How it works Kisspeptin and NPY promote the release of GnRH in the hypothalamus. GnRH stimulates the pituitary to release luteinizing hormone (LH) and follicle-stimulating hormone FSH. LH stimulates the Leydig cells in the testes to produce testosterone (enhance uptake of cholesterol and conversion in pregnenolone, etc.) and FSH stimulates the Sertoli cells to produce … Continue reading All you need to know about LH and the LH to testosterone ratio
Some people hate on eggs due to their high cholesterol and polyunsaturated fatty acid (PUFA) content. Certain individuals think that PUFAs, specifically linoleic acid, are the cause of the obesity epidemic. I agree with the research that seed and nut oil consumption has sky-rocketed in the last 50 years and that it correlates near perfectly … Continue reading Why the PUFA and cholesterol in eggs are not a problem
Would you like to sleep through the night, train hard without bonking, and go multiple hours between meals? The ability to do so depends on glycogen. The body has two main ways of storing energy. Glucose as glycogen and fat in the adipose tissue. Glycogen can rapidly provide energy in the form of glucose to … Continue reading Can’t sleep through the night? Stabilize your glycogen.
Uric acid is under fire lately, with lots of respected PhDs and MDs saying that uric acid is the cause of diabetes, cardiovascular disease, metabolic syndrome, chronic kidney disease, hypertension, gout, etc, etc (R). It’s bad. And the reason why they focus on uric acid, is because they want to demonize sugar and meat. In … Continue reading Uric acid, meat and fructose || The cause of diabetes?
One study in 2018 showed that zinc antagonizes the androgen receptor in vitro in prostate cancer cells. But that does not mean zinc will antagonize the AR in a non-cancerous cell or anywhere else in the body. A more recent 2020 study found that zinc supplementation significantly increased testosterone and androgen receptors in rat prostate … Continue reading Are androgen receptors increased or inhibited by zinc?
Tongkat Ali has been shown to inhibit the aromatase in vitro, but lead to an increase in total estradiol in vivo. According to this study, 600mg Tongkat Ali with 1.45% eurycomanone didn’t lower estrogen, but actually lead to an increase in testosterone. Testosterone increased from 802 to 926ng/dl after just 14 days and estradiol increased … Continue reading Is Tongkat Ali a good aromatase inhibitor?
Tongkat Ali has been shown to increase testosterone in healthy young men, with already high testosterone. According to this study, 600mg of Tongkat Ali (1.45% eurycomanone; 8.5mg total) increased young (average age 24 years) males’ testosterone from 802 to 924ng/dl in just 14 days. Make sure you get a product specifying eurycomamone content, which seems … Continue reading Tongkat Ali for increasing testosterone (get the right extract)
Is meat bad for testosterone and thyroid hormone production? ————- ———— ————- TLDR: Protein doesn’t negatively affect testosterone or thyroid function. The different amino acid profiles of different protein sources can differently affect thyroid hormone-binding proteins, which can modulate the free T3 fraction. Hypothyroid individuals would do better to avoid pork and duck (maybe turkey … Continue reading Optimize protein intake for testosterone, thyroid and muscle growth
If saturated fat is good for testosterone but endotoxin bad, how can saturated fat be good if it enhances the absorption of endotoxin and causes inflammation? TLDR: Saturated fat is positively correlated with testosterone levels, as 40% is often better than 20%, depending on the amount of calories consumed or the amount of adiposity someone … Continue reading Should “inflammatory” testosterone-boosting saturated fat be avoided since it increases endotoxin
TLDR Shilajit at 500mg daily helps to increase total (roughly 100-125ng/dl) and free testosterone (19.14%), improve dopamine and sexual function and enhance exercise performance (or at least act as a potent adaptogen and delay overtraining). SHBG There isn’t any direct research on shilajit and SHBG, but shilajit improves liver function. SHBG is produced in the … Continue reading Shilajit on testosterone, dopamine and sexual function
