The heart thing for Arnold was no biggie? He had to have open heart surgery. What if the problem hadn't showed up, he might be dead now. Also be careful what other stuff you take to body build. Some body builders who took ghb, thinking it was okay cuz it came from GNC and other health food type stores have ended up addicted to it. They have seizures and all sorts of health problems cuz of it. So be careful what you take cuz the FDA doesn't regulate most of it and you could end up seriously damaging your vital organs.
