The science of metabolic peptides.

Understand the Science

Start with how these peptides actually work, then go deep on each compound or compare them side by side.

A plain-language overview of how GLP-1, GIP, and glucagon receptor agonists curb appetite and burn energy — pick a compound to see its pathway.

An interactive side-by-side comparison of the three leading metabolic peptides — receptors, weight-loss results, FDA status, and side effects.

An interactive timeline of GLP-1 receptor agonist development, from the first incretin discoveries to the latest retatrutide trials.

How retatrutide's triple GLP-1 + GIP + glucagon mechanism drives the largest weight loss yet seen in trials, plus its profile and status.

How tirzepatide stacks GLP-1 and GIP for greater weight loss than semaglutide, with its key trial results and profile.

How semaglutide works as a single-receptor GLP-1 agonist, its headline trial results, and where it sits among the metabolic peptides.
