Most suppliers in this space ask you to trust a percentage printed on a page. The only figure worth anything is one you can check yourself, at the laboratory, without going through us.
Our assays are run by Janoshik Analytical, an independent testing laboratory used widely across the research compound trade. We don't run our own tests and we don't publish in-house numbers. Janoshik issues a unique verification key with every report; entering that key at janoshik.com/verify returns the original document from the lab's own records.
For single compounds we order a peptide vial assessment, which reports the quantity found in the vial and its chromatographic purity. For blends we order component identification and amount, so each peptide in the vial is confirmed and quantified separately. For GLP-family compounds we order the blind panel: the lab screens the sample against semaglutide, tirzepatide and retatrutide without being told which one to expect, so identity is confirmed rather than assumed.
These are content and purity assays. They are not sterility testing, endotoxin testing, heavy metals screening or stability testing, and we don't claim otherwise. Each batch report on this site lists exactly the measurements the laboratory returned for that batch.
Some items in the catalogue don't currently have an independent report for the batch in stock. Their product pages say certificate pending and carry no purity claim, because we don't have one to give. The batch reports page lists exactly which ones are awaiting assay.
We make no accreditation claim of our own. Aurelius Labs is a supplier, not a laboratory, and we hold no ISO certification. Questions about Janoshik's own methods and accreditation are best directed to the laboratory.
