Yet another studies demonstrating the “controversial” link between stress and a condition doctors insist has nothing to do with stress or hormones in general. This time the culprit is CRF/CRH, which is the initial step in the “stress” cascade and is now known to be implicated in conditions such as multiple sclerosis (MS), Alzheimer, depression … Read more
As many of my readers know, the first step in steroid synthesis is the so-called “side-chain cleavage”, which converts cholesterol into pregnenolone (P5). That step is known as the rate-limiting step in the steroid cascade, and its function depends on the redox status and ATP levels. In other words, the rate-limiting step of steroid synthesis … Read more
I often get emails in regards to possible interventions with anti-aging effects on skin. The study I usually quote is an old one (circa 1967) that did extensive tests on 200+ people with age range of 57-88 years residing in a retirement home, and demonstrated that topical testosterone (1%) cream had the most potent anti-aging … Read more
Take this study with a grain of salt simply because the only link to it is from a scientific conference, which means the study is not yet published in peer-reviewed journals. Yet, the results it reports are quite interesting. Namely, a single 100mg pregnenolone (P5) dose accelerated recovery from intensive physical exertion in the form … Read more
This is an old case study, reporting dramatic results from treatment with high doses pregnenolone (acetate ester) for an intractable bacterial infection that was rapidly spreading and proved resistant to all other therapies. The dose of pregnenolone (acetate) used was high – 100mg twice daily for a 6 year old child. That would correspond to … Read more
About a month ago, I made a post in regards to aspirin becoming a new treatment for osteoporosis. Several months ago, I made another post about an in-vitro study demonstrating powerful anabolic effects of pregnenolone (P5) on bones. Apparently, the protective effects of P5 on bone health are known in certain circles and there have … Read more
About 2 years ago I posted about a study that suggested pregnenolone may relieve low-back pain in humans. At the time, a bigger human clinical trial was planned and the results of that trial were just released. Pregnenolone, slowly titrated to reach doses of 500mg/day, was found to be safe and effective for low-back pain … Read more
Yet another aspect of health that turns out to be directly controlled by quality/speed of metabolism. I made a few posts in the past demonstrating that progesterone and pregnenolone activate a calcium channel (CatSper) specific to progesterone, which greatly increases sperm motility. https://www.nature.com/articles/nature09767 https://www.sciencedaily.com/releases/2016/03/160317150803.htmhttps://www.sciencedaily.com/releases/2016/03/160317150803.htm However, I suspected that this is not the whole story behind … Read more
I often get emails from bodybuilders, athletes and others who have used or currently use steroids and want to either protect themselves while using those steroids or want to recover after long-term usage. It is well-known that most performance enhancing steroids, including plain testosterone (T) or DHT, suppress gonadal function through a negative feedback mechanism … Read more
It looks like the recent FDA approval of allopregnanolone (ALLO) for postpartum depression may open the floodgates to ton of new research with this steroid, as well as with its reliable precursors such as pregnenolone and progesterone. I posted several studies in the past demonstrating that pregnenolone, progesterone and ALLO are all endotoxin antagonists and … Read more
