You can change a female to a male or hermaphrodite, but males cannot be changed.
I'd recommend NOT using female hormones on anything you smoke.
Although you might like those 36 C's you sprout.
More fun in the shower.
Yeah I've never done the estrogen thing.
But I've heard many people talk about it.
Hormones are dangerous to play around with if your dont' know what your doing. You can easily **** up your body by changing the hormone production in your body so I don't actually recommend that you use any kind of chemicals including hormones on anything you plan to injest.
