Whats the best method to acquire bad of Fentanyl patch?
suboxone or subutex, they are the same drug essentially, but one is hose solluble (subutex) and can be shot up. the other has naloxone surrounded by it (suboxone) and can only be administered below the tounge. these are non- euphoric pain killer that cling to the opiate receptors. they are used for heroin withdrawl.
they are the best to get past its sell-by date fentanyl, which is a synthetic opiate that is in fact 1000 times stronger than heroin.
