I bought some BD 5mg winny last year and I have to say it rocks. Very strong. The only reason I bought them is that I'd read a test on them that showed them dosed 9-10mg vs 5mg.
ordinarily I would say that is a bad thing, I want to know what the dose is on what I'm taking but it was pretty cheap so I bought it anyway. When I used it I tool 10mg first thing in am and then 15mg preworkout. If I use it again, I would reduce the dose to 15mg preworkout (which could be as much as 30 if they are overdosed) I got very quick results though, strength, hardness and some tightness/joint pain within a few days.
