I think you’re low enough that I would agree with your thought process. But I’d dose even lower, down to 6.25mg. Plus it’s easier to dose that way with 25mg pills, you know?
I’ll say this: you have done your homework. Seriously. You researched the meds you’re taking, you got blood work, you thought about it scientifically, and then you asked for a second opinion. That’s top notch harm reduction, my friend.
FTR I felt much, much worse with e2 below 20 than I do now at 38. If it was a choice between higher vs lower I’d take higher every single time. You need a healthy amount of e2 for muscle growth anyway.
