The whole topic of Herbalife withoin our industry is, as Steve says, seen as little more than a huge and really rather pathetic joke. They are to almost anyone with half a brain operating a multi-level marketing scheme yet denied that for years. You can google the court cases and decisions.
Their products are... at best... poor. They sell a protein product here in the UK which is £20 (around $26 or so) for 250g. I can buy a kilo of whey protein concentrate for about £11-12 a pop. Their product woukld be £80 a kilo and is a basic soy concentrate. Their pricing is, of course, because of the levels of sellers. Local, regional, national and international. I probably misses a few levels ha ha.
The problem isn't even the products. It's the poor sellers. In order to make sales of any meaningful amount they sell to others. Only the very top make any decent money. What you end up with is people claiming to be nutritionists and dieticians who don't even know how bad their product is never mind be able to give even the tiniest bit of decent advice. Heck, I've seen examples where it look liked they made stuff up.
