Major pharmacies are a problem. I was fortunate to find a in-person doctor who prescribes it and a compounding pharmacy that dispenses it. The prescription is for a pill that is the correct dose for my body weight. I pay under $5 per pill.
You may want to work backwards. Find the pharmacy and then the doctor. There are definitely online options to get a prescription, but you will then be able to tell them where to send it.
Now I need to find a blacksmith to get my next pair of shoes.
One unexpected benefit for me appears to be a reduction in eye floaters, which I think increased after a bad cold this year. Maybe it was parasites swimming by. Not all gone, but much improved. I take it once a week, no side effects.
Plot twist: one of the hecklers was Fetterman.
