I don't see what your problem is with Shelby, Block.
So what is his "prep" consists of many exotic drugs including DNP.
THEY ALL DO IT.
Palumbo, Hany, Chad, Troponin or whatever.
they all use drugs and diet with or without carbs, not that it matters much in the first place.
Dude doesn't have the prettiest physique but he did get insanely shredded and he does make drastic changes to his physique months after months.
I'd say he must be a good prep guy
