John Grimek tried testosterone with Dr Zeigler in mid fifies according to Fair, but reported it did nothing at all for him. That suggests he never tried such things before. Later he tried Dianabol and still no effect. Grimek must have had plenty of male hormone and using more did nothing at all for him.
The vet stuff gave Melvin gynocomastia. Of course, Melvin swears he has had that condition since adolescence.
the usual story, much like Larry Scott, who when asked how much dbol he did used to say "until I get nosebleeds", it was common knowledge he used/abused dbol, look at at the nice round bloated moon face on Scott in the 60's. Many years later, when it became a big media negative story, he started to claim to have done 5mg a day the one time (way after his olympia days

), and it did nothing for him...
Grimek, Reeves and the other york boys all did test and dbol in the 30's.
