The weight loss data is similar: For weight loss specifically, there is no meaningful clinical difference
Testing may include SAM, SAH, methionine, homocysteine, whole-blood histamine, copper, zinc, ceruloplasmin, urinary pyrroles, organic acids, lactate, pyruvate, glutathione-related markers, 8-OHdG and lipid peroxides when clinically appropriate
If your GIP receptors have desensitized alongside your GLP-1 receptors, switching to a pure GLP-1 agonist removes the GIP stimulus entirely, allowing those receptors to recover while you maintain GLP-1 mediated appetite suppression with a different agonist profile
Bottom line Tirzepatide (Mounjaro, Zepbound) and semaglutide (Ozempic, Wegovy, Rybelsus) are used to treat conditions such as Type 2 diabetes and sleep apnea and are also often used for weight loss (whether FDA-approved or off-label)
