I use HIMS or whatever and its fine. I forget how much i paid exactly but it's like $0.60/day for the yearly supply. I bet they're all the same, pretty much
It used to be a minor hassle to have to order it from India and all that but now you can just sign up, send some pictures of your hairline, and some NP licensed in your state will write an Rx and you'll get the meds in a few days.
The only minor complaint is that they send you emails nonstop for their other services .. boner pills, antidepressants, etc
