estrogens and anti-androgens
Starting on hormones is not a decision to be made lightly. Besides the physical changes, there are psychological and emotional changes as well. And hormones can make you sterile! If you're married, or in a relationship, this alone may make you stop and think. If you don't let your partner know you're taking hormones she will soon notice the physical effects (i.e. breasts) and may cause a strain on your relationship. Telling your spouse, or partner, after the fact that you've started hormones is a recipe for disaster (unless you're positive he or she will be accepting). For more see transition and marriage.
On the other hand, hormones can make one feel right for the first time in one's life. Finally giving them the body and psychology of the person they've always been inside. You can usually take hormones for six months, or less, without any permanent effects (although breasts will not go completely away, they will deflate so as not to be noticeable).
If you decide to take female hormones be aware that they can have negative side-effects in some people and it may take some experimentation to find out which hormones and dosages work best. Don't exceed the suggested dosages (see below). Cigarette smoking increases the risk of certain health problems while on hormone replacement therapy (HRT).
Some sources report that estrogen can deplete vitamins B6, C and calcium. Leg cramps can be a sign of a calcium deficiency (women need 1500mg calcium daily) or you may need to back off on your spiro. For more see Ask Tara.
Hormones without a prescription: If you want to try mail-order hormones I suggest doing a google search to find sources, then doing some research on the sources you found before ordering.
I cannot provide hormones personally.
