Do a search for "free clinics/USA" and see what, if anything you come up with. O, the Mazzoni Clinic is no longer free. They charge $10/visit for those with no income and then go up for people with income.
There's Tom Wadell in SF and there may well be others. Compounding pharmacies, another google search can provide you with low-cost and pure T and/or E that they make themselves. The pharmaceutical companies run basically the same process and come through at about 3x the price (less shipping for the compounders, which is fairly cheap) and their batches are much larger. Seems to be an excess profit motive working there. Another huge surprise! No?
Wal-mart has low prescription prices on some items, but the list changes every month and the numbers of pills you can get from them is very limited. But, when you can get them there, their charge tends to be low. Just a roulette-wheel about what costs how much when.
For other meds you may be able to get them from some sort of internet pharmacy.
The endo visits are a bit more pricey, as you might expect. Back when I last saw one, some few years ago now, his initial visit was in excess of $300. Regular visits were about $175 twice a year.
Transition is not noted for being inexpensive in the USA. Then again, nothing seems to be except poverty. We give that away daily for free.
