A different evidence class from most of this catalogue
Thymosin Alpha-1 is a 28-residue peptide produced by the thymus gland.1 It’s marketed clinically as thymalfasin in some jurisdictions,2, which is unusual for anything in this catalogue.
That approval history means the published literature on it is more substantial than average for a research peptide. It doesn’t make it approved in Canada, and we supply it for research use only.
Thymosin Alpha-1 purity and testing
Medutest returned 98.95%. The report goes up in full, not as a claim. Available in 10mg.
HPLC purity covers identity and purity of the vial contents, not sterility, endotoxin or heavy metals.
Thymosin Alpha-1 is not Thymalin
Thymosin Alpha-1 and Thymalin are both thymic peptides and get confused constantly. They’re different compounds with different molecular weights and different literatures.
If your protocol specifies one, check which. We stock Thymosin Alpha-1 and not Thymalin.

Thymosin Alpha-1: frequently asked questions
Direct answers on identity, testing, cost and the Canadian regulatory position. We do not publish dosing or effect claims, and one of the questions below explains why.
What is Thymosin Alpha-1?
Thymosin Alpha-1 is a research compound supplied for laboratory research use only. Its verified identity data is a molecular weight of 3108.3 g/mol, CAS 62304-98-7, PubChem CID 16130571. It is listed under Immune Support and available in 10mg.
Is Thymosin Alpha-1 safe?
No safety profile has been established for Thymosin Alpha-1, and nothing on this site should be read as saying otherwise. What we can tell you is narrower and verifiable: this lot was assayed at 98.95% by Medutest and we hold the full report and send it on request. An HPLC purity result is a statement about identity and purity in a tested lot. It does not measure sterility, endotoxin or heavy metals, and it is not a safety assessment. Health Canada has published advisories on unauthorized injectable peptides, and you should read the research use disclaimer before ordering.
Is Thymosin Alpha-1 legal in Canada?
Health Canada regulates injectable peptides as drugs, and it has stated in writing that labelling one “for research use only” does not remove it from that regulation. The regulator has published advisories naming specific compounds, seized product from Canadian sellers, and obtained a court injunction against at least one seller. Most suppliers present research use labelling as though it settles the question. On the regulator’s own published statements, it does not, and we would rather say so than let you assume otherwise. Read the disclaimer in full.
Is Thymosin Alpha-1 a steroid?
No. Thymosin Alpha-1 is a peptide, not an anabolic steroid, and the two are different classes of molecule with different structures. Its molecular weight is 3108.3 g/mol. Steroids share a four-ring carbon skeleton; peptides are chains of amino acids.
How to reconstitute Thymosin Alpha-1?
Use the peptide calculator: enter the vial’s total mass and your target concentration, and it returns the volume of bacteriostatic water to add. That is arithmetic, not a dosing instruction, and it is the step people most often get wrong. Reconstituted material has a much shorter usable life than sealed powder.
Is Thymosin Alpha-1 third party tested?
Yes. This lot was assayed at 98.95% by Medutest, and we hold the full report and send it on request rather than compressing it into a badge. The batch reference travels on the packing slip, which is what lets you match the vial you received to the report on the lab results index. A purity figure with no batch behind it tells you nothing about your vial.
Where to buy Thymosin Alpha-1 in Canada?
Here, shipped across Canada, with the batch certificate reference on the packing slip. The thing worth comparing between Canadian suppliers is not price but what each one publishes: whether a third-party report exists, whether it is shown in full or reduced to a percentage, and whether it can be tied to the lot you received.
How much does Thymosin Alpha-1 cost?
Prices are on the product page in Canadian dollars, and this product is offered in 10mg. Compare price per milligram rather than price per vial, because strengths differ between suppliers and a cheaper vial is often a smaller one. A vial with no assay and no batch reference is not the same product at a lower price, it is a different proposition.
What does Thymosin Alpha-1 do?
We do not answer that here, and the reason is not evasiveness. Describing what a compound does, in a shop that sells it, is a therapeutic claim, and that is the line between describing a research compound and marketing an unlicensed drug. What we publish instead is identity, purity, the testing laboratory and the limits of the assay. Where published research exists, the product page cites it and links the source so you can read it yourself rather than take our summary of it.
Thymosin Alpha-1 vs LL-37?
They are different compounds with different identity data and different research literature, and neither substitutes for the other. The comparison worth making is on what each one is and what evidence exists for it, which is set out on both product pages. See LL-37.
