Tirzepatide is administered as a once-weekly subcutaneous injection Currently, Tirzepatide is marketed under the brand name Mounjaro, primarily for type 2 diabetes, though its being studied for obesity treatment as well
Some people find Mounjaro gives more constipation or bloating, while Wegovy causes more nausea early on
The Core Difference: Two Receptors vs Three Tirzepatide activates: GLP-1 receptor (appetite suppression, glucose control) GIP receptor (synergistic metabolic effects) Retatrutide activates: GLP-1 receptor GIP receptor Glucagon receptor (thermogenesis, direct fat oxidation) That third receptor is the key difference
In addition to detoxification, glutathione is involved in DNA synthesis and repair, protein synthesis, and immune system support
GLP-1 is the satiety hormone, explains Srivastava
What forms the bulk of the retail price2 of peptides is not the cost of manufacturing, but the capital infrastructure: the regulatory burden, the cold chain logistics, the pen device (which sometimes costs more than the drug itself), and, above all, the return needed to justify $9 billion in the initial R&D of these GLP-1 drugs
