Well, hang in there, weathergirl, I'm sure you'll figure something out. Acne and irritability are signs of too much testosterone. My testosterone prescription says to apply 5 mg per day, but there's no way I'm going to use that much. I barely touch the cream with my finger and apply it to my wrist. It doesn't seem like much, but less is more, so I hear, and it appears to be doing something. I'll know more when I have blood drawn. I highly recommend the book The Savvy Woman's Guide to Testosterone by Elizabeth Vliet, MD, even though it's quite old (2005). She discusses all the pros and cons of all the different hormones and different methods of application. I don't agree with everything she says, though, and just use it as a guideline for questions to discuss with my doctor.
Take care of yourself!
