How to read a Janoshik report
What a certificate of analysis from Janoshik contains, how to verify one with its key, and the four public reports behind the products named on this site.
What a report is
Janoshik Analytical is an independent laboratory. Clients send it a sample, and it sends back a certificate of analysis: a short report with the name of the compound, the method used, the measured result, a task number, a date and a verification key. The report describes the sample the laboratory received, and nothing else.
What the report contains
A typical report has three measurements. Purity by HPLC tells how much of the detected material is the named compound; HPLC stands for high-performance liquid chromatography, a method that separates a sample into its parts. Identity by mass spectrometry confirms that the molecule weighs what the named compound should weigh. Content gives the amount found, in milligrams for a vial or in milligrams per millilitre for a solution such as a pen. Some reports add an endotoxin test, which looks for bacterial residues.
How to verify a report
Each report carries a 12-character verification key. Entering that key on verify.janoshik.com shows the laboratory's own copy of the report. If the copy on the site matches the PDF in hand (compound, date, task number, purity and content), the PDF is genuine. If the key opens nothing, or the details differ, the PDF should be treated as unverified. [1]

Red flags worth knowing: a client name or logo that looks edited, a key that opens nothing, a report older than a year presented for a recent batch, and a purity figure quoted without any key. For other products, lab documentation is available from the supplier.

What this page is, and is not
This page explains what published studies found. That is all it is. It is not medical advice, and it is not instructions for using anything. Nothing here is meant to find, treat, cure or stop any illness. The compounds discussed on this site are not approved medicines in the EU or the UK. Research compounds are sold for laboratory use only, not for use in humans or animals. A study tells you what happened to the people in it. It does not tell you what would happen to you. Talk to a doctor. This page is published by AuraVia Research Ltd, which sells research compounds.
