Thymosin Alpha-1 vs Thymalin
Research material comparison: purity standards, available formats, molecular data, batch COA documentation, and regulatory status. For in vitro research use only.
| Attribute | Thymosin Alpha-1 | Thymalin |
|---|---|---|
| Category | Immune Modulator | Immune / Anti-Aging |
| Evidence Rating | C — Phase I–II Clinical Trials | C — Early Human or Mixed Evidence |
| Clinical Status | Approved in 35+ countries (Zadaxin); FDA orphan drug designation; not FDA-approved in the US | Approved medication in Russia for immunodeficiency. Used clinically since 1982. Western clinical evidence is limited. |
| Mechanism | Ta1 (C129H215N33O55) activates Toll-like Receptors TLR2 and TLR9 on immune cells, triggering the MyD88 and NF-kB signaling pathways to put the immune system on alert without destructive inflammation. Key mechanism: increases MHC Class I expression, unmasking hidden viruses and cancer cells for immun... | Thymalin contains short bioregulatory peptides (primarily di- and tripeptides including Glu-Trp) derived from thymic tissue. These peptides are proposed to interact with DNA regulatory sequences, modulating gene expression related to immune function. Specifically, thymalin is thought to promote thym... |
