I am currently on a EQ -100mg eod - Anavar 40mg a day (20-am-20-pm) cycle - supposed to be light, but when it really started to kick in -my nuts shrank. At that time they began to hurt, kinda felt like I had just been racked for a couple of days. Then it stopped. I guess everyone is different - but that is what happened to me. The only thing that I would be worried about if I were you Is- Why is there only one nut that hurts... Weird- but If the pain does not go away after several days - then I would discontinue my cycle - you do not want to screw with your manhood.
