i use to experience a pain right at the back of them by the muscle in the groin. It was an involuntary muscle spasm caused by anxiety (which was increased by steroids, ephedra, etc.). It was very painful and would last a few seconds to 20 seconds.
Hell yes I've felt it before. I'm thinking it has to do w/ the stimulation of the adrenal system which affects the testis....I took time off b/c of it and pain went away. Sure scared the shit out of me though.
its starting to subside which is nice.. i dont know but i feel like the stacker i took was way overdosed.. i have been taking stackers for almost a week now (Was off for a while before) and each time the effect of each pill was just like the last pill and the pill before that and so on but this morning its like i took a super stacker or something.. like all the ephedra got mixed into one cap...
i am really really feeling the effect.. increase hear rate.. tons of energy .. dry mouth .. pissing non stop .. very focused.. no appetite..
