Here is another interesting case study on effects of pre-workout drinks from the US National Library of Medicine National Institutes of Health. It is called Comparison of pre-workout nitric oxide stimulating dietary supplements on skeletal muscle oxygen saturation, blood nitrate/nitrite, lipid peroxidation, and upper body exercise performance in resistance trained men. Here is the background on the study:
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.
Here is the results:
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.

Talking about energy and formulated supplement for ultimate gains is really good to hear. For a fact that I'm also using a pre-workout supplement for a couple of months now. If some of you are hesitant to use this kind of pills, then you should do your assignments. What i mean is that, when you take this kind of supplement should be an FDA regulated. To give you an idea, you can visit the site and just click highlighted word.
