How to verify Thymalin is authentic
Step-by-step guide to verifying your Thymalin is genuine: checking the COA, matching the batch number, and downloading from the product page.
Step 1: Locate the batch number
Every Peptify Thymalin 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 Thymalin 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 Thymalin 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 Thymalin.
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
What is Thymalin used for in research?
Thymalin is studied for its ability to restore thymus function and regulate immune responses, particularly in aging-related immune decline.
How does Thymalin differ from Thymosin Alpha-1?
Thymalin is a multi-peptide thymic extract studied in the broader bioregulator literature, while Thymosin Alpha-1 is a single 28-amino-acid peptide with a defined sequence. Researchers select between them based on the specificity required for their protocol.
What purity standard does Peptify Thymalin meet?
Peptify Thymalin is 99%+ HPLC-verified with an independent third-party Certificate of Analysis from Janoshik Analytical, downloadable directly from the product page.
