Peptides for Weight Loss: How They Work Alongside GLP-1 Medications
GLP-1 medications like semaglutide and tirzepatide are themselves peptides, and they remain the main driver of weight loss in a medical weight loss program. What a broader peptide protocol adds is everything GLP-1 alone doesn’t cover: preserving lean muscle during rapid weight loss, correcting the vitamin D and B12 deficiencies common in GLP-1 patients, and supporting energy through NAD+ and sermorelin. None of these replace the GLP-1 prescription. They’re layered on top of it, individualized after a full review of labs and goals, not sold as standalone add-ons.
