From 2,000+ patients · Tirzepatide is already seeing results
Tirzepatide is an FDA-approved GLP-1 receptor agonist for chronic weight management. In the STEP 1 trial (NEJM, 2021), semaglutide achieved an average 14.9% body weight loss. Weight Method offers Tirzepatide starting at $297/month, prescribed by licensed providers with direct shipping.
Key Fact
Tirzepatide is a dual GIP/GLP-1 receptor agonist that achieved 22.5% average body weight loss at the 15mg dose over 72 weeks (SURMOUNT-1 trial, NEJM 2022) — the highest of any FDA-approved anti-obesity medication. Sold as Zepbound for weight loss and Mounjaro for diabetes, it is a once-weekly injection. At Weight Method, tirzepatide starts at $349/month.

How does Tirzepatide work for weight loss?
Tirzepatide activates both GIP and GLP-1 receptors simultaneously, producing 20-25% average body weight loss — the highest of any FDA-approved medication.
Tirzepatide works through a unique dual-agonist mechanism, activating both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) receptors. While GLP-1 suppresses appetite and slows gastric emptying, GIP enhances fat metabolism and improves how your body processes and stores energy. This two-pronged approach addresses weight from multiple biological pathways, which is believed to explain why tirzepatide produces greater average weight loss than single-receptor GLP-1 medications. The combined effect helps reduce hunger, improve insulin sensitivity, and promote sustained fat loss.
What is the Tirzepatide dosing schedule?
Start at 2.5mg weekly for 4 weeks, increase to 5mg, then escalate in 2.5mg increments monthly up to a maximum of 15mg.
Tirzepatide follows a carefully structured dose-escalation schedule to optimize tolerability. Treatment begins at 2.5mg once weekly for the first four weeks, then increases to 5mg for the next four weeks. After that, your provider may increase your dose in 2.5mg increments every four weeks -- progressing through 7.5mg, 10mg, 12.5mg, and up to a maximum of 15mg -- depending on your response and tolerance. Most patients find their optimal maintenance dose between 10mg and 15mg. Your Weight Method provider will tailor the escalation timeline to your individual progress and comfort level.
What are the common side effects of Tirzepatide?
Common side effects include nausea, diarrhea, decreased appetite, and mild injection site reactions, typically subsiding as the body adjusts to treatment.
The most common side effects of tirzepatide are gastrointestinal, including nausea, diarrhea, decreased appetite, vomiting, constipation, and injection site reactions such as mild redness or itching. These side effects are most frequent during the initial weeks and after dose increases, and they typically diminish as your body adapts. The slow dose-escalation protocol is specifically designed to reduce GI discomfort. Rare but serious side effects may include pancreatitis, gastroparesis, and allergic reactions; your Weight Method provider will assess your full health profile before prescribing tirzepatide.
Who qualifies for Tirzepatide treatment?
Adults with BMI ≥30, or BMI ≥27 with weight-related conditions. Often recommended for patients needing more aggressive weight loss than semaglutide provides.
You may be a candidate for tirzepatide if you have a BMI of 30 or above, or a BMI of 27 or above with at least one weight-related comorbidity such as type 2 diabetes, obstructive sleep apnea, or cardiovascular disease. Tirzepatide is often recommended for patients seeking more aggressive weight loss or those who have not achieved sufficient results with other GLP-1 medications. You must be 18 or older and not pregnant, planning pregnancy, or breastfeeding. A history of medullary thyroid carcinoma or MEN 2 is a contraindication. Weight Method's free quiz helps determine if tirzepatide is the right fit based on your BMI, health history, and goals.
