Known For

Thymic peptide extract. Restores immune function, particularly in aging individuals. Regulates T-cell maturation and function. Less studied than Thymosin Alpha-1 but with decades of clinical use in Russia.

Mechanism of Action

Extract of bovine thymus — mixture of thymic peptides. Similar intent to Thymosin Alpha-1 but less purified/standardized. 30+ years Russian clinical use.

Body vs. External Supply

🟡 Natural/Topping Up

Brand / Trade Names

Thymalin® (available in Russia) Manufacturer: Various Russian pharmaceutical companies Not available outside Russia/CIS

Typical Research Dosage

5-10mg daily IM or SubQ for 5-10 day courses. Repeated 1-2x per year.

Vial Duration Guide

10mg vial at 10mg/day = 1 day per vial (short course, bulk vials needed).

Recommended Vial Size

★ 10mg (only size) At 10mg/day for 5-10 day courses = 1 vial per day. Used immediately. No shelf life issue.

Time to Effects

EARLY: During course FULL: 1-3 months post-course 5-10 day course: Immune modulation initiated. 1-3 months after course: Full immunomodulatory effects realised. The short course is designed to 'reset' thymic function. Benefits are measured in immune markers and illness frequency over the following months, not in immediate subjective feelings. Repeat courses 1-2x per year.

Contraindications & Do Not Combine

• Same immunosuppressant caution as Thymosin Alpha-1

Common Side Effects

Injection site reaction, allergic reaction possible (bovine-derived), flu-like symptoms. Limited Western safety data.

Drug Interactions

Immunosuppressives (may counteract)

Reversibility

Reversible

Storage Requirements

Lyophilized: room temp. Reconstituted: 2-8°C, 7-14 days.

State	Condition	Duration
Lyophilised (sealed)	room temp	12-24 months
Reconstituted	2-8C	1–2 weeks

Reconstitution Note

Reconstitute with bacteriostatic water (BAC water). Do not shake vigorously -- swirl gently to dissolve. Inject BAC water slowly down the side of the vial to avoid denaturing the peptide.
