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.
