Badr isn't a heavyweight. Police discovered lots of gear in his appartment and fridge. Without the hormones he only weights about 86 kilos (189 lbs)
He can only fight on gear, then his weight goes up about 18 or 20 kg, which is a lot for someone who isn't a bodybuilder...
Without AAS he has no chance in the ring
And he's a criminal, as most men from morocco
All in K-1 were on boatloads of juice (or in Pride and UFC for that matter), Hari height and reach was a big advantage, put him on a heavy stack (from 2007 on mostly) and you have a very dangerous fighter, only Schilt was bigger... Yes, he wasn't a "natural" heavy, mass/strength wise, just like Ruslan Karaev, that's why they always crumbled under heavy punches, they couldn't take much punishment, their tactic was always to overwhelm the opponent, and they both had loads of natural talent...
