No certificates are published yet.
Each batch's certificate appears here, with its own page, as soon as it is loaded. Until then, ask us for the certificate of the batch you are buying.
Finding your batch
Look on the vial label, on the box and on the delivery note: the batch number is printed on all three. Type it into the search, or filter by product and strength. If the certificate's number differs from any of the three, stop there: put the box aside, unopened if possible, and send us the delivery note number through the contact page.
What a batch page shows
| Line | What it tells you |
|---|---|
| Product, strength, batch number | Which material, and which production lot |
| Manufactured; expiry or retest date | How old the batch is, and until when the manufacturer stands by the results |
| HPLC purity | The main peak's share of the peptide material, from the chromatogram |
| Identity by mass spectrometry | Whether the measured mass agrees with the mass calculated from the sequence |
| Net peptide content, water content | How much of the powder is peptide, where the manufacturer measured it |
| Endotoxin, appearance | Reported where they were tested |
| Tested by | The laboratory that ran the tests |
| Documents | The certificate as a PDF, and an independent laboratory's report where one exists |
Where a test was not run, the page says "not tested". No field is left blank, and no result is borrowed from another batch.
What the status means
- Released: the batch passed release and is being supplied.
- Advisory: the batch carries a note you should read before using stock from it. The note is on the batch page.
- Withdrawn: supply of the batch has stopped. The page remains, with the reason, for anyone who still holds stock from it.
Whose certificates these are
The manufacturer issues each certificate at the point it releases the batch. We are not the manufacturer, and the PDF you download is the manufacturer's own document, unchanged. An independent laboratory's report, where a batch has one, is filed beside the certificate and marked as independent. How batches are tested explains what each method proves and what it does not.
What a certificate does not tell you
A certificate records the batch on the day of analysis. How a box was kept after that is a separate question, answered by storage and the delivery note: see shipping and storage. And no purity figure, however high, makes a research-grade product fit for use in people or animals. Research-grade material is for laboratory research only.
For cosmetic manufacturers
GHK-Cu and Acetyl Octapeptide-3 bought as cosmetic ingredients are certified per lot in the same way, so your goods-in check can match the lot number on the container to its certificate. What else a cosmetic registration file for the Egyptian Drug Authority (EDA) contains is set out in registering a cosmetic product in Egypt.
Questions buyers ask
- Can I see the certificate before I order?
Not yet: until the library is online, the certificate for your batch comes with the goods.
- Does a certificate come with every delivery?
Yes. Every batch in a carton is covered by its certificate of analysis, and the delivery note lists the same batch numbers.
- How do I check that a certificate is genuine?
Four checks take a few minutes. The batch number agrees with your label. The manufacture date comes before the expiry date, and both are plausible. A laboratory is named. The measured mass agrees with the mass calculated from the sequence, which each product page in the catalogue gives with the formula. How to read a certificate of analysis takes a certificate line by line.
