@OrpingtonClose In one of the Generative Energy podcasts, Ray speaks favorably of taking certain aromatase inhibitors, which are estrogen blockers. Progesterone is, in a sense, an estrogen blocker. So is aspirin. The same goes for mushrooms, DHT, and vitamin E. Substances that block cortisol are also recommended by Ray by name, such as aspirin again, emodin (in cascara,) pregnenolone, progesterone, DHEA, and sugar.
Ray does advise against certain estrogen and cortisol blockers. He says that letrozole and anastrozole (aromatase inhibitors) can be estrogenic in some tissues. Ketoconazole, a cortisol-lowering drug, causes severe androgen deficiency.
