A common Q I get is “Should I get my T levels checked Will?” When should you get your level checked? When you’re feeling tired, or lack libido or extra sore from workouts? After age 40? My answer may surprise you….
Many know Red meat has a reputation for being superior for building muscle, and has for thousands of years, but is it true? I attempt to cover that issue in this vid!

Very limited data suggest that meat consumption by older people may promote skeletal muscle hypertrophy in response to resistance training (RT).
The objective of this study was to assess whether the consumption of an omnivorous (meat-containing) diet would influence RT-induced changes in whole-body composition and skeletal muscle size in older men compared with a lactoovovegetarian (LOV) (meat-free) diet.
Nineteen men aged 51-69 y participated in the study. During a 12-wk period of RT, 9 men consumed their habitual omnivorous diets, which provided approximately 50% of total dietary protein from meat sources (beef, poultry, pork, and fish) (mixed-diet group). Another 10 men were counseled to self-select an LOV diet (LOV-diet group).
Maximal strength of the upper- and lower-body muscle groups that were exercised during RT increased by 10-38% (P < 0.001), independent of diet. The RT-induced changes in whole-body composition and skeletal muscle size differed significantly between the mixed- and LOV-diet groups (time-by-group interactions, P < 0. 05). With RT, whole-body density, fat-free mass, and whole-body muscle mass increased in the mixed diet group but decreased in the LOV- diet group. Type II muscle fiber area of the vastus lateralis muscle increased with RT for all men combined (P < 0.01), and the increase tended to be greater in the mixed-diet group (16.2 +/- 4.4 %) than in the LOV diet group (7.3 +/- 5.1%). Type I fiber area was unchanged with RT in both diet groups.
Consumption of a meat-containing diet contributed to greater gains in fat-free mass and skeletal muscle mass with RT in older men than did an LOV diet.
“High” Protein intakes and Cancer, is there a connection? A recent study claims it found a link between “high” protein diets and cancer rates and compares the risk to smoking! Is it true? Learn the FACTS in this video!
Yet another potential benefit of creatine may be improving the effects of SSRIs. There’s many potential health benefits of creatine – for both brain and body – people are unaware of and can read up on via an article I wrote in Life Extension Magazine HERE and here on BrinkZone from vids, articles, free report.
Now, it’s possible, it only works on women and or, only works with this particular SSRI and or only works with MDD. However, knowing that creatine improves brain metabolism in general and has other neuro-protective effects (see recent article linked for more information on that), it’s very unlikely it’s limited to women and or this particular SSRI in my opinion, but one should keep those possible limitation i mind until data shows otherwise. Good science dictates I make sure you’re at least aware of that possible limitation until additional studies done.
I have said this before, and I’ll say it again: Creatine (as monohydrate!) is one of the few supplements I would take and recommended if I didn’t exercise at all.
BTW: The dose of creatine was 3 g/day for the first week and 5 g/day for another 7 weeks.

The prevalence of testosterone deficiency (aka hypogonadism or Late Onset Hypogonadism), defined as total testosterone (TT) at or below 300 ng/dl is close to 40% in men aged 45 years and older presenting to primary care offices in the US.1 Year 2006 is was estimated that more than 13.8 million men over 45 years of age visiting a primary care doctor in the United States have symptomatic androgen deficiency.1
A large international web survey using the Aging Males’ Symptoms (AMS) questionnaire showed the prevalence of symptomatic testosterone deficiency to be 80% in men aged 16–89 (mean 52 years).2 It is notable that in the survey 40% of respondent were at younger ages when ‘Late Onset Hypogonadism’ is generally not believed to be occurring.2 The surprisingly high prevalence of raised scores indicative of testosterone deficiency in the younger age groups may be due to the increasing prevalence of conditions in these age groups known to reduce testosterone levels, such as obesity 3-7 and chronic work stress. 8-10 Stress-induced cortisol elevation, by increasing SHBG, lowers the free active fraction of testosterone and thereby reduces its action.11
This large and rising prevalence of testosterone deficiency is gaining recognition among doctors and patients alike. However, while testosterone replacement therapy (TRT) confers great benefits to men with sup-optimal testosterone levels, it also comes with some side-effects which are especially relevant for men who wish to have a family…Many testosterone users and even clinicians 12 are unaware that testosterone supplementation suppresses the hypothalamic-pituitary-gonadal (HPG) axis and may result in infertility…
Whey protein has become a staple nutritional supplement with both athletic populations requiring the highest possible quality protein to help recuperate from exercise, and those interested in the various health and disease fighting benefits of whey.
However, whey is a complex protein which leads to various questions regarding this biologically active protein. Some of this confusion has stemmed from the marketing efforts of various companies competing for sales in a very competitive market. Some of the confusion stems from a simple misunderstanding of the science of whey.
This Q&A will attempt to address some of the most common questions regarding whey as it applies to some of the major differences between types of whey, such as whey concentrates and whey isolates and other common sources of confusion. For in-depth information on whey and its many potential health benefits, read the “50 Shades Of Whey”
Q1:“What are the essential differences and advantages/disadvantages of each type of whey protein? Isolate, concentrates?”
DHEA (dehydroepiandrosterone) is most known for being a pro-hormone which in the body gets converted to testosterone and estrogen. It is a long held view that DHEA exerts all its effects via conversion to testosterone and estrogen. However, recent studies show that DHEA also has several interesting non-hormonal actions…
A few days ago, Jan 29th 2014, a controversial study was published showing that men aged 65 years and older, had a two-fold increase in the risk of heart attack in the 90 days after filling an initial testosterone therapy (TT) prescription, regardless of cardiovascular disease history. Among younger men below 65 years of age with a history of heart disease, the study reported two to three-fold increased risk of MI in the 90 days following an initial TT prescription (and no excess risk was found in younger men without such a history).
This study has stirred up heated discussions and media headlines. Let’s dissect it and look under the hood…
Many studies have highlighted the importance of investigating all major hormones, and correcting deficiencies and imbalances if present.[1-8] Given the known mechanisms of testosterone and GH/IGF-1 in building muscle (and possibly also DHEA in elderly) it is reasonable that age-related low levels of anabolic hormones contribute over time to sarcopenia and frailty.[1, 2, 4, 7, 9, 10]
Thus, multiple small effects in aggregate can lead to adverse loss of muscle and disability. In this scenario, if replacement was to occur, it would require lower doses of multiple anabolic hormones. An added benefit to this approach would be fewer side effects from the use of lower hormone doses . In addition, multiple anabolic hormone replacement might also have beneficial additive and/or synergistic effects.[11-13]
A notable study investigated whether supplementation with testosterone and GH together, in physiological doses, results in greater improvements in body composition and muscle performance in older men, compared to testosterone supplementation alone…
The consequences of low testosterone levels have been primarily investigated in middle-age and older men. However, low-T in young men aged 20-39 years can confer health risks as well…
