What is Thymosin Alpha-1 and who purchases it wholesale?

Thymosin Alpha-1 (Tα1) is a 28-amino-acid peptide derived from thymosin fraction 5, known for immune modulation and antiviral activity. It is purchased wholesale by compounding pharmacies serving integrative oncology, infectious disease, and general wellness programs.

What documentation is required for Thymosin Alpha-1 API?

Each Tα1 lot should include: HPLC CoA with purity ≥99%, mass spectrometry sequence confirmation (critical for a 28-AA peptide), endotoxin result (<1 EU/mg), residual solvent analysis, SDS, and a chain-of-custody supplier letter identifying the manufacturing facility.

What purity should wholesale Thymosin Alpha-1 meet?

Thymosin Alpha-1 API must meet HPLC purity ≥99%. At 28 amino acids, sequence verification via mass spectrometry is essential — truncation variants and synthesis byproducts are common quality risks in longer-chain synthetic peptides.

Is Thymosin Alpha-1 on the FDA bulk drug substances list?

The FDA has historically taken a permissive stance on compounded Thymosin Alpha-1, particularly during periods of shortage. However, regulatory status continues to evolve. Facilities should consult current FDA guidance and their state board before compounding.

What vial configurations are available for wholesale Tα1?

Thymosin Alpha-1 is typically available in 1.5mg and 5mg vials, consistent with standard clinical dosing protocols. Bulk API is available for high-volume compounding programs. Contact our wholesale team for current availability.
