Honestly, it's not my video. I'm sure this guy is faking how much he was really lifting here. In all of his other public pictures/videos, it's obvious he is not built like anyone that can pull even 365lbs with this kind of form.

475x5 is about a 550 1RM. You guys really see this as legit? He probably weighs about 170-180lbs max. That's an elite level deadlift.. Cmon now. Anyone that's done heavy deads knows how quickly you'd be injured before progressing to this weight with terrible form. But hey the guy has obvious self-esteem issues from his old skinny pictures. I wouldn't be surprised if he's using the juice to boost his ego. If he's on gear, then you could do whatever you wanted with terrible form.
