What the research says

Thymosin alpha-1 is a 28-amino-acid peptide first isolated from thymus tissue, the organ where T cells mature. Its synthetic form is called thymalfasin. Published research studies it as a modulator of T-cell and dendritic-cell function, including in the context of ageing of the immune system (Simonova et al., Int J Mol Sci 2025). Thymalfasin is sold as a medicine in some countries outside the United States; it has not received FDA approval. Supplied as lyophilized powder in a sealed vial.

Frequently asked questions

How do I know a lot is what it claims to be?

From that lot's certificate of analysis, not from what the supplier asserts. The certificate names the laboratory that took the measurement, the date, the task number, the method and the purity found. PeptoClinic publishes the full reports uncropped, exactly as the laboratory printed them.

What is a certificate of analysis and how do you read one?

It is the report an analytical laboratory issues on a specific sample. Four things are worth checking: which compound it claims to have measured, by what method (HPLC for purity, mass spectrometry for identity), what figure it found, and whether the task number can be verified against the laboratory. A certificate with no verifiable task number is a picture.
