Description
Thymosin Alpha-1 is a 28-amino-acid peptide originally isolated from the thymus and one of the most studied immune peptides in the world. Limitless Life Nootropics supplies it in 5mg and 10mg vials, made in the USA.
What Is Thymosin Alpha-1?
The peptide was first isolated in 1977 by Allan Goldstein and colleagues from a thymus extract known as Thymosin Fraction 5. It is derived from a larger precursor protein, prothymosin alpha, and carries an acetyl group at its N-terminus.
Research has focused on its effects on T-cell maturation, dendritic cell function and Toll-like receptor signaling. It has been studied in models of viral infection, vaccine response and immune aging, and a synthetic version has been approved as a medicine in a number of countries, giving it an unusually deep body of literature.
It is available in Premium lyophilized grade in 5mg and 10mg sizes.
Key Research Areas
The scientific literature describes this peptide across several areas of investigation:
- T-cell maturation and differentiation
- Toll-like receptor and dendritic cell signaling
- Vaccine response models
- Immune aging (immunosenescence)
- Viral infection models
Researchers can review peer-reviewed studies on Thymosin Alpha 1 through the National Library of Medicine (PubMed) database.
