    Why is Progest-E trusted but there is no consensus on a good pregnenolone?

    From what I understand Peat had stopped recommending pregnenolone because of poor reactions he was hearing, and suspected the quality of pregnenolone had declined. But progest-E's progesterone is USP and AFAIK he was still recommending and using progest-E in recent years. Does anyone know where...

    Cells preferentially accumulate Pregnenolone (P5), Progesterone (P4), and DHEA

    A study not directly dealing with disease, though its findings are probably relevant for all diseases. It demonstrates that in addition to the so-called "active transport", which we have been told is the dominant mechanism in steroid absorption and intracellular relevance, there also exists a...

    Pregnenolone (P5) blocks stress-induced anxiety, hypertension and cocaine cravings

    A great new study, and with humans too! As the study aptly demonstrates, the primary driver of cocaine cravings is likely stress and the anxiety it causes. This finding is another corroboration of the findings of the great Rat Park experiment/study on "addiction". In the study below, the...

    Androgen Biosynthesis in the Stomach

    For the last ~6 months I've been experimenting with pregnenolone in different dosages, frequencies, schedule and routes of administration. There are already numerous threads about it's effects (they are very different depending on all those factors), but I want to mention two things that I...

    Pregnenolone/aspirin can block cellular estrogen uptake, PUFA promotes it

    I have posted in the past about the "obscure" estrogen estrone sulfate (E1S) and its role as a biomarker of both onset and progression of breast, colon, prostate, endometrial, and many other cancers. Despite its major role in cancer development, E1S remains known to mainstream medicine as simply...

    Anti-Peat Why do children have so good health if their androgens low?

    After thinking about peating, I wondered: why are children so metabolically ideal that they even overtake elite athletes by this factor, if their androgenic level is very low? Is it strange that everyone on the forum is talking about the rejuvenating effect of androgens, if children are the...

    Pregnenolone (P5) improves recovery from stroke

    One of the few direct studies with P5 in-vivo, though that may be changing as I noticed the rate of articles on P5 has been rising over the last 5-6 years. This study used four (4) administrations of P5, at a HED of just 0.3mg/kg, 1, 6, 12, and 18 hours after the (ischemic) stroke was caused...

    DHEA, pregnenolone oral vs topical conversion
