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 mg20 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? →

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.
