SHR # 2448 :: Metformin's False Status as a Wonder-drug for Longevity and Physique Goals PLUS MORE :: Jared Boynton and Taeian Clark - Metformin is promised to make already healthy people to live longer, leaner and healthier. The drug has been studied in humans since 1950, but its popularity as an anti-aging drug is very recent. And its not truly supported by the literature. All of its purported anti-aging effects in otherwise healthy people is all basically extrapolated. There are no long term studies that prove otherwise healthy people who took the drug lived longer than the control that didn't. People who believe its value fro anti-aging will fight you if you disagree with them!
