Frequently Asked Questions
What is Thymosin Alpha-1?
Thymosin Alpha-1 (Tα1) is a synthetic 28-amino-acid peptide identical to the N-terminal fragment of prothymosin alpha. It is studied in preclinical and international clinical models for its role in T-cell maturation and immune signaling via toll-like receptor (TLR9) pathways on dendritic cells. Sold strictly for research purposes in the US.
What is the purity and how is it verified?
Each batch of USA Molecules Thymosin Alpha-1 undergoes third-party purity and identity testing. A batch-specific Certificate of Analysis (COA) is accessible via the QR code on every bottle, confirming lot-level quality verification.
Is Thymosin Alpha-1 approved anywhere in the world?
Thymosin Alpha-1 is marketed internationally as Zadaxin (thymalfasin) in over 35 countries for chronic hepatitis B, hepatitis C, and as an immune adjunct in certain cancer settings. It is not FDA-approved in the United States, and foreign approval does not extend to US marketing or compounding authorization.
How should Thymosin Alpha-1 be stored?
Store in a cool, dry place away from direct light and moisture. Refrigeration is recommended for extended storage. Keep the container tightly sealed when not in use.
Is Thymosin Alpha-1 related to other peptides in the USA Molecules catalog?
Yes — USA Molecules also carries BPC-157 (gastrointestinal and tissue repair research), BAM15 (mitochondrial uncoupling research), Dihexa (cognitive/neurological research), and 5-Amino-1MQ (NNMT inhibition research). Each is sold strictly for laboratory use.
What is the intended use of this product?
