I think most golf and tennis players would take Anatabloc not so much to make them win (they are not pro athletes) as to just enable them to play. If the product can do that, it is doing its job.
But Fred Couples isn't taking ABloc in order to play. At this year's Master's after being in contention in the second round, there was an article by Paul Mahoney where he discussed Freddy's future and Couples gave alot of insightful quotes. One thing disclosed was that Freddy regularly takes epidural-like pain injections.
"He lollops along in what looks like slippers with that loosey-goosey stride of his as if he is heading for the beach back home in California. The reality is that he wouldn't be walking at all if it weren't for regular pain-killing injections in his ailing back that, apparently, are so strong they are like epidurals."
So back to my point about the Brand Ambassador's, they clearly have shown talent in the year prior to taking ABloc. And likely took ABloc to help enable them to play. But if their level of play has dropped, doesn't that suggest that ABloc isn't helping them to play? And in Freddy's case, a stronger medication is needed to play?
