of course a female grows more,if a male takes 20mg of test its under the amount a normal male produces,he wont grow much!but if a woman takes 20mg of test,its about 5 times more than her normal levels so she has to grow more than men do.The women cannot reach as high as males though with the roids,like Mike80 said,the bone structure is too small,and other stuff play a role in this too!
