I usually do about 6 week cycles. My last cycle I used AST Research's 5-Diol 250 and 19-Nor 250. This was by far the best prohormone stack i have ever taken! All I can say is if you want to see "results" from prohormones, the 100mg capsules are pretty much useless unless your stacking it with something else. I've found that taking about 1000mg of prohormones to be very effective for me. I just started a cycle of 19-Nor 3 Andro today so I'll let you all know how it goes in about a month. As far as gains, I usually add some muscle to my body and end up looking more vascular and cut up, not to mention strength increases. There's usually a noticeable difference in my physiqe. The guy I work with thinks I'm on steroids. It's pretty funny. I don't know how much weight I actually put on because my bathroom scale is screwed up.
