I know back in the day there were some labs that you could send gear to get it tested and verified. Does any still exist in the US
Palumbo sells a test kit on his site, don't know if it's worth a shit.
Dont think its in USA but you only have to send one cap,tablet or 1ml of oil to get tested. Im pretty sure its called Simex and they give you the exact dose and all compounds in the gear
