Frequently Asked
How do I reconstitute Thymalin?
Add 2 mL of bacteriostatic water to a 10 mg vial, injecting slowly down the inside wall. Swirl gently; never shake. This yields a concentration of 5 mg/mL.
What is the recommended dose of Thymalin?
A typical research dose is 5 mg. Consult the ASCEND calculator for your specific vial concentration and draw volume.
How many doses are in a Thymalin vial?
A 10 mg vial reconstituted with 2 mL BAC water yields approximately 2 doses at 5 mg each.
Peptide Intelligence
What is Thymalin and how does it differ from Thymosin Alpha-1?
Thymalin is a natural extract of bovine thymic tissue containing a mixture of thymic peptides, while Thymosin Alpha-1 is a purified synthetic single peptide. Thymalin provides broader thymic factors and is used in similar immune-restoration contexts in the Russian bioregulator research tradition.
What is the typical Thymalin research protocol?
Thymalin is used at 5–10 mg per dose via subcutaneous or intramuscular injection for 5–10 consecutive days per course, 1–2 courses per year. It was one of the original bioregulator peptides studied in Russian clinical trials showing immune restoration and life extension.
What immune outcomes does Thymalin research show?
Clinical research from St. Petersburg shows Thymalin normalizes T-cell counts and function in elderly subjects, improves NK cell activity, and reduces infection susceptibility. Long-term follow-up studies (10–12 years) suggested reduced mortality compared to controls.
