Oxycodone M30s the blue oxycodone pills

[Mgold55]

How can you tell if these pills bought on the street are laced with fentanyl, I read somewhere you can get "fentanyl" test strips, is this true, if so where can i get them? Thanks

Online pretty cheap. Type in a search engine. And I have heard some needle exchanges do the strips for free
