I have used it several times for long distance running taking it about 30 minutes prior to my run. It gives you great energy (due to the high caffeine amounts) and the Nitric Oxide pumps the blood through your body faster and harder.  However, I stopped taking it.  It will definitly dehydrate you and you will need to drink 4x more water than usual.  It gave me headaches. It is mainly used for pumps when lifting.  One other thing, it dissallows nutrients to transfer into your muscles.  Muscle cramps begin to develop due to NO xplode. I would not recommend it.

Good Luck!

beerpace, you are too funny.

What is "BSN" - bull sh nausea?  Another "secret formula" that the medical profession doesn't want any of us to know about but you can buy it - just make the $$$ check out to "cash" in three easy installments.

FaithDawg, i understand your concern with wanting to improve your endurance and your recovery, and this is indeed the forum to find info. 

When you see "award winning", you can bet that it's an in-house award and that any "research results" were crudely done with a select group of people who have a financial interest in the product.  It's like a high school flunkie correcting their own exams and giving themselves a good grade because gramma promised them $5.

Luckily, you can find out legimate results by entering the product in the Google Scholar search engine and looking for peer-reviewed articles. For instance, there's a beverage called FRS which was commissioned by the Dept of Defense to be tested in the Western 100 to see if it's antioxidant qualities helped, because that can be carried over to our military. I don't know what the results were, but FRS was nicely researched by major uiniversities. If BSN... is in good scientific standing, let us know. Also, 1/3 people will react positively to the placebo effect. Take that for what it's worth.

I have been using Myoplex Lite shakes and bars by EAS right after I go on a 5 1/2 mile hike and find there is a huge difference. I am getting the protein I need to help refuel and rebuild muscles and its toning me up in time for summer which is ridiculously hot here in Los Angeles. Anyone else try it?

Oh and L-Glutamine is god for brain power mostly which might be why you are getting more out of your work out with it. My dad used to run a health food store.

Check out Carnitine as well but BEWARE that it has a tendency to give you hormonal rushes and men and women can get a little agro on it after taking it.
