Started a cycle of test e 250 at 500pw( Isis pharm) every thing was spot on libido was up generally feeling pretty damn good, week 4 and my strenght was up and starting to gain. At around week 3 my nips became a little ore and sensitive so I began adex at .5 eod for a week and dropped it to .25 eod after. Week 5 I went on to jdl test e 250, now usual work out in the gym yesterday every thing was a struggle and I seemed to be down on strength, libido has also dropped. What I'm wondering is the jdl fake or have I killed my estro? Nips aren't sensitive anymore, I've dropped the adex just to see what happens. Any advice would be greatly accepted.
