Actually, it IS possible to test hormones

..but very few doctors do it. Find an "anti-aging" doctor in the nearest big city; it's a simple blood test. But most dr.s are ignorant of this and will give you a song and dance about how they can't.
Regarding saw palmetto...it is usually recommended for men, apparently altering the way testosterone is used by the body...could help, worth a try. But I have to say that i have an unusally high amount of testosterone for a woman; probably the reason for my own acne. However, something else must be involved as not all men who have high test also have acne. The test must magnify something else, probably bacteria (and yeast- not just women have that!). So I found horopito extract helped very much.
