Weight Loss
Best peptides for weight loss.
Weight loss peptides — particularly GLP-1 and dual GLP-1/GIP agonists — work by regulating appetite, slowing gastric emptying, and improving insulin sensitivity. They have become some of the most studied compounds in modern metabolic medicine.
8 peptides in this category
A long-acting GLP-1 receptor agonist studied for its effects on appetite, satiety, and glucose regulation.
A dual GIP and GLP-1 receptor agonist with strong effects on appetite, glucose handling, and body composition.
An investigational triple agonist of GLP-1, GIP, and glucagon receptors producing some of the largest weight-loss results recorded in trials.
A small-molecule oral GLP-1 receptor agonist studied as a needle-free alternative to injectable incretin therapy.
A modified C-terminal fragment of human growth hormone designed for fat-loss effects without the broader anabolic action of full HGH.
A long-acting amylin analog developed to be combined with semaglutide for enhanced weight loss (CagriSema).
A dual GLP-1 / glucagon receptor agonist developed by Innovent and Eli Lilly for type 2 diabetes and weight loss.
A weekly dual GLP-1 / glucagon receptor agonist developed by Boehringer Ingelheim and Zealand Pharma for obesity and MASH.
