This is hardly the answer you’re looking for - I don’t have any experience with the actual product, but I am extremely skeptical.
Once while I was living in the Provo, UT area, I applied for a job in the newspaper, only to be sucked into their MLM recruiting spiel when I showed up for the “interview”. The location was in a newly-leased office space; it looked like they’d been there less than a week, but there were hundreds of people crammed into this tiny area. They were very aggressive about talking me into becoming a drone, and kept pushing me and shuffling me from “interview” to “interview” around the office area, asking me repeatedly if I thought TN was the greatest thing ever, offering to sell me the introductory video and sales package, and generally refusing to answer my questions. (One question, “what is Tahitian Noni?” went unanswered until the 3rd or 4th handler.) I eventually realized that I could not leave the building without getting rude. On my way out, as I was shoving my way past my handler to get to the outside door, the receptionist asked me if I wanted some flyers to spread around.
When I got outside, shaking and sweating profusely, I realized that, for the first time in my life, I was literally sick with rage.
This particular operation was gone, lock stock and barrel, within a month. Whether they were shut down, or ran out of drones or money, or moved to another location, I have no idea.
One rather telling factoid about TN: it’s based in Provo, Utah. Lots of shady MLM companies thrive there, feeding on the enthusiasm and cold-calling expertise of freshly returned Mormon missionaries. It’s been my experience that the greatest customer base for these companies are their own salespeople.
Another data point which only serves to fuel my skepticism: it’s a one-size-fits-all-ailments commodity. In other words, snake oil. If you really want to get into this business, I’m sure you could come up with cheaper (and probably more effective) on your own.
