Thymosin Alpha-1: Research Summary and How to Judge a Supplier
Immunomodulatory peptide approved as a medicine in several countries and widely studied in infection research. This profile sets out what is actually published, what a 10mg vial should cost, and the specific documentation to ask for before ordering Thymosin Alpha-1 from any research supplier.

What Thymosin Alpha-1 is
Thymosin alpha-1 is a 28-amino-acid immunomodulatory peptide licensed as a medicine in a number of countries for hepatitis and as an adjuvant, with a substantial clinical literature including sepsis and antiviral studies.
That regulatory status makes the research-market version an unusual case: a well-characterised molecule sold outside the supply chain that generated its evidence. The molecule is understood; the specific vial still needs documentation.
What the evidence base looks like
There is a real published record behind this compound, spread across animal work and a smaller amount of human data, but not enough controlled evidence to support confident claims.
Our library records roughly 145 relevant publications for Thymosin Alpha-1 and grades the evidence as moderate. That grade describes the weight of research, not a judgement about safety or effect, and it is reviewed as new work is published.
Supplier quality: what to check on Thymosin Alpha-1
Acetylation at the N-terminus is essential to activity and is not visible on a basic purity report.
The practical checklist is the same on every product but weighted differently here: a batch-matched certificate of analysis, an identity method appropriate to this molecule rather than purity alone, clear peptide content per 10mg vial, and a supplier that will answer a technical question before taking payment.
Typical UK pricing
The lowest price we currently track for a 10mg vial is £34.95, against a market median nearer £50. Compare on price per milligram rather than per vial, because vial sizes across suppliers are rarely identical.
A listing well below the tracked low is worth investigating rather than celebrating. On this compound the cost of doing it properly is largely analytical, and that is the first thing an unusually cheap supplier stops paying for.
