Just my opinion on high dose AI to curb blood serum levels of e2:
As exemestane targets the aromatase enzyme -and not estrogen itself, starting with a dose of 50mg is, IMHO, plain stupid. The high blood serum levels are a result of accumulated e2, because the HL of e2 is around 36hrs (citation needed). 50mg would definitely shut all aromatase down (without directly influencing blood e2 levels right away). AI's have a HL to up to 50hrs (citation needed), meaning, about 4-6 days after repeated administration of 50mg there will be a crash.
Just my 2 cents.
