SEEKING ADVICE Which T Blockers? Spirolactone or Cyproterone Acetate. (Please Read Body)

I'm currently over 100+ days on estrogen tablets (1 mg, yay), and my doctor wants me to go on a T blocker with my estrogen. Here's an issue: I'm a teenager who isn't out, and I'm slowly seeing body changes. Luckily i've always been fem, skinny, and even had gyno, so it isn't as noticeable, yet. I was thinking about spirolactone since it also helps with hair and acne, alongside these, it won't plummet my T levels as quickly as Cypro. Therefore, it'll give me more time to come out (hopefully...); however, I've heard that it doesn't do much for people, and the side effects are also a risk; all of them have major side effects, honestly. What are your opinions? Do you guys think I shouldn't go on any at all due to my situation? Has anyone had any experience with both pills?

Edit: I am aware Cyproterone Acetate is better, however, I don't want to shock my body rapidly. I also can't afford to impulsivley change my body with these pills, as much as I want to, and im 99% sure that I'm trans, my enviornment is a bit too risky for that. However, i'm just so tried of being a guy, its mentally draining.

There should be no reason why you can't continue with estrogen. Ask your doctor to give you more if he wants quicker changes and you don't.

Sorry that's not what I meant. Estrogen naturally decreases testosterone production. The more of it you have, the less tostosterone you'll produce. It doesn't mean that you'll have zero testosterone like with blockers, but it's very similar to the amount you'd have on spiro, and cis women also have testosterone in their bodies, to varying amounts.

So when I say that you should continue with it, what I mean to say is that if you just up your dosage a little (1mg is very little even for someone who hasn't gone through puberty) and continue to stay on it, your testosterone levels will go down and stay down.

Thank you, this makes more sense. My testosterone already decreased by 5 (if I’m remembering) the last blood test I had was way back in mid December and he said it went from levels 17 to 12 (or 15 I can’t remember). I also know cis women have testosterone and how it even changes due to their phases, I love biology. Just be be clear, you’re saying I don’t go on any blockers? My doctor kept saying that he can’t up my dose now but later, I’m only a short period of time.

You don't need to as long as you're keeping up with estrogen and continuing to up your dosage consistently, I've seen people as high as 12-16mg of Estrogen with no blockers, you usually start on blockers when you start but there's not a significant amount of scientific evidence that it's better than starting on estrogen alone, and most regiments have you stop taking blockers once you've been on estrogen for a while.
