It made it burn when I urinated. I was taking an NYC stack though that also contained asperin.
Also it made orgasms extremely intense, at times extremely painful even. lol. It almost felt like someone was stabbing me down there afterwords. I know too much info, but its true. lol
I'm thinking Norephedrine or Yohimbe affected my prostate somehow. That's the only explanation I have for these two side effects. ECA never did this to me.
