This is me with 28 years old natural and training since my 20 years with concret weights in my fathers garage:

Should we stay natural until achieve maximum potencial or stars taking steroids first day we enter gym and grow much faster ?

Hard question.

I personally chose the first path.

I trained naturally for many years until I could no longer go further.

In this time I have learned to train, to follow a diet, and I have studied what aas are.
