Thymosin Alpha 1
Tα1Immune-modulating thymic peptide.
Also known as: Tα1, Zadaxin
Overview
Thymosin Alpha 1 is a thymic peptide studied extensively in immune-modulation, T-cell function, and host-defense research.
A thymus-derived 28-amino-acid peptide and one of the most clinically validated immune modulators — approved in several countries (as thymalfasin) for hepatitis and as a vaccine adjuvant. Research centers on T-cell maturation and balanced immune-response enhancement.
Studied for promoting T-cell maturation and modulating innate and adaptive immune signaling via toll-like receptors.

How to reconstitute
Reconstitute with bacteriostatic water, swirl gently, and refrigerate. Avoid shaking to preserve the peptide.
- 1Allow the vial to reach room temperature (15–20 minutes).
- 2Swab the stopper with alcohol and let it air dry.
- 3Add bacteriostatic water slowly down the vial wall.
- 4Swirl gently until dissolved into a clear solution.
- 5Refrigerate at 2–8 °C and protect from light.
Quality indicators
Uniform white powder
Lyophilized cake should be white to off-white without discoloration.
Clear solution
Reconstitutes to a clear, colorless, particle-free solution.
Cold-chain integrity
Reconstituted solution requires 2–8 °C storage.
Slight clumping
Small clumps that dissolve completely with gentle swirling are acceptable — shipping can cause minor compaction.
Collapsed or melted appearance
Powder that looks collapsed, melted, or stuck to the vial walls may have been exposed to heat in transit.
Cloudy after reconstitution
Persistent cloudiness, particles, or precipitate after gentle mixing can indicate a degraded or contaminated peptide.
Reported observations & safety
Safety signals reported in the research literature. Compiled for scientific awareness — not medical advice.
- Among the best-tolerated and best-validated immune peptides, with substantial clinical use abroad.
- Injection-site reactions are the most commonly reported signal.
