Step 1
GLP-1 & GIP Double Action Weight Loss: Tirzepatide
Tirzepatide Injection is a physician-guided GLP-1/GIP body composition protocol for patients who want appetite control, reduced food noise, and stronger metabolic momentum. Tirzepatide works through two incretin pathways, GLP-1 and GIP, which are involved in hunger, satiety, blood sugar regulation, and how the body manages energy.
Whether you have 50+ pounds to lose or just 10, this is a convenient, efficient, and effective solution built to help you see change on the scale and in the mirror. The once-weekly injection format makes it simple to stay consistent while following a structured fat-loss plan.

- Supports appetite and cravings by working with GLP-1/GIP, hormone pathways your body already produces after eating
- Helps steady blood sugar alongside insulin response, so results don't come from restriction alone
- Built to work with your metabolism rather than fight it, no crash-diet mechanism involved
- Before anything is prescribed, a licensed provider walks through your health history, current medications, and goals with you
- Comes through a physician-guided program you can trust: U.S. pharmacy dispensed, LegitScript certified, third-party tested
Most patients follow a physician-guided protocol in a 1-month, 3-month, or 6-month plan, then reassess based on progress, goals, and tolerance. Protocols can be customized for new patients, switching medications, and maintenance when appropriate. Your provider will adjust dosing as needed and help determine the best next phase.
- Use as a subcutaneous injection once weekly on the same day each week, or exactly as prescribed by your provider. Your medication arrives ready to inject with no reconstitution needed. Rotate injection sites and follow the instructions included with your medication.
- Do not change your dose or frequency unless directed by your provider.
- Weeks 1–2: Appetite shifts often begin. Many patients notice reduced food noise, smaller portions, and better control around cravings.
- Weeks 3–8: Momentum builds. Consistency becomes easier, hunger feels more manageable, and weight-loss trends may become more predictable.
- Weeks 8–24+: Compounding results. With protein, strength training, steps, and sleep in place, patients may see more visible changes in waistline, definition, and body composition.
What's Inside &
Why It Works
Tirzepatide
As a dual GLP-1/GIP receptor agonist, tirzepatide activates two incretin hormones, GLP-1 and GIP, that your body produces naturally after eating. This is the same active ingredient in the FDA-approved medications Mounjaro (for type 2 diabetes) and Zepbound (for chronic weight management), the formulation offered through Mankind Health is a separate compounded preparation, and your provider can explain exactly how the two differ. Rather than publishing dosing on this page, your provider determines what's appropriate once they've reviewed your history.

asked questions
Mankind Health offers programs for both. A provider reviews your medical history, current medications, and goals to determine whether tirzepatide is appropriate and how it should be prescribed.
Semaglutide acts on the GLP-1 receptor. Tirzepatide acts on both the GLP-1 and GIP receptors. That difference does not tell you which treatment is right for you; your provider can discuss the options based on your history and goals.
Tell your provider about all prescriptions, peptides, supplements, and over-the-counter products you use. They can review potential risks before recommending any combination.
Tell your provider about your hormone therapy and how you take it. If you use an oral hormonal contraceptive, mention that specifically: tirzepatide can reduce its effectiveness, particularly when starting treatment and after dose increases.
No extreme dieting is required. The goal is a sustainable calorie deficit with enough protein, fiber, and resistance training to protect muscle, support digestion, and keep results looking athletic. We generally recommend at least 1 gram of protein per pound of goal body weight per day for women, with many working up toward 1.5 grams per pound when appropriate. For men, pushing closer to 2 grams per pound of goal body weight can be even better for supporting lean muscle, satiety, and body composition. Adding fiber supplementation can help support digestion and regularity, and resistance training should be part of the plan to help preserve muscle while fat loss progresses.
