Instant Strip LLC is a Michigan based company that wants to help people test for the deadly opioid Fentanyl. As an official distributor for manufacturer BTNX, Inc. we offer the easiest and most accurate test strip on the market. Fentanyl has been found in counterfeit prescription pills, heroin, cocaine, and MDMA and was the cause of 31% of all drug overdose deaths in the United States in 2016. Completely undetectable by human sight, touch, smell, or taste, Fentanyl has proven to be the most deadly opioid with a rapid increase in presence. The only way to ever know if there is fentanyl in a sample is to test using these strips. The goal of the test device is not to determine whether the drug is safe to consume or fentanyl-free, but rather to make people think twice before consuming a fentanyl-positive sample. We do not promote people to use drugs once a negative result is determined, in fact we aim to be a constant reminder that drugs are dangerous no matter the result of fentanyl-testing.
