It's been around a long time, one guy was selling in Bury St Edmunds 25 years ago, so it's nothing new. I think I am right in saying that their selling methods are aren't illegal, but they are as close to pyramid selling as the law will allow. I wouldn't touch it with a barge pole.
Just spotted this. I'm an official distributor for Herbalife, so if anyone wants to try it let me know and I can give you some more information I have 5 friends all using it and they've had great results within a few weeks. If you are going to try it though, only buy it from an official seller like myself, as there are a few fakes being sold at the moment on ebay :-/ Also I have the training to do your protein factor analysis, which is essential to know what Herbalife program will work for you personally. xx
