Did it come from someone’s pill bottle from the pharmacy? If not, and you can’t verify, you would need to send it off to the lab and pay for a GC/MS (gas chromatography-mass spectrometry) test. Or, don’t buy pressed benzodiazepines pills, but if you do, buy reagent test kits. Benzodiazepines are notoriously hard to identify with at home reagents (especially alprazolam and clonazepam) there are literally thousands of them that people by and press with whatever you it to look like. Some people will also poison you with fentanyl RC’s if you don’t test illicit pills. Don’t trust shit. Buy your own RC benzodiazepines from a trusted vendor if you like them a lot. It’s too scary to trust anyone these days.
Test for fentanyl though.
