Here's what we do know from the show 'Wife Swap':
1. The kid's father was a heavy steroid user (from his dad's competition photos looking like an bigger, uglier Mentzer).
2. The kid's father is more into his son's bodybuilding career than Matty Ferrigno appeared to be in Pumping Iron.
3. The kid's parents have completely spoiled and indulged him to the point where he is already an unbearable narcissist.
4. The kid is 100% dedicated to being a pro bodybuilder and has the drive and discipline to do it at any cost.
5. All of the above factors weigh heavily in favor of his being a steroid user.
Access + Poor Influences + Narcissism + Tunnel Vision = User
