Casein or whey, which is best?
The casein vs. whey issue seems to contribute to much confusion for people. In this vid, I touch on the essential differences between them. I go into much more depth in the “pages” of Bodybuilding Revealed on casein, but an article that goes into depth regarding the shortcomings of the studies comparing these two proteins – as well as additional info on the whole pre and post workout nutrition topic – is mentioned in this vid and found HERE.
Below is a brief discussion on DHEA as “muscle builder” and such. DHEA may have specific benefits to women, and I recommend reading my write on that topic HERE for additional info.
Below are my comments on NO/Nitric Oxide supplements, with a few comments on a recent study. Below the vid is the abstract for that study, and the link to the full paper for those who wish to get the details. I have never had much faith in this category of supplements – for a variety of reasons – and this study adds additional confirmation to my generally low opinion of NO/Nitric Oxide formulas:

Abstract
Background
We compared Glycine Propionyl-L-Carnitine (GlycoCarn®) and three different pre-workout nutritional supplements on measures of skeletal muscle oxygen saturation (StO2), blood nitrate/nitrite (NOx), lactate (HLa), malondialdehyde (MDA), and exercise performance in men.
Methods
Using a randomized, double-blind, cross-over design, 19 resistance trained men performed tests of muscular power (bench press throws) and endurance (10 sets of bench press to muscular failure). A placebo, GlycoCarn®, or one of three dietary supplements (SUPP1, SUPP2, SUPP3) was consumed prior to exercise, with one week separating conditions. Blood was collected before receiving the condition and immediately after exercise. StO2 was measured during the endurance test using Near Infrared Spectroscopy. Heart rate (HR) and rating of perceived exertion (RPE) were determined at the end of each set.
Results
A condition effect was noted for StO2 at the start of exercise (p = 0.02), with GlycoCarn® higher than SUPP2. A condition effect was also noted for StO2 at the end of exercise (p = 0.003), with SUPP1 lower than all other conditions. No statistically significant interaction, condition, or time effects were noted for NOx or MDA (p > 0.05); however, MDA decreased 13.7% with GlycoCarn® and increased in all other conditions. Only a time effect was noted for HLa (p < 0.0001), with values increasing from pre- to post-exercise. No effects were noted for HR, RPE, or for any exercise performance variables (p > 0.05); however, GlycoCarn® resulted in a statistically insignificant greater total volume load compared to the placebo (3.3%), SUPP1 (4.2%), SUPP2 (2.5%), and SUPP3 (4.6%).
Conclusion
None of the products tested resulted in favorable changes in our chosen outcome measures, with the exception of GlycoCarn® in terms of higher StO2 at the start of exercise. GlycoCarn® resulted in a 13.7% decrease in MDA from pre- to post-exercise and yielded a non-significant but greater total volume load compared to all other conditions. These data indicate that 1) a single ingredient (GlycoCarn®) can provide similar practical benefit than finished products containing multiple ingredients, and 2) while we do not have data in relation to post-exercise recovery parameters, the tested products are ineffective in terms of increasing blood flow and improving acute upper body exercise performance.

In this vid, I address the issue of dose, quality, and other essential issues regarding fish oils. For those who want to see additional info, recommended brands, etc, read: Getting The Most From Supplements: Fish Oil Example!
Does creatine monohydrate cause “bloating” as is claimed by sellers of alternative forms and some users? In this vid, I address that issue:
Many people are confused as to what’s the difference between flax oil vs fish oils. This vid briefly covers that topic and should help reduce confusion. Enjoy! 
A common claim made by various companies selling forms of creatine that compete with monohydrate, is that it’s “unstable.” I address that issue in this new vid:
Below are some brief comments on creatine monohydrate vs. the 9,834,734,493 “other” forms all claiming to be superior. For more details byond the vid below, see The Creatine Graveyard

I briefly cover “side effects” of creatine. If you want more depth and detail, see the various creatine articles here on the site, and or read the full report I wrote up.
