How many units of Thymalin should I draw?

It depends on your vial size, BAC water, and dose. For a 10mg vial with 2mL BAC water, a beginner dose of 5000mcg is typically 100 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to Thymalin?

The standard amount is 2mL of bacteriostatic water for a 10mg vial. More water gives a more dilute solution — easier to measure small doses. Less water means fewer injections per vial. Adjust the BAC water slider in the calculator to see how it changes your syringe units.

How long does a Thymalin vial last?

At a beginner dose of 5000mcg daily, a 10mg vial lasts about 2 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for Thymalin?

Most people use a U-100 insulin syringe (1mL / 100 units). For very small doses, a U-50 or U-30 syringe gives better precision. The calculator adjusts units automatically for whichever syringe you pick.

Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

Thymalin Dosing Protocol

Level	Dose / Injection	Frequency
Beginner	5mg	Daily
Moderate	10mg	Daily
Aggressive	20mg	Daily

Note: Thymic peptide bioregulator developed by Khavinson. Standard protocol is 5-10mg daily for 5-10 days, repeated every 6 months. Contains active dipeptides EW (Glu-Trp) and KE. Extracted from calf thymus.

About Thymalin

Thymalin is a natural peptide complex isolated from calf thymus gland, developed by Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. It contains several bioactive short peptides — most notably the dipeptide L-Glu-L-Trp (EW), which was later synthesized as the drug Thymogen. Thymalin activates T-cell differentiation, restores CD4/CD8 ratios, enhances natural killer cell activity, and modulates cytokine production. It has been used in Russian and Eastern European clinical practice for over 40 years as an immunocorrector, particularly in elderly patients with age-related immune decline.
