How do you “break into” the supplement industry? What experience and educational background do you need? In this vid I cover the truth behind how different people get into the supplement industry.
In this vid, I discuss the popular “Testosterone booster” supplement D-Aspartic Acid (DAA) and update my opinions of this general category of supplements.
Study mentioned in the vid:
D-Aspartic acid supplementation combined with 28 days of heavy resistance training has no effect on body composition, muscle strength, and serum hormones associated with the hypothalamo-pituitary-gonadal axis in resistance-trained men
Department of Health, Exercise and Biochemical Nutrition Lab, Human Performance, and Recreation, Baylor University, Waco, TX, USA
It was hypothesized that d-aspartic acid (D-ASP) supplementation would not increase endogenous testosterone levels or improve muscular performance associated with resistance training. Therefore, body composition, muscle strength, and serum hormone levels associated with the hypothalamo-pituitary-gonadal axis were studied after 28 days of resistance training and D-ASP supplementation. Resistance-trained men resistance trained 4 times/wk for 28 days while orally ingesting either 3 g of placebo or 3 g of D-ASP.
Data were analyzed with 2 × 2 analysis of variance (P < .05). Before and after resistance training and supplementation, body composition and muscle strength, serum gonadal hormones, and serum D-ASP and d-aspartate oxidase (DDO) were determined. Body composition and muscle strength were significantly increased in both groups in response to resistance training (P < .05) but not different from one another (P > .05). Total and free testosterone, luteinizing hormone, gonadotropin-releasing hormone, and estradiol were unchanged with resistance training and D-ASP supplementation (P > .05).
For serum D-ASP and DDO, D-ASP resulted in a slight increase compared with baseline levels (P > .05). For the D-ASP group, the levels of serum DDO were significantly increased compared with placebo (P < .05). [B]The gonadal hormones were unaffected by 28 days of D-ASP supplementation and not associated with the observed increases in muscle strength and mass.
Therefore, at the dose provided, D-ASP supplementation is ineffective in up-regulating the activity of the hypothalamo-pituitary-gonadal axis and has no anabolic or ergogenic effects in skeletal muscle.
Nutritional supplement companies want people to believe the products they sell are made by them in pharmaceutical grade facilities using the best possible ingredients using the latest science,
and designed people with qualifications to formulate such products. The actual truth is nothing like that. In this episode of BrinkZone radio I reveal how the vast majority of nutritional supplements are

Here’s my “take home” on this latest study causing all the hoopla that found an association to “fish oil” and prostate cancer. For those who want to real nitty gritty on this study, see article by Dr. Lopez HERE.
Another great article from Dr. Lopez that examines in objective detail what risks, if any, long chain fatty acids (the “fish oils” EPA/DHA would be in that category) present to the prostate. His prior article on fish oils can be found HERE.
Long-Chain Omega-3 Fatty Acids: Friend or Foe to Prostate?
More than meets the eye to recent controversy over omega-3 levels and prostate cancer risk—Lets take a closer look
Hector Lopez, MD, CSCS, FAAPMR
A large-scale prospective case-cohort study evaluating plasma fatty acid levels and prostate cancer risk, published in JNCI (Journal of the National Cancer Institute) online ahead of print on July 10th, 2013 has created quite the stir amongst media, health care professionals, nutrition researchers, and the dietary supplement industry…Again! To quote the great Yogi Berra, “It’s like déjà vu, all over again.”
Can you trust it?
Do supplement companies fund research? Some do, some don’t, but what’s the important facts you need to know about supplement company funded research?
I cover that topic in this vid!
Growth Hormone (GH) supplements have been around forever, and have made a recent come back. Are they legit? Do they increase muscle mass or reduce body fat as claimed? I cover these supplements in this vid!
BTW, My books on the right column of this page cover GH supplements in depth if interested in more info ===>
A common question I get is regarding creatine added to pre workout drinks. Many companies put creatine in their pre workout supplements, and many people add creatine their home made pre workout drinks, but should they?
I have the facts on creatine being added to pre workout drinks in this vid!
