This has been posted before (long time ago, I'd completely forgot about it). It's a shame these guys are being fed bullshit (although to be honest they don't exactly seem like the sharpest knives in the drawer to begin with . . . ). If you watch closely when they're talking about that "software" telling them their upper genetic limits, you'll see an excel spreadsheet in there that has "FFMI" on it. Reminded me of this site naturalphysiques.com/tools.php?itemid=28
No idea if it was the same algorithm they were using, but I know that this one tells me I'm beyond what they define as "pretty much an upper limit for someone who does not use steroids", and I don't even train for aesthetics or size, I train for olympic weightlifting. Not to mention I've never used any supplement other than whey protein and a multivitamin.
Although it was nice to hear that bald kid talk about finding happiness at the end. At least one of those guys did some kind of growing.
