HUGE factor!!!!
Test is lame without a proper diet, and i can say that for most. Its all about what you keep after cycle and without a proper diet u dont keep much. I love prop and will continue to use it. I do ED injections too and have no issues. The first couple weeks it was painful but you get used to it and becomes almost pain free.
The only thing i did like about the enanthate and cyp was the great water retention which helped in the gym....

maybe im the only one who likes water retention...
