01 / THE BASICS
What is peptide therapy?
Understand the language before comparing the claims.
Learn the essentials ↗02 / THE EVIDENCE
Read beyond the headline.
Separate a promising mechanism from a patient benefit.
Use the evidence framework ↗03 / THE CONVERSATION
Ask better questions.
A practical checklist for discussing a treatment with a clinician.
Take the checklist ↗Our editorial approach
Every claim needs context.
A study’s design, population and limitations matter as much as its headline result. Our guides name the evidence type and link to the source.
