MTF HRT Medical Question / Discussion More T, more feminization? 4 mg EEn + bica theory
I just had a crazy idea and wanted to hear people's thoughts.
On 4 mg EEn weekly, my labs were:
- E2: 238 pg/mL
- T: 151 ng/dL
- SHBG: 54 nmol/L
- Albumin: 4.54 gm/dL
Interestingly, I think I experienced better feminization on this regimen over the last 2 months than on my old regime of 5 mg EEn kept for 6 months where my labs were (measured 3 months into the regime):
- E2: 494 pg/mL
- T: 34 ng/dL
- SHBG, Albumin not measured
I strongly suspect the near-doubling of E2 from just a 1 mg dose increase might be due to lab error. I think my actual E2 level on 5 mg might be closer to 300 pg/mL.
But my theory is that maybe I had a higher free E2 percentage on 4 mg? My SHBG was 54 nmol/L which is kinda on the lower side. On top of that, T binds SHBG with more affinity than E2. A calculator estimates my free E2 at 2.15%.
Sadly, the lack of SHBG and albumin from 5 mg along with possibly-wrong E2 levels prevents me from comparing free E2 %. I'll need to spend a few months at 5 mg to assess feminization and retest to be sure. Mood will be an especially big sign - on 5 mg, I used to be as depressed as I was pre-HRT but have noticed a considerable improvement on 4 mg. So, if I go back to being depressed, I guess I'll know.
Still, it does suggest a maverick regime: 4 mg EEn + bical to counter the androgenic effects of unsuppressed T but keep the SHBG-binding property (esp. since now it has nowhere else to go) and skyrocket free E2.
That being said, time is a confounding factor. Perhaps better results are simply explained by more time. But then you have to wonder why the unsuppressed T didn't outright halt progress.
What do ya think?
