Thymosin Alpha-1 (Tα1) Research Peptide
What exactly is Thymosin Alpha-1(TA)?
Thymosin Alpha-1 is a peptide first isolated from thymosin fraction 5 in the 1970s. So, researchers have studied it for decades. It is a 28-residue acetylated peptide. The sequence is fully known and synthetically reproducible.
Molecular formula: C₁₂₉H₂₁₅N₃₃O₅₅ · MW: 3108.3 g/mol
However, not all commercial sources are equal. Purity matters a lot in peptide research. That is why we publish our COA from every run.
Is this Thymosin Alpha-1 third-party tested by Janoshik?
Yes. Every batch gets tested at Janoshik Analytical an independent European lab. So, you are not just taking our word for it. First, we send a sample from the production batch. Next, Janoshik runs HPLC and mass spec. Finally, they issue a COA that you can download.
Our latest result: 99.36% purity. Also, mass spec confirms the correct molecular weight. No assumptions. No guessing.

How should Thymosin Alpha-1 be stored in a lab setting?
Store lyophilized powder at −20°C. Keep it dry. Light and moisture degrade the peptide fast. So, use a sealed vial with desiccant.
But once reconstituted, store at +4°C. Use within 7–14 days. Also, avoid repeated freeze-thaw cycles. Therefore, aliquot before freezing if you plan multiple uses.
Where can researchers buy Thymosin Alpha-1 with a verified COA?
You can order directly from globalpeptidesofficial.com. So, no middlemen. No unverified bulk resellers. Each order includes a Janoshik COA matched to that specific batch lot number.
Also, we ship in temperature-appropriate packaging. However, always verify your local regulations for peptide research imports before ordering.
