About Thymosin Alpha-1
About Thymosin Alpha-1
Origin Peptides Thymosin Alpha-1 5mg Vial is a 5 mg lyophilised (freeze-dried) single compound research vial from Origin Peptides, sealed under nitrogen, batch numbered and cold stored. Supplied strictly for laboratory research; not for human or veterinary use.
Handling and storage
Vials are shipped lyophilised and should go into a -20C freezer on arrival, protected from light. Lyophilised peptide is stable for months when kept cold, dry and sealed; once a vial is opened or reconstituted it should be handled according to your laboratory's protocols. Bacteriostatic water, syringes and other lab supplies are sold separately. No reconstitution or usage guidance is given on this site.

What the published research says
Thymosin alpha-1 is a 28-amino-acid peptide originally isolated from thymic tissue. It acts on toll-like receptors on dendritic cells and modulates T-cell maturation.
It is one of the few peptides in this range with a licensed pharmaceutical counterpart: thymalfasin (Zadaxin) is approved in more than 30 countries for hepatitis B and as a vaccine adjuvant, with a published record in chronic hepatitis B and C trials and in sepsis (Wu and colleagues, Critical Care, 2013). During 2020 it was studied in COVID-19 in China and Italy with mixed results.
The clinical record belongs to the licensed medicine. The research material sold here is not that product.
Research profile
The research profile card in the image gallery scores five areas of the published literature out of five (tissue repair, recovery and sleep, growth and muscle, fat loss and metabolic, cognition and longevity). It reflects where the studies have concentrated, not a claim about effects. Thymosin Alpha-1 sits in the Cellular & Longevity category of the Origin Peptides range, which is colour coded on the vial band and the card.
Lab testing
Every batch of Thymosin Alpha-1 is tested by an independent laboratory before it is released, with identity confirmed by HPLC or LC-MS and the purity stated on the certificate.
Each vial carries a batch number. The certificate of analysis is published on the Lab Testing page, so you can match the report to the number on your vial.

Questions
Is it legal to buy in the UK? Research peptides of this kind are not controlled substances under the Misuse of Drugs Act 1971, so buying and holding the material for laboratory research is lawful. Selling or advertising it for human use would make it an unlicensed medicine under MHRA rules, which is why this listing carries no usage guidance and every item is labelled research use only.
Is the vial reconstituted? No. Every Origin Peptides vial is supplied as lyophilised powder with the stated milligram content, which is the standard format for research peptides because it is more stable than solution. Reconstitution is a laboratory step and is not described here.
How is it shipped? Orders placed before the daily cut off are despatched the same working day by tracked delivery, usually arriving within two to three working days for UK addresses, with a next day upgrade available at checkout. Parcels are plain and unbranded. Vials travel lyophilised, which tolerates transit at ambient temperature; refrigerate or freeze on arrival.
Are these compounds prohibited in sport? Most peptides in this range are prohibited by WADA, either under S0 (non-approved substances) or S2 (peptide hormones and growth factors). Anyone subject to anti-doping rules should treat the whole category as prohibited.
Research use only. This product is supplied strictly for laboratory and research purposes and is not for human or veterinary use. It is not a medicine, not a food supplement and not intended to diagnose, treat, cure or prevent any disease. Sold to persons aged 18 or over only.
