— About this compound

Thymosin Alpha-1

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

How it's been studied

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

From compound to your shelf

Every Nexa batch follows the same documented path. Five steps, every one verifiable.

01

Sourcing

Compound starts as a research-grade API.

Active pharmaceutical ingredient sourced from FDA-registered manufacturers. Identity confirmed against reference standard before any compounding begins.

02

Compounding

Sterile-filled in a US cleanroom.

Lyophilized in a cleanroom at our US facility. The powder format gives ≥24 months sealed stability — no cold-chain shipping required.

03

Verification

Every batch HPLC-tested.

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

The batch is released against an independent assay.

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

Ships from San Antonio in 48 hours.

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.
