Yes, it's a pretty well known fact now that most of these transformations (particularly men) are steroid fueled. You simply can't gain 22 pounds of lean mass without some chemical help. NOT POSSIBLE.
I've seen people gain 22lbs in 8 weeks on a dirty bulk that ends up resulting in 8-10lbs of muscle and the rest fat. However, to gain that much lean mass and be that lean at the same time ....just not naturally possible, even on steroids that's a tall task.
