I have seen NO changes in my blood sugar. I can NEVER get them on the phone and the line is always busy! Sometimes they just close their office during a normal business day, and you can't contact them. They don't have an email contact and the only way you can return their product is to have a "Return Number." Well how do you get a Return Number if you can't get them to answer the phone? I have even left a phone message after waiting 15 minutes on the phone to return my call. Asked them to call me because I wanted to cancel future orders and they never called me back.
Bottom Line: No, I would not recommend this to a friend
