the number one reason females should drink their winny is because winny is a AS that's often faked... if your winny isn't winny, but test, drinking it isn't going to do anything to ya... if ya poke and it's test, you're shopping for a jock strap next week...
and besides, as mentioned before, most don't notice a difference since either way AAS must be metabolized by the liver (meaning oral or inject, it works the same)
