Is it true that USP progesterone use causes high cortisol levels?
by Jo Grant
I have used both Tri-est and USP progesterone for about 4 years now. I have had a hysterectomy as well, within about 2 years. My cortisol level is high and I have heart palpitations all night causing chronic insomnia. I read that USP progesterone can cause rise in cortisol levels. Would like very much to know if this is true or not.
