androgens are not responsible for muscle building process. Its the testosterone levels that are responsible.. which women dont have much of to have bulky muscles.
The only way women can have 'bulky' muscles is if they use steroids to get their t-levels up which will allow them to have muscles.
ps: i can bet u on anything you want that a woman whose lifting weights without the help of steroids can NEVER have the physique like the pictures u have uploaded. Madonna's picture is very much fake and you wont look like her if u start strength training. Do u honestly think this is the result of strength training?
Please don't test me on my science of the human body. testosterone IS AN ANDROGEN! It's the most famous androgen. Some women have more, other women have less. In females it is secreted by the ovaries, and the adrenal glands (the zona reticlularis). In males it is secreted by testis in larger amounts and the adrenal glands (zona reticularis). Yes, men secerete a lot more then women, but women still secrete some testorterone.
You do not need steroids to get bulky muscle. maybe they don't get as bulky as men, but they DO get bulkier with strength training. I think slender arms look nicer and flat abs- that is why I work on my abs. I honeslty don't want calves sticking out, manly biceps, or anything close to it.
