I'm not sure if this is better suited for r/drugs but I'm trying to find the most cost effective kit to test for fentanyl and alprazolam. I received an interesting batch of bars and i would like to ensure that it's indeed alprazolam. I doubt it is but just a precaution for my safety.
If this doesn't follow the rules I apologize.
There is no reagent test to my knowledge that tests for either. You need to send a sample to Energy Control or to Ecstasy Data. Sorry bro. Hope this helps though.
Edit: never mind u/dabAsorrus is right. Here's a link friend. http://www.sirchie.com/nark20033-fentanyl-reagent.html#.WG332oGp7qA
