Thymalin Reconstitution Calculator & Dosage Chart
Also known as: Thymic peptide bioregulator, Thymus extract peptide
Quick answer: mix a 10 mg vial of Thymalin with 2 ml of bacteriostatic water. That gives 5.00 mg/ml, so a typical 10 mg dose is 200 units on a U-100 insulin syringe — about 1 doses per vial. Reported protocols range 5 mg–20 mg, daily for 5–10 days, cycled 1–2x per year.
Thymalin is a thymus-derived peptide bioregulator from the Russian Khavinson school, studied for immune restoration in aging and, in long-term Russian trials, for reduced mortality in elderly cohorts. Dosed in short annual courses rather than continuously. Full overview: what is Thymalin? →

Typical range: 5 mg–20 mg, daily for 5–10 days, cycled 1–2x per year
⚠ This dose needs more than one full 1 ml syringe (2.00 ml). Use less water when reconstituting, or split into multiple injections.
Thymalin mixing chart — 10 mg vial
Units to draw for a 10 mg dose at different water amounts. More water never changes the dose — only the volume you measure.
| Water added | Concentration | 10 mg dose = | Per unit |
|---|---|---|---|
| 1 ml | 10.00 mg/ml | 100 units | 100.0 mcg |
| 2 ml ← typical | 5.00 mg/ml | 200 units (>1 syringe) | 50.0 mcg |
| 2.5 ml | 4.00 mg/ml | 250 units (>1 syringe) | 40.0 mcg |
| 3 ml | 3.33 mg/ml | 300 units (>1 syringe) | 33.3 mcg |
| 5 ml | 2.00 mg/ml | 500 units (>1 syringe) | 20.0 mcg |
Thymalin reconstitution by vial size — 10 mg / 20 mg
How much water for each vial size, and what a 10 mg dose becomes in syringe units. Bigger vials hold more doses; they do not change the dose.
| Vial | Water | Concentration | 10 mg dose = | Doses per vial |
|---|---|---|---|---|
| 10 mg | 1 ml | 10.00 mg/ml | 100 units | 1 |
| 10 mg | 2 ml | 5.00 mg/ml | 200 units (>1 syringe) | 1 |
| 10 mg | 3 ml | 3.33 mg/ml | 300 units (>1 syringe) | 1 |
| 20 mg | 2 ml | 10.00 mg/ml | 100 units | 2 |
| 20 mg | 3 ml | 6.67 mg/ml | 150 units (>1 syringe) | 2 |
| 20 mg | 5 ml | 4.00 mg/ml | 250 units (>1 syringe) | 2 |
Protocol reference
FAQ
How much bacteriostatic water do you add to Thymalin?+
Most protocols mix a 10 mg vial of Thymalin with 2 ml of bacteriostatic water. This gives 5.00 mg/ml, so a typical 10 mg dose is 200 units on a U-100 insulin syringe. More or less water is fine — it only changes the volume you draw, not the dose.
What is a typical Thymalin dose?+
Commonly reported Thymalin protocols use 5 mg to 20 mg, daily for 5–10 days, cycled 1–2x per year, administered via subcutaneous injection. These are reference figures from published protocols, not medical advice — individual use should be guided by a healthcare provider.
How many doses are in a 10 mg vial of Thymalin?+
At 10 mg per dose, a 10 mg vial contains about 1 doses, regardless of how much water you add.
How should Thymalin be stored?+
Reconstituted: refrigerate, use within 2–4 weeks.
