Why do some people take their arimidex or letro every other day rather than every day?

[lilcrodyshe]

I know they have a 48 hour half life, but most studies using them for delaying gp closure use the typical every day dosing.Do people do this so they don’t crush their e2? And does eod dosing not cause a spike in e2?

Its about the halflife

same reason reta is injected only once per week
