Tirzepatide Dosage Chart: A Quick Guide
Key Takeaways
- Tirzepatide (the active ingredient in Zepbound® and Mounjaro®) is a once-weekly injection that’s FDA-approved for weight management and type 2 diabetes.
- It’s dosed in milligrams (mg), not insulin-style “units,” and almost everyone starts at 2.5 mg per week.
- The dose is raised slowly — by 2.5 mg at a time, no sooner than every four weeks — in a process called titration that keeps side effects manageable.
- The maximum dose is 15 mg weekly, but many people get excellent results at a lower maintenance dose of 5 or 10 mg.
- At New You in Sarver, PA, tirzepatide is offered as part of a supervised medical weight loss program.
Tirzepatide has quickly become one of the most talked-about tools for weight loss and blood-sugar control. If you’ve just been prescribed it — or you’re weighing it as part of your journey at New You Skin & Body Spa — understanding how the dose works is the key to safe, comfortable, and effective results.
This guide answers the most common questions about tirzepatide dosing: how it’s measured, what the weekly schedule looks like, where you start, how high it goes, and how compounded versions differ. Think of it as the plain-language version of the dosing conversation you’ll have with your provider.
How Is Tirzepatide Measured?
Here’s a point that trips a lot of people up: tirzepatide is measured in milligrams (mg), not in the “units” people associate with insulin. Each injection delivers a precise milligram dose — pre-set inside a Zepbound® pen, or measured by your provider when a compounded formulation is used.
It’s taken once a week, and the timing matters more than you might expect. Picking one day and sticking to it — say, every Sunday morning — keeps a steady level of the medication in your system and gives you the most consistent results. If you ever need to switch your injection day, your provider can tell you how to do it safely.
Zepbound® Pen Strengths
Zepbound® is the FDA-approved, brand-name pen form of tirzepatide for weight management. The pens come pre-filled in six strengths, each designed to deliver a single weekly dose:
- 2.5 mg
- 5 mg
- 7.5 mg
- 10 mg
- 12.5 mg
- 15 mg
You don’t move through every strength on a fixed timetable. Instead, your provider starts you low and steps you up only as needed — which brings us to the dosing schedule itself.
Tirzepatide (Zepbound®) Dosage Schedule
The single most important idea in tirzepatide dosing is “start low and go slow.” The medication is begun at a low dose and increased gradually over several weeks — the titration process — so your body can adjust and side effects like nausea stay mild. Below is a typical titration schedule that mirrors the FDA-approved label.
| Weeks | Dose per Week |
|---|---|
| Weeks 1–4 | 2.5 mg (starting dose) |
| Weeks 5–8 | 5 mg |
| Weeks 9–12 | 7.5 mg |
| Weeks 13–16 | 10 mg |
| Weeks 17–20 | 12.5 mg |
| Week 21+ | 15 mg (if needed) |
Important: Not every patient climbs to the maximum dose. Your provider adjusts the schedule based on your response, your weight-loss progress, and any side effects. The 2.5 mg starting dose is a “warm-up” — it isn’t considered a long-term maintenance dose.
What’s the Starting Dose?
For nearly everyone, tirzepatide begins at 2.5 mg once weekly. This low dose isn’t expected to drive major weight loss on its own — its job is to let your digestive system get acquainted with the medication and to keep early nausea or stomach upset to a minimum. After at least four weeks, your provider reviews how you’re doing and decides whether to step up to 5 mg.
What’s the Maximum Dose?
The maximum recommended dose of tirzepatide is 15 mg once weekly. But “maximum” doesn’t mean “goal.” Many people reach their targets at a maintenance dose of 5 mg or 10 mg and never need to go higher. The right dose is the lowest one that gives you good results with side effects you can live with — and that’s a decision you and your provider make together, not a number to chase.
Compounded Tirzepatide Dosing
Some medical spas and clinics offer compounded tirzepatide, which a licensed pharmacy prepares rather than the brand manufacturer. Compounded tirzepatide is also dosed in milligrams, but because it comes in a vial drawn up with a syringe (rather than a pre-set pen), the same milligram dose can correspond to different injection volumes depending on the pharmacy’s concentration.
Here’s an illustrative example of how milligram doses map to typical injection volumes for a compounded product. The exact volume always depends on the specific formulation, so your label and your provider’s instructions are the final word.
| Dose (mg) | Typical Injection Volume* |
|---|---|
| 2.5 mg | 0.25 mL – 0.5 mL |
| 5 mg | 0.5 mL – 1 mL |
| 7.5 mg | 0.75 mL – 1.5 mL |
| 10 mg | 1 mL – 2 mL |
| 12.5 mg | 1.25 mL – 2.5 mL |
| 15 mg | 1.5 mL – 3 mL |
*Volumes vary by the pharmacy’s formulation strength. Always follow your provider’s instructions and check your prescription label for exact dosing.
Safety tip: Compounded tirzepatide dosing and instructions can differ from branded Zepbound®. Never switch between a compounded and a branded form — or change your dose — without clear, specific direction from your healthcare provider.
Tips for Staying on Track
A few simple habits make tirzepatide treatment smoother and more effective:
- Start low and go slow. Trust the titration. Rushing the dose up usually means more nausea, not faster results.
- Pick a consistent day. Same day each week keeps your levels steady; set a phone reminder if it helps.
- Don’t expect the top dose. Most people do well below 15 mg — the “sweet spot” is personal.
- Pair it with healthy habits. Medication works best alongside balanced eating, protein intake, and movement.
- Ask questions. If you’re unsure about your dose or your injection technique, reach out to our team — that’s what we’re here for.
How Tirzepatide Fits Into a Weight-Loss Plan
Tirzepatide is a powerful tool, but it works best as one part of a supervised, whole-person plan — not a standalone fix. Regular check-ins let your provider fine-tune your dose, track your progress, and make sure the medication is doing its job safely.
Frequently Asked Questions
Is tirzepatide the same as Zepbound and Mounjaro?
Tirzepatide is the active ingredient. Zepbound® is the brand approved specifically for weight management, while Mounjaro® is the brand approved for type 2 diabetes. Both contain tirzepatide.
How long does it take to see results?
Because the dose starts low and builds, meaningful weight loss usually becomes noticeable over the first couple of months and continues as you reach your maintenance dose. Everyone’s pace is different.
What if I miss a weekly dose?
Guidance depends on how many days have passed, so always follow your provider’s instructions and the directions on your prescription. Don’t double up to “catch up” without checking first.
