Well, I'm kind of torn on the matter. I've only seen one study which showed adverse effects to HDL with aromasin; the study also showed adverse effects with letro, but none with anastrozole(I'll dig it up in a second). I've never used aromasin, so testing myself hasn't been an option at this point. I suppose a safe bet would be to run the maintenance dose of nolva, as the SERM isn't going hinder or hurt anything, but from everything I've read, it's effects to cholesterol are minor, if at all. Rather new in comparison to letro and anastrozole though. It's a med I've paid less attention to as it's not widely used in comparison to the other AI's
What I am really interested in, is the effects aromasin has on gonadotrophin concentrations for it's use in PCT. I have yet to find a study on it.
