Thymosin Alpha-1 is a peptide originally identified in thymus tissue, and the Celyfe compound library classes it as an immune-modulating peptide studied for its role in T-cell function. It is a regulated compound and it is not carried in any Celyfe pen.
What is Thymosin Alpha-1?
Thymosin Alpha-1 is a naturally occurring peptide first isolated from thymus tissue. Like TB-500's parent protein thymosin beta-4, it belongs to the thymosin family, but the two are different peptides with different research literatures. The Celyfe library classes it as a peptide with the mechanism note: peptide studied in immune-modulation and T-cell research. As a peptide it is a regulated compound, which is why this page uses informational framing only.
Research peptides are made by solid-phase peptide synthesis and characterised by mass spectrometry for identity and HPLC for purity. The guide What are research peptides? explains the chemistry that applies to Thymosin Alpha-1 as much as to the peptides Celyfe does carry.
Is Thymosin Alpha-1 in a Celyfe pen?
No. The peptides Celyfe carries are BPC-157, TB-500, GHK-Cu and KPV in the WOLVERINE, GLOW and KLOW pens, all on sale now. Thymosin Alpha-1 is not in any of them, Celyfe does not currently sell it as a product, and Celyfe lists no Thymosin Alpha-1 reference, so this page makes no statement about research findings for the peptide.
Legal position in the UK
Research peptides are not controlled drugs in the UK and can be bought and possessed for laboratory research. What UK law regulates, through the Human Medicines Regulations 2012 and the MHRA, is selling or marketing a substance as a medicine for human use. The guide Are peptides legal in the UK? sets out that framework as general information, not legal advice.
Key takeaways
- •Thymosin Alpha-1 is a peptide.
- •Library note: Peptide studied in immune-modulation and T-cell research.
- •Library entry: not currently carried in a Celyfe pen.
- •Thymosin Alpha-1 is a regulated compound - this page is educational, not medical advice.
This page is informational and not medical advice. Thymosin Alpha-1 is a regulated compound. Celyfe pens are supplied strictly for in-vitro laboratory research and nothing here is guidance on use in humans or animals.
