This is actually a great important question
Sadly, CBum couldn't answer the danm question .... he said he got injured, he fasted for 80 days etc etc bunch of BS nothing to do with HOW LONG DOES IT TAKE .
Like Bob Paris once said; that's rented muscles, you stop the sauce it all goes away ....
Anyways some 20 years ago I made a similar post here ...
I'll say 3 months or even less than that will deflate an Olympian winning physique
Take Arnold, he won his 6th Olympia on November 8th 1975 (looks like he quit steroids right there)
by first week of February 76 ' there's pictures of him skinny, long haired ... he was in actor mode, and his agent landed him some acting gigs for commercials, so he did some adds to reach mainstream audiences for burgers. cigarettes, soda etc they all wanted him to show his muscular body; however that was rapidly gone, he only flexed his bicep like 17 inches at the time! just 3 months after winning the O at the age of 28!
But that was 50 years ago ...
So, How Quickly Does An Olympia Physique Fall Apart?
WooooSHHHHHHHHHHHH
