I do not believe he took that much not even in a week. He was just boasting. Whatever happens at 2-3 grams won't be diff from 7-10.
probably took somewhere around 3 gram mark, but as maxrep said, the guy was always into shock and awe, center of attention
The whole sleeping under boardwalk thing, training 7 hrs, eating dumpster bound loads of Mcds, etc, probably all happened at certain times, and not for long or often, but makes a good story.
Like when platz first arrived, he slept in his car, ate tuna cans in his car, his most prized possesion was a can opener..showered at the gym. It happenened for like a week, but they make it sound like he lived like that leading up to turninhg pro...
Either way, he does seem to be kind of guy that took things to extreme and was a fun guy. Also, an astute businessman
