How to verify Thymosin Alpha-1 is authentic
Step-by-step guide to verifying your Thymosin Alpha-1 is genuine: checking the COA, matching the batch number, and downloading from the product page.
Step 1: Locate the batch number
Every Peptify Thymosin Alpha-1 vial has a batch (lot) number printed on the label. Note this number down — it should match the Certificate of Analysis published on the product page for that specific batch.
Step 2: Download the COA from the product page
The batch-specific COA for your Thymosin Alpha-1 is downloadable directly from the product page on peptifyuk.com. This is the most reliable verification method because the document is hosted under our control, tied to the batch number, and includes the original HPLC chromatogram image plus mass spectrometry data.
If a supplier does not publish batch-specific COAs or only provides a generic purity claim, that is a significant red flag.
Step 3: Check the HPLC peak
On the COA, look at the HPLC chromatogram. A genuine Thymosin Alpha-1 sample should show a single dominant peak at the expected retention time, with purity >99% (peak area). The mass spectrometry section should confirm the molecular weight matches the theoretical mass of Thymosin Alpha-1.
Any chromatogram with multiple large peaks, or where the purity percentage looks inconsistent with the visible peak, should prompt you to contact the supplier for clarification.

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.
