There were some that did stuff like this year round.
I have an older friend that is retired from powerlifting now, still throws in highland games, but he used to train with two of the best lifters of that era. He was drug free but his training partners were juiced to the gills.
He told me they used to dose orals by the handful, and that they would take so much their blood pressure would go up enough they would turn totally purple during sets, then go sit in a corner puking for about 15 minutes and be ready to go again.
Crazy shit like that.
Even now there are guys taking 100mg+ dbol per day at the top levels in powerlifting.
There is actually a guy I was told about, who has some significant lifting achievements (but I cannot list them, because I cannot identify him) who cruises on
400mg week Eq
250mg week test E
30mg dbol preworkout
Then getting ready for a meet he goes up to
1250mg Test E per week
750mg Tren per week
100mg Dbol ED
And when I told this to my older lifting friend his reply was "wow, the doses have went DOWN since I retired"
