I cant beleive people support the Life Extention foundation, its the New Age allopath in disguise! Just like the pharmaceutical companies one must constantly being trying new drugs or what they call suppliments taken from natural sources isolating an element and charging up the wazoo for it! Old scam mew name is all! Most supps are conjured up are made by same people who make pharmaceuticals! The only difference is these supplements have less noticible side effect but are just as useless! Metformin is just slow death!
