This is true to form... he thinks 1 hour of his time as a personal trainer is worth $500.

Hell, most ivy-league lawyers don't even get $500/hr, let alone some meathead trainer. To put it in perspective, based on a 40-hour week that would be over $1M a year. So, it's not surprising that he's pimping some powders that should go for $20-$25 for $70.
The sad thing is his knowledge and theories are sound. And while I can't begrudge anyone for wanting to make money, being blatantly over-the-top greedy about it is not a way to enhance one's reputation.
