In my 4th week of a 10 wk run, Duroteston-500mg/wk and QV 300 Deca -600mg/wk. One of the 20 Duro amps turned to gel. I ran some hot water over it and most of the gel went back into solution but not all. I shook the amp but could still see some gel so I used another. I know the stuff good so whats going on. I've seen the same thing with vials of Cip but they always go into solution under hot H20.
