This stuff was given to me yesterday by a guy who knows I do drugs and I guess had me in mind while he was clearing out some old medicine. I would estimate that I have about 62mL in this bottle. The prescription was filled in May 2007 and the "discard after" date is May 2008. From what I hear, this is the stuff used to make syrup or "sizz-urp". What are your opinions GC? Can this stuff actually go bad and fuck you up or is the discard date just a pharmaceutical precaution?
