Thymalin Dosing Calculator
Thymalin: Thymic peptide bioregulator for immune restoration.
Pre-filled with the most-reported community reconstitution protocol for Thymalin. See how 1 mL and 2 mL of bacteriostatic water change concentration and syringe-draw volume, then adjust the calculator below for your own vial.
Quick answer · Community-reported standard
A 10 mg vial of Thymalin reconstituted with 2 mL of bacteriostatic water yields a concentration of 5.00 mg/mL. At that concentration, a 5 mg dose of Thymalin equals 100 units on a U-100 insulin syringe (1.000 mL). Thymalin is typically administered once daily via intramuscular.
Thymalin reconstitution: 1 mL vs 2 mL bac water
Bacteriostatic water volume is flexible. Less water means higher concentration and smaller injection volumes; more water means lower concentration and easier dose precision. Both options below are valid for a 10 mg vial.
| BAC water added | Concentration | Volume per 5 mg dose | Draw on U-100 syringe (units) |
|---|---|---|---|
| 1 mL | 10.00 mg/mL | 0.500 mL | 50 units |
| 2 mL | 5.00 mg/mL | 1.000 mL | 100 units |

Adjunctive immunotherapy during chemotherapy
Clinical- Dose
- 5-10 mg daily via intramuscular injection
- Frequency
- Once daily
- Duration
- 5-7 day course during or between chemotherapy cycles
Used in Russian oncology practice to support immune recovery; timing relative to chemotherapy cycles is critical
Thymalin reconstitution & storage
Thymalin is supplied as a lyophilized powder in sealed vials, typically containing 10 mg per vial. Reconstitute with 1-2 mL of sterile 0.9% sodium chloride solution (normal saline) or sterile water for injection. Gently swirl the vial to dissolve; do not shake vigorously. Use immediately after reconstitution. The reconstituted solution should be clear and free of particulate matter.
Store lyophilized thymalin at 2-8 degrees Celsius (refrigerated) protected from light. Do not freeze. Shelf life is typically 2-3 years for the lyophilized product when stored properly. Reconstituted solution should be used immediately; do not store reconstituted thymalin.
Thymalin dosing FAQ
How much bacteriostatic water should I add to a 10 mg vial of Thymalin?
The community standard is 2 mL of bacteriostatic water for a 10 mg Thymalin vial. That gives a concentration of 5.00 mg/mL, so a 5 mg dose is 100 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 10.00 mg/mL and halves the draw to 50 units. Less water = smaller injection volume but harder to measure precisely.
How many syringe units is a 5 mg dose of Thymalin?
On a standard U-100 insulin syringe, a 5 mg dose of Thymalin is 100 units when the 10 mg vial is reconstituted with 2 mL of bacteriostatic water (5.00 mg/mL). If you use 1 mL of bac water instead, draw 50 units (10.00 mg/mL).
What is the standard Thymalin dose?
Community-reported protocols for Thymalin typically use 5 mgâ10 mg once daily via Intramuscular. 5 mg is a common starting dose. Follows the Khavinson bioregulator cycling paradigm; IM or SubQ injection, short intensive courses with months between cycles
How long does a vial of Thymalin last at 5 mg once daily?
A 10 mg vial of Thymalin contains roughly 2 doses at 5 mg per injection. At once daily dosing, that is approximately 2 days (about 0 weeks) of supply per vial. Reconstituted Thymalin should generally be used within 28 days when refrigerated.
Where do you inject Thymalin?
Thymalin is typically injected intramuscular. Common sites reported in the literature and by users include: Gluteal muscle (dorsogluteal), Deltoid muscle, Vastus lateralis (lateral thigh). Rotate sites with each injection to reduce localized irritation.
Can I use sterile water instead of bacteriostatic water for Thymalin?
Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like Thymalin because it inhibits microbial growth and lets a single vial be used over multiple weeks. Sterile water has no preservative and should generally be reserved for single-use preparations only.
