From (IMO) most to least likely:
-
I had an orchi way too early and completely starving my body of testosterone with the resulting high SHBG stunted growth (this would explain why my nipples got sore again when I almost detransed)
-
I am simply THAT much of a bodyhon that they exist but are just spread out across my enormous chest
-
I pregdosed myself for an incredible amount of time (nearly 5 years) and that fucked things up
-
I took progesterone too early because I was using it as a blocker and it capped my final size smaller than a flat cis girl
-
I took spiro for a year
-
Genetics (Unlikely, cis and trans women in my family all have breasts)


It’s kinda impossible to tell where you levels are without testing sadly. Also my SHBG being so high was likely a combo of the E dose plus my orchi.
6mg how often? That’s definitely pretty high but might make sense for monotherapy
1wk EEn for monotherapy. I started off with a 5mg starter dose but i feel better with 6 and changed around 2mo. I want to test but the SHBG tests are so fucking expensive. Might do it at the 6mo mark tho!
Yea I’d say its worth doing at least once
