Thymosin Alpha-1 FAQ: Your Questions Answered
The questions below are the ones that come up specifically about Thymosin Alpha-1, rather than general peptide questions that apply to everything.
Overview
People ask if it is the same as Zadaxin (yes), how its immune role is studied, and whether it is light-sensitive (no).
What Thymosin Alpha-1 actually is
A 28-part peptide the thymus gland makes naturally, with one of the deepest research records of any immune peptide. Studied for how it helps T-cells mature and how the immune system responds to infection. The clinical version is called Zadaxin.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Thymosin Alpha-1 — common questions
Is Thymosin Alpha-1 the same as Zadaxin?
Zadaxin is the clinical formulation of the same 28-residue thymic peptide. The research-grade material is the identical sequence handled for laboratory study.
How is its immune role studied?
It is examined in research models for effects on T-cell maturation and immune signalling pathways, including innate-immune receptors, rather than as a direct effector.
Why is it acetylated?
The natural peptide carries an N-terminal acetyl group, which its COA should confirm; an unacetylated form is a characteristic impurity to check for.
Is it light- or oxygen-sensitive?
No. It lacks methionine, cysteine and tryptophan, so it does not carry the oxidation vulnerability that forces light protection on some other peptides. Its slow route is deamidation.
What Thymosin Alpha-1 is studied for
Studied for a role in the maturation and function of T-cells in immune research models.
Examined around innate immune signalling pathways, including Toll-like-receptor involvement, in preclinical work.
Investigated in models of immune response to infection and as a research adjuvant.
