I've used injection testosterone cypionate previously and now been on compounded cream for five months. On the T-Cyp, I felt more inclined to engage in physical exercise, driven, almost compelled to exercise, get a pump going. On the cream it's like I have to make a mental effort. Blood levels of all measured parameters are approximately equal now to what the T-Cyp levels were. Perhaps subjective perception, mental component but can't figure what, Testosterone is testosterone, I would think. Is this possible? Anyone experience similar effects, what's going on?
