    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...

    Intranasal pregnenolone

    Anyone else tried this? Just a small pinch gives me such profound and immediate effects like no other supplement. Not just limited to brain/mood but also increased proprioception, body coordination, strength and endurance. @Makrosky @shine @Arnold Grape a few years ago you wrote "I've been...

    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

    What is the topical equivalent of 50mg of DHEA? How many mg topically would I have to apply to my scrotum to get the same benefits of a a sustained release 25-50mg? Same question for Pregnenolone. How much topical pregnenolone is equivalent to 100mg of oral pregnenolone?

    Is 39 ng/dL too low for a pregnenolone blood test result? 34 year old male

    I decided to test pregnenolone to get a good sense before I hop back on to supplementing it. The result seems very low? The range from Labcorp is <151. Checking online I've seen the lower range being 33 ng/DL. The other tests I got, in case they help understand my pregnenolone result were...

    Negative effects from dosing too much Androsterone+Pansterone?

    I usually use 2-3 drops androsterone+4-5 drops pansterone once a day, or slightly less of each 2x a day, and the effects over the course of several months were quite noticeable. Improved energy, motivation, self-discipline, fat loss and muscle gain, decreased depressive symptoms. I wanted to...

    One of the best TRT alternatives (natural potent stack)

    Going on TRT can be a challenging decision. How long are you going to be on? How are you going to get off? Do you want to get off? What about fertility, risks, success rate, etc? I'm not trying to say TRT shouldn't be an option, but want to give an alternative. Fixing hypogonadism naturally is...
