10%(+) Reduction in Testosterone After Glucose and Whey Protein Shakes - Is the Classic #BB Shake Anti-Anabolic?

Written by | published on
Image
We're talking about a cross-over study in adolescent subjects and acute changes but that's neither the only nor the most relevant reason you don't have to be afraid of the bodybuilding staple, now. In fact, a closer look at the data seems to suggest that we're talking about a 'protein-anabolic decrease in testosterone'... sounds odd? Well, here's how it may relate to your #androgenReceptors (AR) and eventually your gainz, irrespective of your age, by the way. I have previously addressed the possible ill effects of very high protein intakes on your testosterone levels - in particular, when those intakes are combined with a caloric deficit and, accordingly, reduced intakes of glucose and fat (re-read "True or False - High or Low Protein Intakes Have Profound Influence on Testosterone, SHBG, Estrogen, Cortisol & Co?" | here )... Now, a new study in Clinical Endocrinology  ( Schwartz 2019 ) shows that testosterone ⇆ protein/carbohydrate inter...

Shilajit: Ayurvedic Testosterone Booster that Works in Men, not Rats: ~20% Increase in Free T + Higher Total T & DHEA

Written by | published on
Image
"Get leaner, more muscular and hornier than ever before" - That's probably the promise on the T-booster someone will release after reading this SuppVersity article and sourcing an inferior Shilajit extract on Alibaba. No, I hadn't heard of Purified Shilajit (PS), either, before I read about it in a very recent study in the peer-reviewed scientific journal Andrologia (Pandit. 2015). Actually, the study was first published in online (ahead or print), in late 2015. It took several months for it to be finally available in print and to appear on my "study radar", though. Shilajit is traditionally used in Ayurveda, an indigenous system of Indian medicine, as a remedy for several diseases, particularly chronic diseases. It is a pale-brown to blackish-brown exudate that oozes from sedimentary rocks worldwide, largely in the Himalayas. The natives describe it as pahar-ki-pasina (sweat of mountains), paharki-khoon (mountain blood), shilaras (rock juice), asphalt...

SARM-ing Up Your Gains - Steroid-Like Lean Mass Gains W/Out(?) Shut-Down and Other "Roid-Like" Side Effects

Written by | published on
Image
SARMs may build muscle, but they don't have significant effect on body fat and thus the visibility of the muscles. Scientists from the  Institute of Cardiovascular Research and Sports Medicine at the internationally well-known German "anti-doping university", i.e. the German Sport University Cologne, have recently published an interesting paper in which they compared (to my knowledge for the first time) how metandienone aka dianabol , estradienedione and the selective androgen  receptor modulator (SARM) S-1  affect the body composition, hormone levels and selected health parameters of ... yeah, of course, of rodents . Before you are now telling me once more that "rodents are no little men", let me remind you of the fact that other SARMs, like LGD-4033 have recently been tested in humans at the Boston Medical Center (Basaria. 2013). Learn more about powerful muscle builders at the SuppVersity Tri- or Multi-Set Training for Body Recomp.? Alternatin...

Size Does Matter! Mucuna Counters Estrogenic Assaults & Doubles Testosterone. High Hair Cortisol, CVD & Diabetes. Catabolic Laziness. Health & Obesity = Incompatible

Written by | published on

While it may be debatable, whether and in which contexts size really matters, 20% of the women in a Dutch study state that they length of the best part of their partner was "important" (Franken.. 2002) While the debate whether or not "size matters" is probably never going to end, researchers from the Universidad Autónoma del Estado de Mexico have now found that your male offspring could "fall short" if they are exposed to phthalates during pregnancy. For their study, the scientists had collected urine samples of 174 mothers-to-be and analyzed them for phthalate residues. Bustamante-Montes et al. did then correlate the phthalate content of the urine of those mothers who gave birth to male newborns (N=73) to their sons' best parts and found that "prenatal exposure to mono-2-ethylhexyl phthalate exposure was associated with a reduced distance from the anus to anterior base of the penis (-0.2 mm/µg), reduced penile width (-0.04 mm/µg) and a reduce...

Tongkat Ali - Malaysian Viagra W/ Anti-Belly Effect: More Than 30% Reduced Omental Fat Pad Size + Corresponding Increases in Testosterone W/ Human Equiv. of 4g+/Day

Written by | published on
Image
It's efficacy in situations like this has more scientific back-up than any of the muscle building of fat burning promises some Tongkat Ali supps come with. By now, most of you should have read the article on the testosterone "boozing" effects of alcohol and realized that the post workout Margarita probably comes off second best, when we compare it to whey and may - at least until we don't know otherwise - actually be pathological (=the result of a disturbance of the normal hormone metabolism in the liver). That being said, we better go back the "tried(!) and proven(?)" stuff. I mean a herb that goes by the name "Long Jack" does already sound way more promising than a "Blood Mary" doesn't it? "Long Jack? ;Malaysian viagra? Ok, I am in!" As the popular name already implies, the root of Eurycoma longifolia Jack , an evergreen plant that belongs to the family Simaroubaceae has a long (all puns intended) tradition in ...

Age-Dependent 100-300% Increase in Testosterone With 50mg of DHEA the Night Before HIIT Training. But is it Still Side Effect Free & Ergogenic When Taken Chronically?

Written by | published on
Image
Don't be fooled. DHEA won't allow you to train forever day in and day out the study at hand does yet add to previous results which already suggested that it could have its merits whenever intensity and workloads are high ( learn more ) I don't know if you have noticed, but as of late, there has been a definitive testosterone deficiency as far as the topics of the daily SuppVersity news are concerned. With today's article on the use of 50 mg of dehydroepiandrosterone aka DHEA "pre-workout" this will change dramatically (read all previous articles on DHEA). Why? Well, the protocol the researchers from the Taipei Physical Education College , the China Medical University , the Asia University and their overseas colleague from the University of Texas at Austin describe in their recently published paper will yield age-dependent increases in free testosterone ranging from +100%, for the twens, to +300% for the men in their prime of their lives (~49 years). ...

Overtraining Research: New Insights into Athlete Triad. Plus: Depression, Palpitations, Urination, Injuries and Weight & Performance Plateaus, the Many Faces of Overtraining

Written by | published on

Chronic overtraining is one of the main contributers to the occurrence of often likewise chronic injuries, which persist even, when you finally realized that your own ambition is about to ruin your health. It's the last day of the SuppVersity Exercise Science Week with a topic of which you actually have read as an aside, or "read up on" note in the previous installments, already: Overtraining and the infamous athlete's triad (read the whole SuppVersity Special here ). Since I know that especially the male SuppVersity readers tend to believe they were bullet, or rather overtraining proof by nature, I decided to add a more general follow up to the results of a tightly controlled rodent experiment from the Graduate School of Sport Sciences at the Waseda University and the National Institute of Health and Nutrition University in Japan (Yanaka. 2012), which provide insights into the etiology of the (female) athlete triad phenomenon. A follow up with a potpourrie of...
