Book a real prescriber this week, and lift three days a week from your first shot. ## Why it works Tirzepatide is semaglutide's stronger successor. One molecule hits two gut-hormone receptors instead of one. Under the names Mounjaro and Zepbound, it posts the biggest weight-loss numbers of any approved drug. Hits GLP-1 and GIP receptors together: two hormone levers, one molecule. In head-to-head trials, hitting both receptors beats hitting one on both glucose and weight. ## The doses the studies used | Study / Context | Route | Dose | Duration | | ------------------------------------------------ | ------------ | ------- | --------------------------- | | Standard Dose Escalation (FDA-Approved Labeling) | Subcutaneous | 2.5 mg | Weeks 1-4 (initiation dose) | | Standard Dose Escalation (FDA-Approved Labeling) | Subcutaneous | 5 mg | Weeks 5-8 | | Standard Dose Escalation (FDA-Approved Labeling) | Subcutaneous | 7.5 mg | Weeks 9-12 | | Standard Dose Escalation (FDA-Approved Labeling) | Subcutaneous | 10 mg | Weeks 13-16 | | Standard Dose Escalation (FDA-Approved Labeling) | Subcutaneous | 12.5 mg | Weeks 17-20 | | Standard Dose Escalation (FDA-Approved Labeling) | Subcutaneous | 15 mg | Week 21 onward | ## What to watch Who should avoid Same exclusions as the class: medullary thyroid carcinoma or MEN2 history, prior pancreatitis, pregnancy.
