Even these females who are fitness models are taking testosterone in low doses
Here is a person who is a Natural, no steroids, Sandow also never did a ridiculous diet, he ate like a human, not stuffing himself, its unhealthy and dangerous to stuff yourself unless you are a high calorie burning athlete. Steroids is the end all, without it those guys would look slightly bigger than Sandow or some even smaller, Steroids can make you or break you in bodybuilding and some guys are huge responders to roids like Kevin Leverone he was a beanpole with horrible genetics growing up but when he took the juice he became a hulk.
“I am myself no believer in a special diet, still less in a rigid one, as necessary while training. The old nonsense on this subject, about raw eggs and underdone meat, seems to be passing away, and more rational views now prevail. I eat whatever I have a taste for, without stinting myself unduly; nor do I restrict myself seriously in what I drink. Commonly, I abjure anything intoxicating, confining myself mostly to beer and light wines. Tea and coffee I never suffer myself to touch. All I impose upon my appetites is that they shall be temperately indulged.” – Eugen Sandow, System of Physical Training
