Thymalin
Thymosin Alpha-1 is a single defined 28-amino-acid peptide with a regulatory dossier. Thymalin is an undefined calf-thymus extract from a different research tradition. They are frequently conflated and should not be.

Thymosin Alpha-1 — frequently asked questions
What does this Thymosin Alpha-1 calculator tell me?
It converts your vial size, bacteriostatic water volume, and target amount into concentration in mg/mL, draw volume in mL, and U-100 syringe units. It is a measurement tool, not a recommendation.
Is the Thymosin Alpha-1 calculator free?
Yes — free, browser-based, and no account is required.
How much bacteriostatic water do I add to a 10 mg vial?
A 10 mg vial with 2 mL makes 5 mg/mL, so a 1.6 mg target is 32 units. Using 5 mL makes 2 mg/mL and the same amount becomes 80 units.
How many units is 1.6 mg of Thymosin Alpha-1?
At 5 mg/mL it is 32 units (0.32 mL). At 2 mg/mL it is 80 units (0.8 mL). Units always depend on your exact concentration.
Is Thymosin Alpha-1 FDA-approved?
Not in the United States. It is approved as thymalfasin in around thirty other countries, principally for chronic hepatitis B. Research-grade material is not that product and is supplied research-use-only.
Is this medical advice?
No. This page and calculator are for education and research planning only. Products referenced are sold strictly as research chemicals and are not for human or veterinary use.
