I'm suspicious of any product sold by multi-level marketing (MLM) or that comes up often in connection with the word "scam." I wish I could find some research to prove or disprove whether Agel is legitimate.
The Better Business Bureau of Utah has received 5 complaints about Agel in the past 3 years, all of which were resolved. (Report on Agel) I'd feel more comfortable if Agel were a BBB member. In any case, if you do decide to try Agel and have a problem, you can contact the BBB yourself.
