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

Written by | published on

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...

Plasticized - Put Up or Shut Up: How Toxic is Our Daily Load of Bisphenol A and What are the Main Routes of Exposure?

Written by | published on

"BPA free" labels may help to sell products. With more and more of the replacements being identified as just as, sometimes more hazardous than the original, they are, however, by no means as safe as the average consumer is made to believe by the industry. I have been keepin' you up-to-date on the latest research on bisphenol A and often not less toxic alternatives in the Facebook news  (if you didn't do that already, like facebook.com/SuppVersity to see them in your newsfeed). The publication of a new review by scientists from the West Pomeranian University of Technology in Szczecin in Poland reminded me that it may be worth addressing this ubiquitous hormonal disrupter in a detailed article again. As Tomza-Marciniak et al. point out as early as in the first sentence of the abstract to their review (which had been published ahead of print in June and was now officially published in the  Journal of Applied Toxicology ), "bisphenol A (BPA) is characterized ...

Eccentric Training Keeps You Gainin' and T & GH Up When, in Weeks 5-10, Traditional Training Stops Yielding Results

Written by | published on

Extra gains, testosterone, and GH in one scientific paper?  That will catch every gymrats interest, right? I know, the name SuppVersity  implies that gains were all, or at least to a significant degree about supplements. In fact, though, they are about busting your ass out in the gym and eating like a freak. And with respect to the former, a new study from the  University of Jyväskylä  in Finland suggests that there is a deeper truth to the former part of this often-heard claim: busting your a** in form of eccentric training, i.e. using the maximal weight you can lift on the concentric and a supra-maximal weight on the eccentric phase of a more will  indeed produce significantly greater increases in maximal voluntary contraction torque (MVC) and (almost) significant increases in muscle gains. Are you trying to optimize your training for gains ? Find inspiration in these articles: What's the Latest on Failure? 36% Extra-Gains W/ Rest-Pause Pyramid-...

Take Control of Your Cortisol Levels - Use These 5x Stress-Modulating Diet, Lifestyle & Supplementation Rules Wisely

Written by | published on

Always remember: You want to control cortisol, not eradicate it if you want to melt away your belly fat , beat your personal bests and feel just great ! As a SuppVersity  reader, you belong to the chosen few who know that cortisol is not the villain as which it is stigmatized in the fitness industry (obviously to sell supplements | learn more ). Rather than being "bad" or "good", cortisol, a glucocorticoid, i.e. a hormone that keeps your blood glucose stable, and potent anti-inflammatory agent, is more vital than any "vitamin" - in spite of not having the magic "vita" in its name. Whether the effects of this vital adrenal hormone are going to be "bad" or "good" for you, depends mostly on whether it rises and falls according to its natural 24-h rhythm or is chronically low (often labeled adrenal insufficiency) or chronically high. If you want to mess with your cortisol rhythm overtraining is exactly what you "ne...
