Overview
Thymosin alpha-1 is a naturally occurring immune-signaling peptide produced by the thymus. It is approved in several countries as an adjunct for certain infections and as an immune modulator, and it has been studied broadly for balancing immune responses.
How it’s thought to work
- Enhances T-cell maturation and function.
- Modulates innate immunity and inflammatory signaling toward balance.
Researched uses
- Immune support
- Adjunct in certain viral infections (approved use in some regions)
- Recovery research
Commonly cited protocol
| Typical dose | ~1.6 mg |
|---|---|
| Frequency | A couple times weekly |
| Route | Subcutaneous injection |
| Notes | Clinical protocols vary by indication. |
Reconstitution
Often a 5 mg or 10 mg vial. A 5 mg vial with 2 mL water = 2.5 mg/mL, so 1.6 mg = 64 units on a U-100 syringe.
Thymosin Alpha-1 dosage calculator
The calculator below is pre-filled with Thymosin Alpha-1’s commonly cited vial size and dose. Adjust the vial amount, bacteriostatic water, or dose to match your own vial — it will show the exact insulin-syringe units to draw, the concentration, and how many doses the vial holds.
Add 2 mL of bacteriostatic water to your 5 mg vial. That gives you about 3 doses of 1.6 mg. For each dose, draw 64 units into a 100-unit insulin syringe.

Cautions
- Approved in some countries; research/off-label elsewhere.
- Injection-site reactions possible.
- Consult a clinician if immunocompromised or on immune therapy.
