Hi Aiga - I honestly don't have a clue about this company so I entered herbalife into google search to see what type of product it was and just saw thousands of entries with scam in the headline - I am just always wary of any type of pyramid type company - anyone I have ever known over the years that got involved in those type of companies ended up losing money - here is one of the top entries I found Pyramid Scheme Alert
I suppose on the internet though you will always get two sides to the story and maybe all those bad comments and entries are from disgruntled people and maybe the company is fine... I honestly don't know.
I tried it for a while after I had my first baby (nine years ago lol). I lost some weight, but didn't notice anything life changing. My mom sold it for a while and used it, but it didn't do a lot for her either.
