Hi Penny,
Congrats on your results! You're lucky. Yeah, it seems like these herbs are very effective on you. You're so slim! You have a great body to start this from and it seems like that helps a lot to get/notice results. Plus, it must be so nice to have a supportive partner.
You and I have very similar goals, so I'm curious about your progress, how you'll continue, if other herbs might factor into what you take and what effect they might have on you.
I'm also nonbinary and want curves and other bodily changes like soft skin with minimal breast growth, all while maintaining erections and performance. Some breast growth for myself to enjoy is great, but I want to keep presenting male and have them small and unnoticeable, if at all. I also want the mental/emotional changes people talk about. You said you don't have a specific end in mind, but have you experienced those nonphysical changes? Apparently, some people start up this herbal HRT for some small physical changes and get hooked on the way it makes them feel, going much farther than they originally intended. So it's worth considering.
We're using the same herbs but very different bases to start with. I'm tall, large, and heavy, mostly muscular, but with flab and a small belly. Thinning head hair, but hairy elsewhere with a thick beard. Late 20's. Single. Seems like I have a lot of T or DHT to overcome so progress is slow, especially since I'm still experimenting with which herbs I like and figuring out how far I want to go.
Pretty much everyone here recommends the Ainterol brand for PM and I got a rec from another user for Hawaii Pharm WP, so I use both of those and they seem like good quality, if you're looking for good brands. Like others here recommended, I tried Ainterol's PM breast cream on my hips, used a full tube by massaging one or two beads into my glutes daily. I think it was effective? Can't say for sure because I had just started and was not at all consistent with what I was taking, but my ass definitely felt different for a time. I stopped that because it wasn't cost-effective and I wanted to nail down the other herbs I liked.
Other staples for me are maca and green tea. Maca's supposedly a superfood that's just great for your health and hormones in general, increases libido and energy (I can vouch for the libido and helps with erectile dysfunction), and, anecdotally, a lot of people say it's great for growing your hips and butt with exercise. Green tea reduces DHT and raises estradiol, according to Lotus. Her posts are super helpful for understanding, if you haven't seen them.

So for you, the licorice root extract was your anti-androgen and you decided to not use it anymore? For the the health reasons only, or did you just not need an AA? It seems like you might not since you're not going for huge breasts and your herbs are already effective. I used to use Saw Palmetto for my AA since it also has some effect reducing estrogen, so some transwomen on actual HRT on other sites were apparently using to maintain erections. SP made me dizzy and easily fatigued so I stopped with it. I think I did feel more effect from my estrogenic herbs on it, but this might be placebo, was licorice the same for you? I'm considering adding it but yeah, the health complications with blood pressure seem dangerous. Do you even want an AA now?
Don't feel like you have to reply to everything, I'm a long-winded typer. Just wanted to put that all out there in case it was helpful or if you could help me learn more. Good luck with your progress!
