— About this compound
Thymosin Alpha-1 (Tα1) is a 28-amino-acid N-acetylated peptide derived from prothymosin alpha (ProTα). Among the family of thymic peptides, Tα1 is the most extensively characterized in the published immunology and infectious-disease research literature.
The peptide is identical in sequence across mammalian species, suggesting strong evolutionary conservation. In approved clinical use abroad it is administered subcutaneously; in research contexts it is most commonly investigated for effects on T-cell maturation, dendritic-cell function, and innate-immune signaling.
— Mechanism
Toll-like receptor 9 (TLR9) and MyD88-dependent signaling pathway activation has been reported as the dominant proximal mechanism. Downstream effects include dendritic-cell maturation, enhanced Th1 cytokine production, and modulation of regulatory T-cell populations in preclinical models.
— How it’s made
Every Nexa batch follows the same documented path. Five steps, every one verifiable.
01
Sourcing
Active pharmaceutical ingredient sourced from FDA-registered manufacturers. Identity confirmed against reference standard before any compounding begins.
02
Compounding
Lyophilized in a cleanroom at our US facility. The powder format gives ≥24 months sealed stability — no cold-chain shipping required.
03
Verification
Reverse-phase HPLC-UV (UV/MS for higher-MW peptides) confirms identity and purity for every batch before it leaves the lab. The chromatogram is archived.
04
Release
No batch ships until an independent laboratory has returned its identity and purity results and the certificate is published in the COA library.
05
Dispatch
Sealed vials with a QR code on the label that opens the COA library. Order before 2pm CT Monday–Thursday for same-day dispatch. UPS Ground, tracked + insured.
