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.

Structure & identity

Sequence / structure
Polypeptide extract from calf thymus (bioregulator complex)

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

PhaseConditionGuidance
LyophilizedSealed 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.
ReconstitutedBacteriostatic water (0.9% benzyl alcohol), refrigeratedMost aqueous peptide solutions remain usable for approximately 2–4 weeks refrigerated; verify published stability data and label with reconstitution date.
Working aliquotsPre-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.

U-100 insulin syringe scale (100 units = 1 mL). Illustrative only — not dosing guidance.

Reconstitution steps

  1. Allow vial to reach room temperature (15–30 min)
  2. Swab rubber stopper with alcohol prep pad
  3. Draw calculated bacteriostatic water into syringe
  4. Inject diluent slowly down vial wall — do not spray directly onto cake
  5. Gently swirl until fully dissolved — do not shake vigorously
  6. Label with date, concentration, and diluent volume
  7. Refrigerate and use within your lab stability window

Often supplied in multi-vial kits; follow kit reconstitution instructions.
