At first I only took a little bit each day because I wasn't ready to transition yet, but I didn't want testosterone to be changing my body any longer so I can be ready when I want to transition, and you can do that with these. So I took 2 of Calm Companion, 2 of AndroEase, 2 Feminol and 4 Evanesce a day. You can find all of those at the website. When your finally ready to transition completely and start growing breasts all you have to do is bring up the dosage, which for me was 2 of Calm Companion, 2 of AndroEase, 4 Feminol and 6 Evanesce a day. These are a lot cheaper than most other hormones out there. I started doing that just 2 and a half years ago and now I almost have C cups! I have to wear a bra everyday now hehe, which makes me giddy to no end. I have the feminine curves, hips and waist now, and my face is more feminine, it's lovely!
Also the breast size you are going to get is all about genetics. If your mother or sister has large breasts then these will probably give you large breasts, and vise versa if they have small breasts. Check out their forums, they have people saying they have large breasts now because of these hormones.
You can check out their list of ingredients and look up what they ingredients by googling them, or looking them up on wikipedia.org to see they are safe and effective. You can also ask any questions you have about them in the forums they have at myevanesce.com. You can ask Dianna there who is the main distributor there, and you can read about her here: *Link* What she been doing for the TG community is so amazing, and she deserves a big thank you for that.
Here is the page where they list and explain the ingredients in My Evanesce: *Link*
There is also My Evanesce Extra Strength, which is what I've been using since it came out, which I think may have been around a couple months ago, sorry I can't remember the exact time. It is said to be more potent than the regular Evanesce. *Link*
