It doesn't seem complicated so much as pointless. But that's just me.
And a quick search shows that companies provide samples of their protein powder to third party agencies to do testing, but I didn't find mention of any government agency regulating the products, unlike, say, a piece of meat. I wouldn't be surprised if I were wrong, mind you. I didn't look too hard.
Anyway, as I often say, opinions are like assholes--everybody has one. If he's healthy, who am I to say he should do differently. It's not for me, though.
