just curious

At what age could you start using steroids if your goal is bodybuilding???

First thing first.
Do mean bodybuilding in the sense of getting huge and ripped or fitness style build?
Secondly, do you have the genes?
Give a training history and maybe a few pics. The gurus here will quickly tell you yes or no.
And AAS' s shouldn't even be thought of before ~25 (more than enough info on this site as to why. Use the search function and read.)

Been training for 3 years

I know that fitness I can do without any gear , its bodybuilding that in my passion but also don't want to mess my self up just to compeet , would do fitness for the next 4 years and start gear at 25 and more on to bodybuilding

If you plan to compete in bodybuilding and do well then you'll have to commit to using quite a lot of steroids. There is no way around it really. I wouldn't recommend steroids to anyone under ±23 unless they have the genetics to win at national level. There are always risks involved with AAS so you need to decide what you're willing to do to reach your goal.

You can put on good weight by eating and training natty correctly while in your early 20's. Admittedly you won't get massive but you can set up your base from where to work from once you start the AAS's.

What training have you been doing?

Lastly, are you and "thenewguy" acquainted or are you "hijacking" the thread?
