Rules, I'm no roid expert by any means, but back in Bohnstedt's day it was a relatively mild dosage. Decca and anavar if I recall right and a lot of the guys stayed on the program year round.
But there were some pretty wild exceptions and one exception that I am personally familiar with was the good friend who called around the world doing a research project in an attempt to determine what roid program would produce the fastest and greatest results.
He decided to do a personal roid experiment to see just how far he could go without getting real sick.
When he found out what he wanted to know he charted out the "life cycles" of everything he planned on taking which amounted to a series of "peaks" and "valleys" and set it all up so that he never came off a "peak".
His program eventually came to 2,100 mg of orals and injectbles daily for a couple of weeks and then a gradual tapering down.
Sometime during his third month (if I recall correctly) he entered a contest and won his wt class, the overall, the best poser, and the most muscular (could have won the bodypart awards too but I don't recall if they offered them at that event).
He had to take the trophies apart to fit them all in his car.
At that same event, they had an IFBB contest that allowed the amateur winner to enter and he managed to win that one too, but I don't recall who he competed against. Definitely not anyone of the Olympia or Universe caliber but definitely good enough to be pros.
He was definitely unbeatable that night and totally "juiced", and he was the first one to admit it.
That evening he got home and consumed a meal that was apparently too big for his stomach and suffered the consequences. He called to tell me that he felt like his stomach was tearing apart from the inside. His wife got him to the base clinic where they pumped out his stomach one way or another.
The next night his wife was working on base and he called to say that he thought he was going ot die and asked if I would come over in case he passed out. So I packed up my tooth brush and headed out, but before I got to the door he called back and said that it had passed and all was well.
So I unpacked and hit the rack.
I got a call the next morning and he told me that during the night he had another "attack" and felt like he was dieing and his wife was on 24 hour duty on base, so he got up and drove down to the all night grocery store and walked the aisles. He figured that if he passed out or got real sick, someone in the store would find him.
When his wife returned the next morning, they rushed off to the hospital and all that they could determine was that his blood pressure was too damn high.
And it was still high one week later, so he visited a doctor off base who worked with a number of the pros and local athletes and got one shot of "something".
The next day he had another appointment with the on base doc and was surprised that his blood pressure was back to normal.
He attributes that to the "shot" by the off base doc, but never did find out what it was.
After that experiment he cut off his roid program and got back to normal and eventually became a BB coach and one of the brightest lawyers on the east coast.
He is one of those guys that loves to take chances so he never did regret that experiment wild roid experiment.
I no longer have any interest about what the pros take but it would be interesting to see if anyone takes anything over 2,100 mg/day for an extended period of time.
