Why the Same Hormone Works Differently for Every Woman

Why does one woman feel incredible on hormone replacement therapy while another gains weight, feels anxious, or sees no improvement at all?

The answer isn't simply the hormone—it's how your body processes it.

In this episode, Dr. Brendan McCarthy explains why the route of hormone delivery (oral, topical, injectable, or pellets) dramatically changes how hormones behave in the body. He also breaks down the role of liver metabolism, sex hormone-binding globulin (SHBG), body fat, inflammation, insulin resistance, and lab timing—and why these factors matter when creating an individualized hormone treatment plan.
