    Androgens (T, DHT) highly protective against the flu

    A gem of a study that throws a wrench in one of medicine's core dogmas - i.e. androgens have detrimental effects on the immune system and males have evolved to live with a trade-off between high androgen levels (and as such high fertility) and higher risk of severe viral episodes that can be...

    The skin as a steroidogenic organ

    Here's a collection of studies on the skin as a steroidogenic organ mainly to show that hormones like pregnenolone have a different metabolization topically, compared to orally. "The cutaneous steroidogenic system can also have systemic effects, which are emphasized by significant skin...

    Trenbolone Improves Cardiometabolic Risk Factors and Myocardial Tolerance to Ischemia-Reperfusion in Male Rats With Testosterone-Deficient Metabolic S

    https://academic.oup.com/endo/article/157/1/368/2251856 perhaps this shows how non-aromatizable steroids can be more beneficial than testosterone in certain subjects. What do you think @haidut? is trenbolone peaty? /s

    Topical DHT therapy promotes hair growth

    Despite mentioning it in another post on testosterone (T) treatment for hair loss, I thought that this study deserves its own post, just because its findings are so contradictory to the perennial dogma of "androgenic alopecia" - i.e. that androgens, and especially DHT, cause the male-pattern...

    Testosterone therapy (TRT) reverses hair loss (in women)

    The evidence undermining the fake/corrupt hypothesis of "androgenic alopecia" keeps accumulating. I really wish the study below was conducted in men instead of women, since its findings would have probably finally put an end to the debate as to whether androgens promote or inhibit hair growth...

    DHT restores anabolism / vitality / sexuality even in 90+ y.o. males

    A great study, a true blast from the (better) past, when androgenic steroids and especially DHT were not considered the devil reincarnate, but were commonly used for all types of ailments, including the broad physiological and psychological symptoms of aging such as sarcopenia (muscle loss)...

    Androgens (e.g. DHT) curative even for treatment-resistant breast cancer

    As many of my readers know, back in the "good ol' days" (when medicine was slightly less evil and berserk) breast cancer in women was treated with androgens, and the results were so impressive that a synthetic DHT-derivative known as Drostanolone / Masteron (2α-Methyl-DHT) was approved by the...

    Heart attack survivors have high stress (cortisol/adrenaline) hypersensitivity, low androgens

    A very interesting study that highlights yet again the connection between chronic stress and ill systemic health, especially cardiovascular disease (CVD). The study demonstrates that people who had experienced a heart attack have dramatically higher higher cortisol and adrenaline/noradrenaline...

    HCG And Proviron - Are They Safe?

    Hello, I need to inquire about the safety of two separate drugs/steroids that I'm inclined to take. Both of these would be to optimize hormonal issues engendered by 5-AR blocking via finasteride. I'm positive that I need to push my system artificially with a drug in order to heal my hormones...

    Androgens Boost, Estrogen Inhibits, Anti-aging Gene Klotho

    This post has two main messages, based on the studies below. Namely, androgens (and especially DHT) potently increase the expression of the anti-aging gene Klotho while estrogens strikingly decrease its expression. Moreover, the more potent the androgen, in terms of androgen receptor (AR)...

    Irritable Bowel Syndrome (IBS) Caused By Histamine And Serotonin

    I did not expect to see this statement in a mainstream science news outlet, but here it is below. I am starting to see a change in attitude towards serotonin but mainstream medicine is careful about its game. Somehow, the message about serotonin has now split into two separate, nonsensical ones...

    Aromatase Inhibitor (AI) + DHT Combo May Reverse Kidney Disease (CKD)

    A truly great study for a number of reasons. First, it cites extensive evidence that male patients with diabetes (both types) have low androgens and high estrogen (estradiol). The association between this endocrine abnormality and the severity of diabetes is apparently quite strong, yet it is...

    Topical DHEA Has Potent Anti-aging Effects On Human Skin

    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...

    Long Chins, Big Ears, Long/narrow Faces = GH, Estrogen?

    I notice some feature mix ups and combinations. Guys with stronger jaws (not sure about women though) tend to have larger ears, but there are guys with big ears and longer chins (downward protruding more than forward) that lack the same jaw types and facial broadness. Since the effects of GH...

    DHT Is Negatively Associated With Death From Prostate Cancer

    Just a quick study that, despite being epidemiological, raises serious questions about the validity of the "androgen-driven" hypothesis of prostate cancer. If the assumption is that DHT is the primary driver of prostate cancer it is hard to come up with any plausible explanation of how the...

    Estrogen, Not Androgens, May Be The Cause Of Baldness

    A quick post about a study calling into question yet another dogma in medicine - i.e. that the "evil" androgens (especially DHT) are the causes of men losing their hair and getting prostate cancer. So, the "solution" modern medicine proposes is "chemical castration" with drugs like finasteride...

    Estrogen And Cortisol, Not Androgens, Suppress Immunity

    There is a very famous theory in reproductive biology still considered the dominant one in its field. Namely, males have to accept a trade-off between androgen levels and immunity. It is known as the immunocompetence handicap hypothesis (ICHH). Higher androgen levels, the theory goes, allow the...

    Drop In Androgen Levels Causes Parkinson Disease (PD), DHT Reverses It

    Yet another study demonstrating that many of the so-called chronic, degenerative and above all "mysterious" conditions often have quite a simple cause and, potentially, treatment. There is no need for mutated genes or complex interactions of genes with environment that nobody can decipher...

    Testosterone Does NOT Impair Empathy In Men

    I am sure most readers are quite familiar with the cliche that testosterone (T) is what drives stereotypical "boy behavior" - aggressiveness, carelessness, impulsive behavior, risk taking, cheating, and of course the militaristic attitude characterized by lack of (or reduced) empathy. As I...
