The main topic is DIY HRT, specifically, how to make it at home with equipment you can buy on a modest budget.
Notably, the guy giving the talk made 100 years worth of estradiol for $400, and most of the cost was the glass bottles (each of which is a 1 year supply.)
Obviously this is not the end-all of DIY HRT instruction, but really a starting point. But he makes a compelling case that doing this isn't nearly as hard as it might seem.
