my friend uses folx and it was good for him to start out with, but now he goes through their medicaid to a federal health clinic and it's ridiculously cheap. i use planned parenthood with my insurance, but i could use my PCP (some prescribe hrt, some don't) or the same clinic my friend uses.
I will also vouch for their responsiveness! It was a pain in the ass to get my bloodwork done in my area as I had to leave town to get to the clinics they worked with for free (otherwise it would be $700 every time for me), and I don’t have a car, but other than that… I liked them.
