You are incorrect. I researched DIY HRT for a trans friend of mine. It turns out that in most countries estrogen is so cheap to manufacture, that it is cheaper to manufacture estrogen than it is to replace it with a low-cost alternative.

It's a pure commodity.

I recall when my wife was moved to the generic the out of pocket cost was like $8, which was under the copay. The pharmacist said that the placebo pill that is there for the last days of the cycle was more expensive than the actual drug!
