I think it's not the roids, but the whey proteins, liquid sups, especially creatine, that we consume so much of that causes the runs, frequent trips to the bathroom, gastorintenstinal distress, gas, and burning and irritable bowels. These long term and constant irritations eventually manifest themselves into those goddamn piece of shit pain in the ass fucking hemmroids that you'll have to watch for the rest of your life.
I blame whey protein for most of it. And mono creatine is the worst thing in the world for your intestines if you ask me.
