SuppVersity - Nutrition and Exercise Science for Everyone

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...

Do you risk all of these benefits of T that have been illustrated artistically by artofmanliness.com if you take melatonin supplements? I have written about the multitude of beneficial health effects which range from improvements in sleep quality over its beneficial effects on glucose and lipid metabolism to its potential cancer protective effects more than once; and after the publication of each of these articles I have received messages of some of you who were concerned that taking melatonin could ruin their testosterone levels. Since interesting studies are a bit rare, these days I am going to use this article to address this issue once and for all: There is no conclusive evidence that melatonin could put you at risk of developing full blown hypogonadism (=clinically low T). Want to learn more about melatonin ? The SuppVersity is the place to be. Melatonin as potent as Letrozole Melatonin for Bone & Tooth Health M. Sleep Aid W/ Anti-Alzheimer's Effect M...

We are what we eat! Acknowledged, but does this also go for your hormones and different in protein intakes? Let's have another look at the contemporarily available research to figure that out. In recent study in the International Journal of Sport Nutrition and Exercise Metabolism a group of researchers from the Faculty of Physical Education and Recreation at the University of Alberta reports: "Supplementing a typical daily food intake consisting of 0.8 g of protein ·kg-1·d-1 with a whey protein isolate (an additional 0.8 or 1.6 g·kg-1·d-1) [...] had no effect on glucose, insulin, testosterone, cortisol, or growth hormone following the final mea l" (Forbes. 2013). I know, anything else would have been a real shocker. What it wouldn't be, though, is a total surprise. If you dig through the available literature you can easily find data that would support the scientists' assumption that doing an experiment "to investigate the effects of a controlle...

If the Aliens have seen these Bugarash apocalypse pilgrims, they have probably turned tail and fled ;-) I guess the SuppVersity figure of the week was a date "12/21/2012", I mean this is a once in a life-time event! Or do you really believe there will be another chance for mankind to be snatched from the jaws of extinction? Ok, enough of the sarcasm, the world is still there and the SuppVersity is still operating, so let's get to the not so short On Short Notice items for today. If there had been more room in the headline I would probably have labeled it "Endocrine Special" and I guess once you have gone through the posts, you will agree that this would certainly have made sense. Traditional treatment of osteopenia with Epimedium brevicornum works, 'cause it's a potent aromatase promoter (Yang. 2012) -- When a group of researchers from the Chengdu Institute of Biology, Chinese Academy of Sciences and the School of Chinese Pharmacy, Chengd...

Image 1: Arnold does the "double bicep" + vacuums. If you want to look like a bodybuilder, muscle alone is not enough. First, I want to thank Jahed, Pablo, RF, Angimal, Garrett and Rudolf for their patience. After all, it has been two weeks now since you have submitted your (meta-)goals, which were all more related to building muscle and increasing performance, then to losing body fat, which was the topic the last installment of the Intermittent Thoughts dealt with. Yet although, at first sight, both topics have little (to nothing) to do with each other, there are are at least three important factors by which a reduction in body fat is very well related to increased muscularity and skeletal muscle hypertrophy . Let's get back to the "Peter Griffin" type of chubby person from the last installment , for a few seconds. Imagine "Peter" has packed on, say 10lbs of lean muscle and now stands in front of you, does the "double bicep" and vacuu...
