T4 has a very long half-life. A patient shouldn't panic if they miss a day of T4. Conversely, T3 has a much shorter half-life and therefore you do need to stay on top of your T3 when you give it.

In this special episode of The Drive, Peter provides a comprehensive overview of the various endocrine systems: the thyroid system, the adrenal system, and the sex hormone system (for both men and women). He walks through the basic biology and the feedback cycles that regulate the production of these hormones and discusses the various options for the treatment of hormone deficiencies. In addition, Peter delves into hormone replacement therapy (HRT), providing nuanced insights into its appropriate usage and the clinical approach he adopts when working with patients.

Peter supplements these explanations with whiteboard illustrations. For a more complete understanding, we highly recommend watching these videos over just listening. The videos can be found on our YouTube channel or on the show notes page.
