People search for a tirzepatide dosage chart because the dose is not one number. It climbs in steps. This guide lays out the standard clinical step-up, explains why it rises slowly, and answers the common questions. It reports known information for education. It is not a dose plan, and Genix does not sell tirzepatide.
The quick answer
Tirzepatide is given once a week, and the dose steps up over time. The standard clinical schedule starts at 2.5 mg, then rises to 5, 7.5, 10, 12.5, and up to 15 mg, with about four weeks at each step. The slow climb keeps stomach side effects milder. This is the known schedule, not a plan for any person.
The tirzepatide dosage chart
Here is the standard step-up, laid out simply. The starting dose is low on purpose. It is not meant to be the working dose. It is a gentle start so the body can adjust.
| Step | Weekly dose | Typical time at step | Purpose |
|---|---|---|---|
| 1 | 2.5 mg | 4 weeks | Gentle start, adjust |
| 2 | 5 mg | 4 weeks | First working step |
| 3 | 7.5 mg | 4 weeks | Step up if needed |
| 4 | 10 mg | 4 weeks | Stronger step |
| 5 | 12.5 mg | 4 weeks | Higher step |
| 6 | 15 mg | Maintenance | Highest standard dose |
Why does the dose step up?
The main reason is comfort. Like all GLP-1 style compounds, tirzepatide can upset the stomach, most at the start and at each step up. A slow climb gives the body time to adjust, which keeps nausea milder and helps people stay the course.
- It lowers nausea and stomach upset.
- It helps the body adjust to each new level.
- It reduces the chance of stopping early.
- The starting dose is not the working dose.
What each step does
The first step at 2.5 mg is mostly about adjusting, not results. Real appetite change tends to show from 5 mg up. Many people find a level that works for them somewhere in the middle of the chart, without needing the top dose. Higher is not always better, and everyone is different.
How is a tirzepatide dose given?
In clinical use, tirzepatide is a once-weekly injection under the skin, usually in the belly, thigh, or upper arm, on the same day each week. It comes as a prepared pen or vial. This is a prescription process managed by a clinician, which is another reason this guide is education only.
What if a dose is missed?
The general clinical guidance is that a missed weekly dose can often be taken within a few days, then the normal weekly schedule resumes. If it is close to the next dose, one is usually skipped rather than doubled. This is a question for the prescribing clinician, not a blog.
Can you change your injection day?
In clinical use, the weekly day can usually be moved as long as there are at least a few days between doses. People sometimes shift it to fit their week. Any change should be checked with the prescriber, since spacing matters.
How do you know if a dose is too high?
Signs that a step may be too strong are usually stomach-related, like strong nausea, vomiting, or being unable to eat normally. Feeling wiped out or lightheaded can also be a flag. The usual clinical answer is to slow the step-up, not push through. Again, this is a doctor question.
- Strong or lasting nausea and vomiting.
- Not being able to eat normally.
- Feeling very tired or lightheaded.
- The usual fix is a slower step-up, guided by a clinician.
How this compares to retatrutide
Tirzepatide hits two targets. Retatrutide, the newer research peptide, hits three, adding a glucagon signal that raises energy burn. Both use a slow step-up. In studies, retatrutide moved more weight. For the full breakdown, see our guide to semaglutide vs tirzepatide and to retatrutide dosing.
Why purity matters for any dosing
Any dose chart only means something if the vial holds what the label says. For research peptides, that is why a certificate of analysis matters. A Genix batch COA shows HPLC purity of at least 99%, LC-MS identity, and a lot number that matches your vial.

Tirzepatide is given once a week, stepping up from 2.5 mg to 5, 7.5, 10, 12.5, and up to 15 mg, with about four weeks at each step. The low start lets the body adjust. This reports the standard clinical schedule for education, not as a dose plan.
What if I miss a dose of tirzepatide?
The general clinical guidance is that a missed weekly dose can often be taken within a few days, then the normal weekly schedule resumes. If it is close to the next dose, one is usually skipped rather than doubled. This is a question for the prescribing clinician.
Can I change my tirzepatide injection day?
In clinical use the weekly day can usually be moved, as long as there are at least a few days between doses. People sometimes shift it to fit their week. Any change should be checked with the prescriber, since spacing matters.
How do I know if my tirzepatide dose is too high?
Signs a step may be too strong are usually stomach-related: strong nausea, vomiting, or being unable to eat normally. Feeling wiped out or lightheaded can also flag it. The usual clinical answer is to slow the step-up, not push through. Ask a doctor.
Takeaway
The tirzepatide dosage chart is a slow climb, from 2.5 mg up to 15 mg once a week, about four weeks per step. The low start is on purpose, to keep side effects mild. Higher is not always better. This guide reports the known schedule for education, not as a dose plan. Genix does not sell tirzepatide, and this is not medical advice.
