Is it really safe to use a hormonal pill?  

My friend is gay. Yesterday, we had a conversation about him planning to take a hormonal pill. I wouldn't agree with him because I'm not sure if its safe or not. Now he is taking gluta pills to whiten his skin and all that. But he really wanted to look like a girl, have his own chest and all that. I told him it's not necessary to look like a woman especially nowadays, there are more gays that stays that way. I don't know, I'm not really against surgeries or anything to change your natural body. But, I am concern on my friend's health. Is is really safe?
