My wife used NPP. We first did 50mg 2x week and it was too high for her. We dropped it down to 25mg/2x per week, and that was a perfect dose. She was also using 10mg anavar everyday. My wife responds very well to low doses, so it sounds like you're likely in the same boat. She experience no side effects, but she was hornier than normal. So that was a good thing.
No acne, oily skin, etc..
These are the only things I think a female is ok to use.. Primo, NPP, Anavar, Clen, HGH, and Test Prop(very low doses, helps with menopause/hot flashes)...
