I'm 24, and I have only few yrs of non-serious training, and I
don't think I will possibly ever take steroids.
Steroids are like shortcuts, and feeds on humans' laziness. Because
of that, many people over-dosed (i guess) leading to the many
problems.
Even if you don't take steroids and had muscles, they will
become flabby too when you stop exercising. This is not mainly due
to steroids I think.
