From day one bhank has had an HGH and DNP look. While he's lean and muscular he doesn't look like a bodybuilder, no V taper, shallow pecs, shallow lats, despite a low body fat he still has a bloated gut. He looks more like an experimen, Toxic Avenger.
The picture Joswift posted of Krank looks like a bodybuilder. Not just lean but developed musculature. Idk if that pic is from Krank's bodybuilding days or his crossfit days but you can see how the muscles are built up. Krank has the foundation of a bodybuilder. Brain has the foundation of a druge user.
