What Peptides Actually Are
- Peptides are short chains of amino acids that act as signals telling cells what to do.

Medicinal Peptides Versus Trendy Injectables
- Some medically useful peptides (like Ozempic) are regulated prescription medicines with real therapeutic effects.
- Elliot Lawry notes Ozempic is a GLP-1 peptide used under prescription, contrasting it with unregulated TikTok products.
Popular Peptides Often Lack Human Trial Evidence
