EZ Test kit tests for the presence of GHB.
The popularity of GHB has skyrocketed over the last couple of years, leading to a ban on the sale of certain precursors that are needed to make this substance. As a result you could be buying untreated GBL, an industrial chemical that is used as a sticker remover. Ingesting pure GBL can be very dangerous to your health. EZ Test for GHB enables to quickly identify the presence of GHB in a sample. It does NOT react to GBL.
All EZ tests use a chemical reagent absorbed in silica gel, which is held inside a glass ampoule.
When a sample is added to these chemicals inside the ampoule if a reaction occurs a colour change will take place. This colour should be compared to the colour chart included on the instructions within the package, to give an indication as what could be in the sample.
If your unopened ampoule is damaged please contact the retailer it was purchased from.
