5mg to start 10mg if u want to bump it up is the norm from what I read on the elite womens forum here. My fiance is going to try a 5mg 10 wk run. Remember tho, most effects are reversible but sometimes they aren't. Make sure she knows all the risks and has her diet and wrkout in order or else it will just be a waste.
Oh, there are like 5 Threads on this in the womens forum here if that helps u out.
