COMMON QUESTIONS.
§ 08 · FAQWhat conditions is Thymosin Alpha-1 approved for?
It's approved in 35+ countries for Hepatitis B/C and as cancer adjunct therapy. Brand name is Zadaxin. Not FDA-approved in the US but available for research.
How does it help cancer patients?
Research shows it enhances immune surveillance against cancer cells, improves quality of life, and may reduce chemotherapy side effects. Used alongside conventional treatment, not as replacement.
Can healthy people use it for immune support?
Some use it for general immune optimization or during illness. Research supports immune enhancement in healthy subjects, though it's primarily studied in immunocompromised patients.
Is it the same as thymosin beta-4 (TB-500)?
No, they're different peptides with different functions. Thymosin Alpha-1 is primarily immune-modulating. Thymosin Beta-4 (TB-500) is for tissue healing. Both derive from thymus but work differently.
