Did crisler say how he treated those people for their cortisol issues? I would love to optimize my levels, but just not open to using any of the synthetic medications to do so. Is there such thing as bio-identical cortisol that someone could take?Ok. I hear you. Crisler did an interview years ago that said it made a huge difference in many of his patients lives even if they were within normal range. I’ll probably look into it because just about every afternoon I crash hard around 4:30.
