Human dosing
Thymalin's dosing instructions in the schedule below describe a course-based administration pattern, not a single dose or an ongoing daily one.
| Period / condition | Dose | Escalation |
|---|---|---|
| Typical course | 10 mg IM once daily, 5–10 days | Starting schedule |
| Dose range | 5–20 mg per day (30–100 mg per course) | Increase if needed |
| Course repeat | Same course | Every 6–12 months |
Practical dosing and effect details
Thymalin, a complex of low-molecular-weight peptides isolated from the thymus, is used not as a daily medication but as a bounded course: 10 mg intramuscularly once daily for 5–10 days, totaling 30–100 mg per course.
The arithmetic lines up with the table: 5 days at 10 mg gives 50 mg, 10 days at 10 mg gives 100 mg, both fall inside the stated 30–100 mg course range, and a lower daily dose closer to 5 mg is what a longer course within the same total range implies.
This course-based dosing, rather than continuous administration, is typical of Soviet- and post-Soviet-era thymic peptide preparations: a short, intensive course lets a defined set of parameters be assessed before deciding whether to repeat it. The 6–12 month interval between courses shown in the table reflects that same course-based approach. This is a generalized reference to protocols described in the literature, not a medical recommendation and not instructions for self-administration without specialist guidance.
How to reconstitute
An example reconstitution for convenient dosing. The exact ratios depend on your vial. For research reference only — not medical guidance.
- 1Add the diluentUse bacteriostatic water. Example: 2 ml into a 10 mg vial.Thymalin10 mg+ 2 mlDiluent
- 2Get the concentrationExample: 10 mg in 2 ml =Thymalin5 mg/ml(5,000 mcg/ml)
- 3Work out the volume per doseFor example, for a 5 mg dose:5 mg = 1 ml= 100 u. (U-100)
This is only an example calculation. You can use a different diluent volume — plug your own numbers into the calculator. Open calculator →

Thymalin: reference regimens
Thymalin is a lyophilized thymic peptide reconstituted in 1–2 ml of isotonic saline before use and given by intramuscular injection (not intravenously).

Notes and safety
- • Thymalin is a research peptide. Human safety and efficacy data are limited.
- • The regimens shown are based on publications and research protocols, not clinical recommendations.
- • Individual reactions may vary. Published protocols typically start dosing at the lower end of the reported range.
- • Not recommended for use with chronic illness, pregnancy, or breastfeeding.
