TA-1- also known as Thymosin Alpha-1 – is one of the most researched immune-modulating peptides

TA-1 (Thymosin Alpha-1) is a 28-amino-acid peptide originally isolated from the thymus gland. It’s a

fragment of prothymosin-alpha, a protein involved in regulating immune function.

Search results describe it as a natural immune-enhancing and immune-balancing peptide with

antiviral and anti-inflammatory properties.

How it works:

Enhances T-cell development and activity

Strengthens antiviral defense, including responses to hepatitis, HIV, and influenza

Supports cancer immunotherapy by improving immune surveillance

Balances autoimmune activity without broad immune suppression

Improves outcomes in severe infections, including sepsis

Regulates inflammation and promotes immune resilience
