peptide vs semaglutide GLP-1 vs. Ozempic vs. Wegovy Peptide Biohacking? Semaglutide vs. Tirzepatide

Patients can lose up to 10%-16% of their body weight over 12 to 15 months by combining semaglutide with healthy habits, a balanced diet, and exercise

Next-generation agents include CagriSema (semaglutide + cagrilintide, NDA filed December 2025, showing 22.7% weight loss), retatrutide (triple GIP/GLP-1/glucagon agonist, 28.7% weight loss in Phase 3), and orforglipron (oral non-peptide GLP-1, submitted to FDA)

Tesamorelin is a synthetic analogue of growth hormonereleasing hormone (GHRH)

Retatrutide is still investigational and is not FDA-approved, but this readout matters because it gives the peptide community a more specific map of dose, response, tolerability, and what still needs to be watched
