Peptides are short chains of amino acids — the building blocks of proteins. Unlike full proteins, peptides are small enough to be easily absorbed by the body, allowing them to signal specific biological processes like muscle repair, fat metabolism, and immune response.
Over 7,000 naturally occurring peptides have been identified. Researchers have studied many of these for their potential to support weight management, recovery, cognitive function, anti-aging, and more — with hundreds of published clinical studies.
These are some of the most researched peptides. Not sure which is right for you? That's exactly what our quiz helps with.
