Tuning the immune system.

Thymosin α-1 is a thymus-derived peptide that helps mature and direct immune cells. Unlike most compounds here, it is an approved medicine in dozens of countries - used for hepatitis and as an immune adjunct.

01
Immune conductor
Promotes T-cell maturation and balanced immune responses.
02
Approved abroad
Marketed as Zadaxin in 30+ countries (not the US).
03
Broad study
Researched in infections, cancer adjuncts and vaccine response.

Where the research focuses.

01
Immune modulation

Supports and balances immune responses - its core, approved role.

02
Hepatitis B & C

An approved indication in several countries.

03
Infection adjunct

Studied alongside standard care in serious infections.

04
Vaccine response

Researched for improving response in immunocompromised patients.

05

A genuine immune drug.

Thymosin α-1 modulates immunity - supporting T-cell function and dampening over-activation - which is why it is approved abroad for hepatitis and used as an adjunct in infections and cancer care.

It drew attention during COVID-19 for immune support, with study quality varying.

Reconstitution calculator

How much diluent to mix into the vial, and the concentration that results. The suggested volume reaches a clean working stock; the calculator does the arithmetic from figures you enter. These describe solution preparation for research handling — not instructions for use in humans or animals.

Suggested reconstitution Reconstitute the 10 mg vial with 2 mL bacteriostatic water → 5.0 mg/mL (5000 mcg/mL)

Concentration = compound ÷ diluent. Volume per aliquot = target ÷ concentration. U-100 units are a volume readout (1 mL = 100 units). Figures are for research solution preparation only — not instructions for use in humans or animals.

Signs of a quality compound

Lyophilised cake or powder
A fine, fluffy white cake — not oily, clumped or discoloured.
Clear reconstitution
Dissolves to a clear, colourless solution with no visible particles or cloudiness.
Batch-specific COA
Independent HPLC purity and mass-spec identity for the exact lot — not a recycled generic PDF.
Intact seal & vacuum
Sealed flip-top vial under vacuum; correct fill; legible batch and storage marking.
Walk away if…
No COA, oily residue, off-colour, partial vacuum, or purity claims with no independent test behind them.
Suspiciously cheap
Pricing far below the market for a well-tested compound usually means skipped testing or underfilled vials.
Regulatory & status
Approved abroad, research in the US.

Thymosin α-1 is approved in more than 30 countries (as Zadaxin) but not by the US FDA, where it is sold as a research material. Among the immune peptides here, it has the strongest clinical footing.
