TL;DR

Thymosin Alpha-1 is a naturally occurring peptide studied in immune-function research for its role in modulating immune responses. It has been used clinically in some regions and has human data, though evidence for many applications remains under evaluation. It is provided as a research compound for laboratory and educational reference only.

What is Thymosin Alpha-1?

Thymosin Alpha-1 (Tα1) is a 28-amino acid peptide naturally produced by the thymus gland. It plays a crucial role in immune system development and function, particularly in T-cell maturation and function.

Tα1 is approved in over 35 countries for conditions including hepatitis B, hepatitis C, and as an immune adjuvant. It’s one of the most clinically validated immune-modulating peptides available.

The 5mg vial provides 1-3 doses at typical research amounts.
