Never have in my life. I still don`t understand what the appeal is. A Natural physique, in my opinion, simply looks better and can be achieved at no detriment to your health. I don`t like the "rounded" look that a drugged physique provides.
A Natural physique is more "straight-edged" and "razor-like", not rounded.
With all due respect, if this is a picture of yourself, then I doubt that you are totally natural.
Well you are, if you don't think Winstrol or Anavar are steroids.
Otherwise, you are not natural. Close, but no cigar.
