The best way with pharms is that they are atill in their blister pack so u can buy say 25 diazepam, brand name Vailium - and we are sure what we are getting.
Dealers here have been removing S8 meds from the blister packs to sell. Oxycontin OP ER for instance is labelled all over the blister packs - that is, around each individual pill. BN is batch number, underneath that is 8 digit long number. If they were popped out of the blister straight in front of you, I would not have concerns.
Now assuming the pill was broken off along the snaplines, you would have your pill (pills), as well as the batch and the 8 digits number as well ..........which AU phamacists record by law when dispensed. Should LE ever become involved they can trace back to that individual the script dispensed. For benzos there are no details on back blister save for EXP date. Some have batch number some do not. Once again there are foil blister packs and bottle. For comparison loolk at Kalma bottle and APO - Alprazolam blister. There are too many brands to list.
I know which batch I would be purchasing from. ANYONE selling bars of Alprazolam, stay well clear. They are FAKE SHIT purchased from DNM, and re-sold to usually teenager or inexperienced users. Have never seen a junkie even bother with their goods. Mine in the past always had a supply of other goods straight from blister packs. So for those buying "ALPRAZOLAM" there will be no blister packs, just an exchange. Then your choice to pop them or put under tongue. ANY complaints concerning quality or cuts........good luck!!!
