I don’t think testosterone is FDA approved for women, but they’re well behind the curve and there are still negative conclusions out there about it that are outdated. But if you watch what is going on in areas where people are more affluent, testosterone for women is definitely a thing. They don’t prescribe high dosages for women like they do for men, but dosages to get you up to the level that you were decades ago.
I have concerns about pellet therapy (because if they get the wrong dosage, you’re stuck in it for three months, and I only go to a doctor and clinic who know exactly what they’re doing, take blood tests and measure for the correct amount. I use cream that you can easily adjust the amount of. Definitely wouldn’t go to a medical spa! It is pathetic that you often can’t even get this from an endocrinologist, they don’t know how to prescribe this for women. Seriously? The information is out there, and they are far behind.
I had to go off my testosterone for a few weeks several years ago because I was trying to figure out what was causing my heart palpitations. Turns out it was caffeine and stress, but wow, what a difference. I am usually very level and not overly emotional, secure, have feelings of well being, happy and confident (undeservedly, no doubt 
). I was anxious, emotions all over the place, no confidence, fearful, what the heck? Is this how women feel as they get older? No thank you!
