Please be careful and please read as much as you can about hormones before you even consider doing them on your own. It is better if you do consult with a doctor and have him/her prescribe them to you. Please be aware of the risks before you take HRT on your own and do lots research. Also just to protect your credit card info use a prepaid credit card. search engines like Bink will either block you from entering a online pharmacy or give you warnings about it.
Most States have low income based health care that will allow you to get HRT as a transgender for as low as $10 so please do a search for those programs first before going to the internet.
