Peptides are short chains of amino acids, the building blocks that make up proteins. Many peptides occur naturally in the body, and many work like tiny messengers signaling parts of your body to do specific things.
What makes them interesting to researchers is their specificity. Different peptides interact with different targets in the body, like keys cut for particular locks. That precision is why peptides are an active area of scientific study across a range of biological processes, from hormone signaling to tissue repair.
You’ve probably heard of GLP-1 medications like semaglutide and tirzepatide. Yes, those are peptides too.
Peptides are a fast-moving and heavily regulated area. Only certain ones are FDA-approved, and many remain investigational. At PreventiveMD, we only offer what’s legally available and our licensed providers can help you understand the options that are right for you and what the evidence does and doesn’t yet show.
