i can honestly say that this is some of the best underground gear i have ever tried. im only into week 3 of my 1500mg test eth 600 deca 50mg/ed d-bol cycle and i can honestly say the pumps are better then any other spectro, genmed or I.P. cycles. iv done these dosages before but its never hit me this hard and this fast... so to sum up i suppose im saying if you can get your hands on this stuff do it!!!
