My HRT doctor upped my dosage my estrogen. (Plus I switched to injected estrogen.) She thought my testosterone was too high (below male, but above normal female) and didn't want to up my Spiro any more. She said the with the upped finasteride combined with the increase estrogen, it should reduce the free testosterone in my body.
As far as being wasteful, a 90 day supplewas $24, but the same 90 day supply of is cheaper at $13 at Costco. Simply because the is for MPB (cosmetic) and the is for Prostate (medical).
