At what age did most bodybuilders start using steriods?

[TheMachine06]

Its a difficult question but when did you think most of them started?

[fit2bOld]

I have no clue. Most pro's are in their 30's
I don't think you will ever get any fact on this only speculation.

[lovbyts]

A better question is how many of those who started because they wanted to become body builders, how many made it? I'm guessing about .05%?

[EKFitness]

got a feeling a lot started under 18

[Brewster]

I don't know about body builders but........
Many Athletes start in their first year of college

[Bonaparte]

Most of the competitors I know started around 17 or 18. But none of them went fully pro, and they've largely given up on their dream and work blue collar jobs now.

They use steroids?

[Times Roman]

I think they ALL waited until their mid 20's when their hormonal systems were fully develop

(what did you EXPECT me to say to an 18 year old?)

Don't be naive,

Bodybuilders are all natural.
