Testing
Most suppliers pass on the certificate their manufacturer gave them. We do not consider that evidence. Every batch we sell is analysed independently after it reaches us, and both results are published side by side.
Batch verification
Enter the batch number printed on your vial. You will see the analysis for that exact batch — not a generic document for the product line.
No batches are published yet. Our first analyses are in progress and will appear here as they clear. This page will always show every batch we have ever sold, including withdrawn ones.
Supplied with the batch by the synthesis facility. It states purity by HPLC and confirms identity by mass spectrometry. We publish it in full, unedited, including the manufacturer's name.
We draw a sample from the batch on arrival and send it to a UK laboratory that has no relationship with the manufacturer and no interest in the result. That analysis is published alongside the first.
If the two disagree, the batch does not go on sale. We publish the discrepancy anyway, so you can see what we rejected and why. A supplier who only ever shows you passes is showing you a selection, not a record.
Worth knowing whoever you buy from. A certificate that is missing these is not evidence of anything.
| Element | Why it matters |
|---|---|
| Batch number | Ties the document to physical vials. Without it the certificate describes nothing. |
| Date of analysis | A certificate from three years ago says nothing about this batch. |
| Named laboratory | An unnamed lab cannot be checked or held to anything. |
| HPLC chromatogram | The actual trace, not a summary line. A stated percentage with no chromatogram is a claim. |
| Mass spec confirmation | Purity says how much of one thing is present. Identity says whether it is the right thing. |
| Method stated | Different methods give different numbers. A result without a method is not comparable. |
If a supplier will not show you the chromatogram, they are asking you to trust a number they typed.
