    Another "paradox" - glucocorticoids cause inflammation, insulin blocks it

    As many of my readers know, I am not a fan of the ubiquitous usage of both bioidentical and synthetic glucocorticoids (GC) in medicine. Once used only in the most severe cases, some form of GC therapy awaits virtually all patients in a hospital (regardless of condition), and doctors are now...

    Progesterone, bromocriptine may treat autism

    A great new study, which, while genomic in character, inadvertently points the finger directly at estrogen and/or serotonin as causes of autism. After all progesterone's main role in the human organism is as an estrogen (and cortisol!) antagonist, while bromocriptine is one of the oldest...

    11b-HSD1 inhibitors don't lower cortisol levels? increased ACTH response

    a lot of people try to lower cortisol this way. But these studies with a 11b-hsd1 inhibitor given to humans shows plasma cortisol levels stay the same regardless and ACTH levels rise. (ACTH rises in response to the lower conversion of cortisone -> cortisol from the enzyme inhibition, so with...

    Niacinamide increases ATP/NAD, lower glucose/cortisol in humans

    A great new study demonstrating for the first time in a human experiment what hundreds of animal studies had suggested in the past. Namely, that niacinamide can serve as a reliable precursor to NAD+ and by raising the NAD/NADH ratio results in improved glucose metabolism and higher ATP levels...

    "Endurance" exercise ages the vascular system of males by more than a decade

    A very interesting study, though I don't really agree with its findings that while "endurance" (in this case running) exercise damages male vascular system it is beneficial for the female one. The majority of intervention studies that looked at both sexes, across all age groups found that...

    Confusion about T use

    In this recent talk Georgi is endorsing very high dose Testosterone use (100 mg a day), saying (according to the study) even 50 mg per day wasn't good enough. I'm very confused now, since I saw him recommend a physiological dose of about 5 mg per day. I use a few milligrams of T transscrotally...

    How high to go on Emodin

    Hi all, I was just wondering if there are any down sides in taking maybe 1g of Emodin a day to force cortisol down. Any side effects or possible issues coming off Emodin? If so, what should be my max dose a day? Thanks!

    How much do you pee per day?

    Serious question. Urine output is a good indicator for cortisol levels. It can be used to gauge the state of metabolism as well. I just took a 24 hour sample to Labcorp. The amount this time was 2.1L. I have struggled with large urine daily outputs for years. Frequent urination is really...

    Stress (cortisol) makes even altruistic people selfish

    A great new study, which may explain a good deal of the general perception and several studies from the last decade claiming that societies in Western countries are becoming more selfish, combative/polarized, and even psychopathic. The more shocking finding of the study was that cortisol was...

    Fasting / stress decimate gonadal steroidogenesis, with no effect on blood cortisol

    A very interesting and very "controversial" (read: inconvenient truth) study, since it shows beyond reasonable doubt that even brief (4 days) fasting is a form of severe stress, at least when it comes to endocrine health. The study may also provide answers to various endocrine "mysteries"...

    DHT as anti-inflammatory as cortisol, but without the side effects

Despite mainstream medicine doing everything it can to conceal the...

    Can lower blood cortisol make you excrete more through the urine?

    I've been taking Lisuride and Gonadin for three weeks with the idea of lowering Cortisol levels. I did the 24 urine test again, and my results were higher than the last time. My result this time was 59 ug/24 hours, versus 50 the last time. The top of the lab range is 62. I think that after 50...

    Is TSH supposed to be higher or lower during pregnancy?

    I have heard according to Peat that tsh should be less than 1. Tsh was 2.3 at 13 weeks pregnant and was 1.8 while not pregnant.
