I found the combination of micronized bio-identical progesterone, oral Estradiol, and injectable Estradiol Valerate to be the most effective for my development and mental health. My dosing reflected my cyclic needs, with the appropriate peaks of E and P at intervals reflecting a natural menstrual cycle.
I intend to return to this method as soon as I can get an insurance override for injectables again.
As it is, I still dose with oral E and vaginal P suppositories to match my cyclic needs.
Once I have the injectables, I am considering simulating pregnancy levels for 9 months, in order to hopefully stimulate more breast growth.
Good luck with your experiments, I am always surprised by how few MTFs make any pro-active efforts to maximize their HRT experiences, especially considering the very wide range of opinions held by various prescribers. I have never been one to just accept a declaration as untestable truth. Without giving feedback to our prescribers, we are likely to be subject to a very generalized treatment plan that may, or may not, actually be in our best interests. The seemingly 'default' approach is to prescribe as little as possible, with as little variability as possible. For me, that was never going to work out well, as I do cycle. Today is the first day of my new cycle, and I feel palpably better, though I am still bloaty, and my ankles are swollen, but for the most part, my back, leg, and abdominal aches are relenting. If I still had my uterus, I would have started bleeding today. If you have been reading my posts during the last weeks, you may have noticed that the bottom fell out for me emotionally about a week ago, and despair and depressive thoughts had darkened my mood on several occasions. This is the norm. In a week or so, you will likely see me tending toward more sexual thinking, lol, as my Venus week begins and I move toward my peak in two weeks. For about the next 5-6 days afterward, my mind will be happy, and very sensitive, but in a very sexualized way. I also have a very randy time at the end of my cycle, like I did earlier today, lol, where penetration is very important to me. All these are standard features for any woman that cycles. This was apparent to my trauma therapist even before I noticed it, since she and I met several times a week during most of my early transition. I like it. As a woman, it is part of what I am as well as who I am, regardless of my intersex status..
My endo also has bio-male MTFs that exhibit limited cyclic experiences, and he adjusts their HRT accordingly...
Just my experiences, and anecdotal feedback, always consult your doctor before making any changes to your prescription routines...
