Been on MTF HRT for 39 months (currently 5 mg EEn/week subq, 200 mg/day rectal Progesterone, CPA 12.5 mg and dutasteride 0.5 mg/every 3 days).  E2 431 pg/mL, T 19 ng/dL, DHT < 5 ng/dL, Prolactin 6.8 ng/mL, Progesterone 3.1 ng/mL.

Originally on E pills, and had really mediocre growth (no breast buds until 12 months!), but since I switched to injections, breasts have gotten noticeably larger, nipples enlarged, areolas still appear male-ish.  Got usual other things--no unwanted erections, no ejaculations, smooth skin, body hair lightened and thinned, some genital atrophy, still have male-type orgasms (using Magic Wand).

I'm 69, so figured age is a factor.  I also have diabetes type 2 and take Metformin (1000 mg twice daily).  I take CoQ10 for cholesterol.

Have just started domperidone (10 mg 3 times daily) just to see if that will build up breast tissue (have no desire for leaking breasts).

Not sure if any of the herbs I see mentioned on the site would assist with breast growth, but had wondered specifically about Selenium.

Any suggestions on beneficial supplements?

Thanks, much!
