We are always told that to avoid becoming lethargic on cycle a test base is key. That leads me to believe that lethargy is directly linked to test levels. My question is .. is it still possible to become lethargic while on test? I'm on the last weeks running test at 900 / week and the last 10 days or so I can barely get off my butt and workouts have greatly suffered. I'm thinking about just jumping off now - cycle went a lot longer than I had originally planned anyway. It's also possible I'm fighting off a bug or something too. Could running gear for too long essentially "burn out" the body and I've just had enough and need a break?
