Overview
Thymalin is a polypeptide complex from the thymus gland studied for immune restoration in aging and post-stress models. Often co-researched with thymosin alpha-1 and epitalon in Khavinson bioregulator protocols. Calf thymus polypeptide extract normalizing immune markers in aging rodent models.

Mechanism
Polypeptide thymic extract normalizes T-cell ratios and immune markers in aging models. T-cell ratio normalization and thymic involution reversal are recurring immune-aging endpoints.

Stability & storage phases
| Phase | Condition | Guidance |
|---|---|---|
| Lyophilized | Sealed vial, refrigerated (2–8 °C) | Intact lyophilized cake or powder is typically stable for months to years per published stability data; protect from moisture, light, and repeated freeze-thaw of the dry vial. |
| Reconstituted | Bacteriostatic water (0.9% benzyl alcohol), refrigerated | Most aqueous peptide solutions remain usable for approximately 2–4 weeks refrigerated; verify published stability data and label with reconstitution date. |
| Working aliquots | Pre-drawn syringes or microtubes, frozen (−20 °C) | Aliquot promptly after mixing to limit freeze-thaw cycles on the main vial; thaw once and use to reduce protease-mediated degradation. |
Stability windows are formulation-dependent — verify published data and your lab SOP.
Reconstitution reference table
| Vial (mg) | Diluent (mL) | mcg/mL | Units @ 100 mcg | Units @ 250 mcg | Units @ 500 mcg |
|---|---|---|---|---|---|
| 10 | 2 | 5000.0 | 2 | 5 | 10 |
U-100 insulin syringe scale (100 units = 1 mL). Illustrative only — not dosing guidance.
Reconstitution steps
- Allow vial to reach room temperature (15–30 min)
- Swab rubber stopper with alcohol prep pad
- Draw calculated bacteriostatic water into syringe
- Inject diluent slowly down vial wall — do not spray directly onto cake
- Gently swirl until fully dissolved — do not shake vigorously
- Label with date, concentration, and diluent volume
- Refrigerate and use within your lab stability window
Often supplied in multi-vial kits; follow kit reconstitution instructions.
