A couple dudes that used to train at gym that I belonged to said that they asked Francois (after a seminar) what steroids were his favorites....
His answer: "Anadrol and Deca"
Besides being freaky huge, he was so dense and rock hard. IDK if that's due to drugs, genes, or some combination of drugs, genes, and heavy training, but he looked like he was carved from steel... while most other guys lacked that extreme density and hardness and were starting to get that puffy, bloated look back then.
Regardless, he inspired me to do lots of heavy pulls, squats, etc - the "hard stuff" that most won't do that at least makes us mere mortals bigger and stronger than average gymrats.
