Arimidex , how often?

[Marcus G]

7(days in a week) divide 2(because your doing it every 2nd day) that equals 3.5 is the number of days in the week 3.5 times 0.5 equals 1.75.

Is this the simplest form?

OK so what days would he take it on then

OK so what days would he take it on then

So if he pins on monday he will take it. Then wednsday then friday then sunday. Thats four days. But the next week he will take it on tuesday then thursday then saturday thats 3 days etc etc so its avreged at 3.5 times in a 7 day week.
No need to complicate it. Take it one day then skip the next repeat till pct
