## Resource

Peptides like BPC-157, TB-500, CJC-1295 and retatrutide are among the hottest trends for optimizers, gym bros, looksmaxxers and the longevity crowd. But is it wise to inject bioactive molecules into the bloodstream that haven’t passed the drug approval process? In this episode, Marty and Stu welcome the Harvard- and Stanford-educated Leigh Baxt, who mythbusts about peptides and other panaceas on Instagram @sciencemomscicomm. Baxt is a translational scientist who specializes in drug development. She points out the many problems with injecting peptides into the body, including the major one that many of these peptides are activating biological pathways that cancer cells love. In this episode we discuss the following questions: —What are peptides? —Why are peptides so hot? —Are peptides safe? —What do peptides do? —What is a wolverine stack? We also provide a quick guide to peptides like BPC-157, TB-500, CJC-1295 and retatrutide, and walk through the drug-approval process that protects human beings from predatory marketing. The episode concludes with a discussion of what Marty, Stu and Leigh think is so wrong about promoting peptides to young people. What scientific evidence supports peptide use?
