My relative sells this. He paid out thousands to get to the next level so he could get a discount. He is currently trying to unload closets full of this stuff at cost just to be done with it.
He claims atheletes use it, but several are suing because banned things(for sports) were in some. Also, what made him lose weight was not eating out, not drinking a case of cokes, not drinking a venti Starbucks, etc...
He also started exercising. He was morbidly obese and just doing the right thing made the weight come off. It is weird but he has leveled off at 200 pounds and is using double the products with no luck. He is still exercising, not eating out a lot, and stuff.
His brother was as large and is still overweight while using it. He doesn't try to sell to family because he had to refund money to several.
No matter what discount you get, I would NOT invest and become a salesperson for any MLM ever. Plus, some companies get bonuses for ordering a full case. Ask the salesperson if he needs just x more dollars to get the full case and bonus would he or she sell you the stuff you want at the discounted price?
