Peptides are short chains of amino acids, linked together by peptide bonds. ¹ They are smaller than proteins, which are also chains of amino acids. ² Peptides act as signaling molecules in the body, carrying messages between different cells and tissues. ³ They play a role in various physiological processes including hormone regulation, growth and development, and immune function.

Semaglutide: This peptide mimics a natural hormone called GLP-1 that helps control blood sugar and appetite. It works by stimulating insulin release, slowing gastric emptying, and reducing appetite, leading to weight loss and improved blood sugar control in people with type 2 diabetes. It is also approved for weight loss in people who are obese or overweight.

Tirzepatide: Similar to semaglutide, tirzepatide also works by mimicking GLP-1, but it also activates a second hormone called GIP. This dual action leads to even greater effects on blood sugar control and weight loss compared to semaglutide. It is approved for treating type 2 diabetes and is being studied for weight loss.

Retrutide: This is a newer peptide that is still in clinical trials. It acts as a triple agonist, meaning it activates three different receptors in the body: GLP-1, GIP, and glucagon. This combined action is thought to further enhance weight loss and blood sugar control compared to other peptides..
