If I'm not mistaken the spiro just blocks testosterone to let the estradiol work right?
Not exactly. It also reduces testosterone and can even slightly increase estradiol (and progesterone) levels, but, it seems, not to a significant degree. The important thing to remember...it reduces AND blocks androgens, most notably testosterone and the more potent androgen, dihydrotestosterone (DHT). It also apparently seems to reduce conversion of T to DHT.
QuoteBecause sometimes if there is too much estrogen the body will combat it by making more testosterone.
Incorrect. More E= less T. E does NOT, ever, convert to T but the opposite is true. E also appears to exert anti-androgenic effects within the body, like downregulating androgen receptors, increasing aromatase activity (increased conversion of T to E) and reducing conversion of T to DHT by inhibiting alpha reductase activity.
The idea that the body "combats" too much estrogen with increased T has absolutely no scientific basis and is nonsense.
QuotePlus my doctor prescribed me both in half the normal dose but twice a day to spread it out. I think that should help too right?
Spiro doesn't last long in the body, hence the usual recommendation to take it twice daily plus the fact that Spiro taken all at once can have stronger diuretic effects which can be annoying (having to pee a lot) and can impact electrolytes too strongly.

It is possible to transition on estrogen as I did, but it's not as effective.
I disagree. Estrogen alone can sufficiently suppress/inhibit T and be enough for effective feminization. This has been observed and confirmed, time and time again, by several transwomen who end up with T levels under 20 ng/dl, sometimes, even under 10 ng/dl. It is true that orally, high doses may be required, hence slightly increasing risk of clotting (although disputable) but if taken non-orally, even high doses do not appear to influence clotting to any significant degree, based on studies and what we observe in pregnant women.
QuoteI don't think estrogen only is going to make much difference at first without the Spiro. It sure didn't with me.
It may not have with you because you weren't taking a high enough dose which might have been justified were you taking non bio-identical estrogens which affect clotting to a greater degree.
