Pyramid marketing like the old 1980's Herbalife brand marketing scheme comes quickly to mind.
First, let me start off with a quick observation on O2 Uptake, O2max and an athletes ability to turn O2 into fuel. We are all born with a certain ability to process O2 from the air into the lungs then through the body. By far, most O2 breathed in (even at elevated aerobic activity) is returned to atmosphere with the next exhale. Most of us will never perform an effort that hits our genetic max. If we have been a couch potato for a while, then we are only at a fraction of our genetic max. There is not a magic pill that will push our current ability to uptake O2 other than getting out in a well designed program, weighing our genetic optimum weight and having a spot on diet.
I reviewed the Advocare site and recognize several faces and names. When one punches up their profile (from an endorser list) most all are using their hydration drink which is not too different from 5 hour energy drink. I did not see a user of the product asked about. That doesn't mean much other than the folks pictured I recognize are not using it. Though I find it funny that Drew Breeze is on the front web page but did not make the endorser list.
I looked at the ingredient list and the largest ingredient is our friend protein. The next ingredient, Inosine was thought to be a possible performance booster; however, clinical trials dispute that claim. It is still included in some supplements. Rhodiola rosea is next and is a stimulant. It seems to have some benefit in treating depression but as an athletic performance booster, clinical studies are inconclusive (some higher, some not so). The other two ingredients would serve as an antioxidant as best I can tell.
I cannot see where this would be beneficial. There may be others who would offer a different thought. I would want to see something other than anecdotal studies before I trusted it. Sorry.
