Research Considerations

Cautions

Thymosin alpha-1 is approved in some countries but not in the US; research-grade material is not a substitute for prescribed Zadaxin.
Immunomodulators can interact with autoimmune conditions and immunosuppressive therapy; the mechanism is bidirectional.
Source only COA-verified material and verify identity, as thymosin peptides are commonly mislabeled.
