Positive experiences
“Metformin currently has enough data for me personally to feel comfortable not only taking it myself (and my wife), but also recommending it to my patients.”
“Metformin: 500 mg nightly. Mainly for theoretical longevity benefits... I recently reduced the dose because I value exercise adaptation, recovery, and performance.”
“I have never taken glp but was having similar nonsensical results and metformin fixed it instantly.”
Negative and mixed experiences
“Berberine has done zero for my pre diabetic glucose levels or weight. Metformin has and I changed nothing else.”
“2 days with Metformin and that’s gone. I feel like I did when i was in my 30’s.”
“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.”
“Personally, I used metformin for 2 years, though I stopped for a multitude of reasons.”
“Terrible side effects for me stomach wise and didnt particularly impact my blood sugar either...A1c went from 5.9 to 5.6 on metformin.”
“Been on it for 17 years. Only recognizable benefit is to reduce my blood sugar. No side effects noted, dosage for 14 years has been 2,000 mg a day, split half in morning and half in evening.”
