What does a microdose/low dose of HRT look like?

Hello, was wondering if there were any AMABs who are currently on a microdose regimen of estrogen. I'm currently on a full dose as I initially id'd as female but now view myself as enby and want to transition closer to masculine. However I can't deny the huge positive mental impact estrogen has given me and wanted to see what kind of dosage I would be looking at if I chose to microdose, and what kind of effects it would have. Currently I look pretty much like a teenage boy/girl and am also wanting to stop boob growth, right now they're not super visible on loose clothing which is fine but are pretty clearly boobs without. Thanks in advance
