How to read this report

Same six keys on every Astramide product page. Only the values change.
1Lot numberMatch it to the number printed on your vial. If they differ, this report is not for your vial.
2IdentityMass spectrometry confirms the molecule is the one on the label. It conforms or it does not. There is no partial result.
3Chromatographic purityThe share of the material that is the target peptide. A purity figure quoted without a method is not a purity figure.
4Net contentHow much peptide is in the vial, as measured by the laboratory. A different question from purity.
5EndotoxinMeasured against a ceiling, not a floor. Sensitivity differs by laboratory, so results are not compared across labs.
6Laboratory, method, dateWho ran it, on what instrument, and when. A report with no named laboratory or no date is not a report.

What does this record cover?

One lot, and one lot only: lot SD-260725-1, in the 10 mg vial. Results from one lot do not carry over to the next. Match the lot number printed on your vial to the lot number on this page before you rely on any figure here. If the two differ, this is not the report for your vial.

Who ran the testing?

Optiq Health Labs ran the analysis. Astramide does not test its own material and does not report its own numbers. How we test sets out which laboratories we use and what each method measures.

Where is the original document?

The Certificate of Analysis above is the laboratory’s own PDF, served whole and downloadable. It is not a screenshot, a transcription or a summary. Every figure on this page is read from it. Every lot we have tested is published the same way, including the ones we rejected.

Where can this compound be found?
