Congenital defect, nothing to do with roids.
Then explain this smart guy.
The autopsy gave the cause of death as dystrophic multiple-organ-failure.[3] Some of the specific autopsy findings:[3]
An extremely muscular physique, with an almost complete absence of subcutaneous fat
Affecting the liver were numerous table-tennis-ball-sized tumors; half the liver consisted simply of a crumbly mass, similar to polystyrene (Styrofoam)
Diminutive testes
Cardiac hypertrophy (Hoffman's heart weighed 636g; a normal man's heart usually weighs 300–350g)
Hoffman's electrolytes were also completely out of balance, and his potassium levels were extremely high. Traces of about twenty different drugs were found, along with acute toxicity (perhaps caused by a stimulant).
Oh wait, this was from Andreas Munzer's autopsy. Fuckkkkkk
