This study shows that new anti-diabetic drugs, particularly GLP1-RA and Tirzepatide, are the most effective in inducing weight loss in patients with type 2 diabetes. Interestingly, exenatide appears to be the only GLP1-RA that induces a mild weight loss.
Pharmacol Res, 2021 ↗“Tirzepatide works so well! Do some research in the r/peptides subreddit and the r/tirzepatide subreddit. It's the most effective thing I've ever seen for appetite suppressant.”
