Ephedrine can be hard on the prostate. Effects seem to be temporary, as in they generally only persist while taking the drug. I sometimes get diminished urine flow and dribbling when taking EC. The symptoms resolve when I stop.
A semi-joking, repeated statement in response to the question of how much EC one should take goes something like: enough just short of your prostate swelling up to the size of a grapefruit. Cute, but not funny. A few guys have reported long-lasting prostate trouble after a bout of heavy EC use. Hard to tell whether E was actually the cause or aggravated an existing condition.
I was hoping you had given up on this rapid fat loss business and had adopted a more moderate, longer-term plan geared toward adding some muscle.
