I have bought products from advanced bionutritionals. They SAY they have a unconditional money back guarantee. That is a lie. I have been trying for over 2 months to get my money back. When you call they say they need to research this and never get back to you. They are a bunch of liars. I have taken their newsletters for many years. They are just a bunch of pill pushers and their guarantees are not worth the paper they are printed on. If they will just refund my money for their worthless products, I will stop posting these comments. Buyer beware of Advanced Bionutritionals!
