Mike Mentzer never drank his own urine. That rumor originated with Dan Duchaine and has been debunked over and over. Mike addressed this in his last known interview with Muscle Magazine. He laughed and said, "How would anyone know if I drank my own urine?" Then unequivocally denied doing it. Doc's also used to prescribe amphetamines all the time for various conditions back then - which is how he took it. Really not much different that Adderall, Concerta, or Vyvance, which are all heavily prescribed today. More rumors that Mike acted erratic and crazy have never been substantiated and are bullshit.
A lot of regurgitated nonsense spread by the bro's, LOL. What's new? Mike was one of the pioneers in the Golden Era. Back before the internet, forums, and youtube. Back when you actually had to read a book. Mike was studying to be a physician at one point (psychiatrist) and took pre med classes and read medical books constantly while he was competing early on. He experimented. Tried new things. Talked a lot about making mistakes, especially during prep. Though he followed Jones' work, he never had a coach or someone who told him what to do. That's one of things I appreciate a lot about that era.
Most people look back and shit on him and his work but really have no idea what the fuck they're talking about, as evidenced by some of the dumbass comments on this thread. Now everybody has a coach. "Hey, I'm a dumb fuck, teach me to train, eat, do gear, cycle, and prep." Lol, all kidding aside I know a lot of people make money as coaches on here. But if you do, just give due respect to the greats who came before you (whoever you are) and actually thought for themselves. Mike was a beast and beat Robby and other greats a long the way.
Lesson for the day: stop spreading things you know nothing about =)
