Not sure how I'd be classified

Six months ago I started prescription testosterone creme as treatment for low testosterone. Now my levels are in the low-normal range for a woman my age (39), and I feel like a completely different person.
I haven't noticed increased muscle size, but my strength and endurance are vastly improved. I now have a libido (nothing out of control - but used to be in the negative range though). Best of all, I no longer fall asleep at inappropriate times (was almost diagnosed with narcolepsy but the test creme amazingly cured all symptoms).
Women's bodies need some testosterone for many functions other than muscle building, including bone building and brain function, so that's why I'm taking it. If I wanted to build more muscle, then I'd be using something stronger/more anabolic. The creme I use is so mild it hasn't even given me a pimple.
So, am I natural or not? I don't know and don't really care, and since I don't compete, it's really a non-issue. I don't think supplementing to get my test levels in the low-normal range gives me any kind of unfair advantange though. On that same token, I don't feel that someone with low thyroid taking T3 has any advantage over me in the dieting department. Besides, I'd rather not need the stuff - it's a pain to fill prescriptions and get periodic blood tests.
