How testing works
Pick your tests
Choose from the price list, or email us about a compound we don't list. Each price covers purity and identity.
Mail your sample
Ship it to our lab at 525 Washington Blvd, Jersey City. Use tracked shipping and put your order email inside the package.
Get your certificate
We email you a Certificate of Analysis and post the result here, where anyone can look it up by lot number.
Why test with us
Label claims and online reviews tell you what a vendor wants you to believe. A lab report tells you what the vial holds.
- We don't sell what we test
- We make no peptides or supplements, so we have no stake in which vendor comes out ahead.
- Numbers you can compare
- Each report gives purity as a percentage and measured content in milligrams, next to an identity result. You can line two vendors up side by side.
- Published methods, trained chemists
- We run methods from the scientific literature on professional-grade HPLC and LC-MS instruments. Trained analytical chemists run each test and review the data.
- Quick turnaround
- Our lab is in New Jersey. U.S. samples reach us in a day or two and we report as soon as the work is done.
- Every certificate is public
- Each result gets a permanent page. Anyone with the lot number or test ID can look it up and link to it.
We buy from vendors without telling them
We order products on the open market the same way you do, then test them. Vendors don't know the order came from us and get no say in the report. We publish the data as measured, and you decide what it means.
