OC is like synthetic heroin. Im not a doctor or a pharmacist, but a great observer. And iv'e seen some of my friends from high school that use to be foot ball players go right down the drain with this shit.
They weren't just doing 5mg a day, they'd "smoke" 20-40mg's using tin foil for the running pad an a straw to inhale the smoke. When they weren't doing this shit they were 6' 1" 195, now they're about 180ish and wierd looking. Loose skin everywhere where muscle use to be, and a proaged face and mental illness and obvious change to their psychological state.
I wouldn't worry about 5mg ED. just make sure you dont exceed that.
