What people say about Metformin and performance
“Berberine has done zero for my pre diabetic glucose levels or weight. Metformin has and I changed nothing else.”
“Recently, he stopped because it was found to interfere with some other important function (muscle building?, I can't remember), so he stopped taking it. He said the benefits did not outweigh the costs.”
“My doctor prescribed it for life extension purposes / increase insulin sensitivity. The main reason I stopped to was that it reduced exercise performance.”
“Metformin: 500 mg nightly. Mainly for theoretical longevity benefits... I recently reduced the dose because I value exercise adaptation, recovery, and performance.”
