    Androgens (DHT, T) Treat Prostate Cancer, Especially When Combined With Vitamin D

    I recently posted a study showing that vitamin D inhibits the deactivation of androgens, which results in a build up of strong androgens like DHT. https://raypeatforum.com/community/threads/vitamin-d-inhibits-the-deactivation-of-androgens.12411/ That study conclude that this effect of vitamin D...

    Vitamin D Inhibits The Deactivation Of Androgens

    Vitamin D is one of the most versatile substances in Peat world. It is actually a steroid and not a true vitamin, and as a steroid it is expected to have effects on other steroids. Its role in opposing estrogen, together with the other fat-soluble vitamins, is well-known. Now, this study shows...

    Androgen Treatment Highly Effective For Breast Cancer

    The first study (animal) looked at various approaches and found that removal of the pituitary caused the complete disappearance of breast cancer in ALL of the studied animals. The administration of DHT caused almost complete regression in 82% (14 out of 17) of the animals. The HED for DHT was...

    11-keto DHT - Adrenosterone Derivative For Lab/R&D Use

    As promised, I am releasing a steroid that may be of interest to some people on the forum. It is a variation of the well-known steroid DHT that Peat has written about and I have also posted quite a few studies on. The steroid belongs to the group of the so-called keto-steroids and AFAIK this is...

    DHT Lowers Serotonin Synthesis, May Treat (testicular) Cancer

    This is a great study for a number of reasons. 1. First, it suggests that DHT is not the evil substances for male reproductive organs. This includes prostate cancer, for which DHT to this day is cite as the main culprit. 2. Second, the study establishes the key role serotonin plays in the...

    DHT Is Estrogen "receptor" Antagonist

    I have posted studies on DHT inhibiting aromatase and increaseing estrogen conjugation and excretion by the liver. However, this study shows that DHT is actually capable of direct anti-estrogen activity by binding to and antagonizing the estrogen "receptor" similarly to progesterone and vitamin...

    DHT Reduces Glucocorticoid Effects

    I mentioned this on one of the Danny Roddy shows, but wanted to post this study here as many people have been asking me for references over email. In addition to reducing glucocorticoid effects, DHT is also an estrogen "receptor" antagonist as I posted in another thread. DHT Is Estrogen...

    Lower Androgens And/or Increase In Pituitary Hormones Linked To Increased Mortality In Men

    So much for T and DHT being bad for older men. More specifically, lower androgen levels and higher pituitary hormone levels were linked to higher cancer and CVD mortality. Temporal changes in sex hormones linked to increased mortality in older men "...Increased risk for all-cause mortality was...

    Niacinamide Is Androgenic And Increases Dht Effects/signaling

    I just posted a study showing that inhibition of SIRT1 is anti-estrogenic, and SIRT1 inhibitors like niacinamide have similar effects to the estrogen receptor antagonist fulvestrant. Niacinamide Is Anti-estrogenic | Ray Peat Forum This study shows that, again through inhibition of SIRT1...
