How to store Thymosin Alpha-1
Practical storage protocol for Thymosin Alpha-1: temperature, light, reconstitution timing, and shelf life in a research setting.
Lyophilised (freeze-dried) storage
Unreconstituted Thymosin Alpha-1, like most research peptides, is stable when stored in its original sealed vial at -20°C for long-term storage. For short-term use (under 3 months), refrigeration at 2-8°C is acceptable. The vial must be protected from direct light and moisture.
Peptify dispatches Thymosin Alpha-1 in temperature-tolerant packaging from the UK, usually arriving within 24-48 hours of dispatch.
After reconstitution
Once Thymosin Alpha-1 is reconstituted with bacteriostatic water (BAC water, 0.9% benzyl alcohol), the solution should be stored at 2-8°C (refrigerated) and used within 28 days. Bacteriostatic water's preservative system inhibits microbial growth for roughly four weeks after first puncture — significantly longer than sterile water, which must be used immediately.
Avoid freeze-thaw cycles. Never leave the vial at room temperature for extended periods, and keep it in its original rubber-stoppered vial to minimise contamination risk.
Shelf life and quality verification
Peptify publishes a batch-specific expiry date on every Thymosin Alpha-1 COA, alongside HPLC chromatogram data and mass spectrometry confirmation. The full Certificate of Analysis for your specific batch is downloadable from the product page.

Frequently asked questions
How does Thymosin Alpha-1 differ from Thymalin?
Thymosin Alpha-1 is a specific 28-amino acid peptide that directly enhances T-cell maturation and function, while Thymalin is a broader thymic extract.
What does the published research describe?
Published preclinical work has examined Thymosin Alpha-1's role in T-cell maturation, dendritic cell signalling, and innate immune-response endpoints. It has a long-established research literature in immune-modulation studies.
What purity does Peptify supply?
Peptify Thymosin Alpha-1 is 99%+ HPLC-verified. Every batch ships with a downloadable Janoshik Analytical Certificate of Analysis matching the lot number printed on the vial.
