That's cool and all, but when you consider the fact that most HRT docs don't even bother prescribing AI's, I find it rather silly.
He might've said that because it's easier for people who have no brain not to forget to take a pill the same day they're getting an injection...
Also, HRT is usually once a week or once every two weeks (or even longer), so I don't see how taking an AI once a week or once every two weeks makes sense.
If your testosterone has a half-life of 1-2 weeks (depending on what you're using), and arimidex has a half-life of 3 days, how does that make any sense?
