About

What is this?
testing.trans.diy is a public database of chromatograph testing results for products sold by DIY suppliers. Samples are submitted to independent analytical labs, and results are entered here by admins after verification. Suppliers receive a status rating based on the consistency of their tested products. We work INDEPENDENTLY of suppliers, we do not host the tests that suppliers have purchased for themselves, as that is unreliable.

Suppliers vs. Labs

Suppliers are the sources selling the compounds — pharmacies, resellers, homebrewers. These are the entities being tested. Each supplier receives a status rating.

Labs are the independent analytical laboratories that perform the actual chromatograph testing. They are listed for transparency about who ran each test, but are not themselves being rated.

How It Works

Samples of a supplier's product are submitted to an independent lab for HPLC (High-Performance Liquid Chromatography) testing. The lab produces a chromatograph showing the compound's composition and concentration.

Results are recorded as mg/mL values with an assay percentage calculated from the expected vs. actual concentration. An assay of 100% means the sample exactly matches its labeled concentration. The supplier's status is updated based on test consistency over time.
