out of those (and i don't think paraphenalia is an appropriate term,lol) i would prolly never do, well..... i dont' think there's any i wouldn't do. accept maybe insulin.
I would try anything once, but there are some I would only do if they were free and I had nothing else to run, like anadrol. I don't see the point of that shit. Water gains that go away as soon as you come off...what's the point?
