Lab Results
Check our testing before you buy.
Every tested compound in the catalog has a published report from Janoshik Analytical, an independent third-party lab. Below are the actual measured results, what each test does and does not cover, and how to confirm a report is genuine.

Starter kits and multi-vial packs contain the same vials, so they share the report for their compound. Each report reflects the batch the lab tested. Documentation for the exact lot you received is available on request, as described on our Quality Standards page.
What the reports cover
What these tests show, and what they don't.
✓ Covered by the report
Identity
The report names the compound the lab found in the vial. Our Retatrutide sample was submitted as a blind test against semaglutide, tirzepatide, and retatrutide, so the lab identified it without being told what to expect.
✓ Covered by the report
Quantity
The lab measures how many milligrams are actually in the vial, so you can compare it with the label. Every published report measured at or above the labeled amount.
✓ Covered by the report
Purity
Purity is measured by HPLC (high-performance liquid chromatography) and reported to three decimal places, rather than rounded up to a marketing number.
✕ Not covered by these reports
Sterility and endotoxins
These reports do not test sterility or endotoxin levels. Our products are supplied as research materials, not as sterile pharmaceutical products, and we would rather tell you that plainly than let a purity number imply more than it shows.
Confirm it yourself
How to check a report is genuine.
Every Janoshik report carries a unique verification key. Entering that key at janoshik.com/verify pulls up the original report directly from the lab, so you can confirm that the document we published matches the one they issued.
Email us with the compound you want to check and we will send you its key. Anyone can ask, and you don't need to place an order first.
