I work out on a daily basis and this product seems to enhance my endurance. i dont get out of breath. i play basketball alot and i can play 5 full court games and i still have my breath. i went and helped my buddy move out of his house and we were lifting furniture all day. i felt really good and seemed to be able to breathe with ease. i plan on using this product on a daily basis.
Tried it this morning and for the first time with the sample I got in the mail and dropped a minute on my run time on my PT test. I had my doubts at first but it defiantly lived up to its word.
