What is Thymalin?
Thymalin (Timalina) is a polypeptide fraction extracted from the thymus gland, part of the Khavinson peptide bioregulator tradition. It is studied for immune modulation and sits in the bioregulator cluster alongside Epithalon. It is distinct from Thymosin Alpha-1, which vendors often conflate with it.
Reconstitution
Thymalin reconstitutes with bacteriostatic water. Draw 2mL down the inside wall of the vial, swirl gently until fully dissolved, and refrigerate. Do not shake.

Reconstitution Guide
Materials Needed
- Thymalin 20mg lyophilized vial
- Bacteriostatic water (BAC water)
- Insulin syringes (U-100, 29-31 gauge)
- Alcohol swabs
- Sharps container
Step-by-Step Instructions
- Prepare workspace — Clean environment, gather materials, thorough handwashing.
- Clean vial stoppers — Wipe both vials with alcohol swabs. Allow complete drying.
- Draw BAC water — Draw 2mL bacteriostatic water using a sterile syringe.
- Add to peptide — Inject slowly down the inside wall of the vial. Do not spray directly onto the powder.
- Dissolve — Allow a few minutes for complete dissolution. Gentle swirl only — no shaking.
- Verify — Solution should be clear.
- Label and store — Note reconstitution date. Refrigerate immediately.
Dosage Protocol
Concentration Calculations
With 20mg peptide in 2mL BAC water:
- Concentration: 10mg/mL (10000mcg/mL)
- Per unit (U-100 syringe): 100mcg per unit

Common Dose Calculations
| Desired Dose | Draw Volume | Syringe Units |
|---|---|---|
| 5mg | 0.50mL | 50 units |
| 10mg | 1.00mL | 100 units |
Research Considerations
Mechanism
As a thymic peptide complex, Thymalin is proposed to help normalise T-lymphocyte populations and immune balance, the classic Khavinson bioregulation rationale.
Sourcing for Research
Source from verified suppliers that provide third-party testing and certificates of analysis (COA) for each batch. Compare purity documentation, shipping conditions, and batch traceability before purchasing research materials.
Storage Requirements
Lyophilized (Powder)
- Temperature: -20°C or colder
- Duration: 2+ years
- Conditions: Dry, dark, protected from moisture
Reconstituted
- Temperature: 2-8°C (refrigerated)
- Duration: 2-3 weeks
- Conditions: Protected from light, never freeze
Safety Considerations
- Thymalin is a research compound
- Not approved for any indication in any jurisdiction
- Research use only — not for human consumption
- Use sterile technique; never reuse needles or syringes
