I bought the three-bottle starter pack and could tell a positive difference with my stomach issues almost immediately, but as far as weight loss or appetite suppression, nothing. By the end of the second bottle, I decided it wasn't working for what I wanted it to and tried to contact customer service to return the third bottle, but could not reach a live person and never received responses to my multiple emails.
Their claims to "want your feedback" are obviously not true. So buyer beware, either start with one bottle and decide, or go into the purchase knowing you are taking a risk.
Bottom Line: No, I would not recommend this to a friend
