I think this is one of the more interesting threads I've read here in a long time. Thanks to the original poster.
I think Ross is correct on what will build the most muscle hands down is Tren. IMHO I think Tren is second to none in overall quality gains and by far the best stuff I've ever used. Tren will transform your physique. I LOVE the stuff. I have been fortunate enough not to experience too many sides on Tren, but that's just me I guess. I find Tren-A to produce more sides than Tren-E and I get much better results with Tren-E. Actually the only negative side I ever experience with Tren-E is sweating when I eat a high protein meal but Test does the same to me too. So my vote is for Tren-E.
