Tirzepatide results timeline: what to expect, month by month

Medically reviewed by the NexLife clinical team, led by Adam Kennah, MD (NPI 1144260043) · Updated

Tirzepatide starts at 2.5 mg and steps up every 4 weeks or more, so the first months are about adjusting. In the 72-week SURMOUNT-1 trial of Zepbound, average weight loss was 15.0% to 20.9% depending on dose, and 9 in 10 people on 15 mg lost at least 5%. People who stopped after 36 weeks regained 14.0% over the next year. At NexLife, compounded tirzepatide is $139 a month on a 12-month plan, or $169 month to month, the same at every dose, matched if you pay less†.

The timeline

Tirzepatide results timeline, month by month

From the Zepbound prescribing information. Your own pace depends on your dose, your body and your habits.

  1. Getting started. 2.5 mg a week, a starting dose that isn’t meant for the long term. It takes about 4 weeks for blood levels to settle on a dose. Stomach side effects are most likely while the dose is going up.

  2. Stepping up. The dose can rise by 2.5 mg after at least 4 weeks at each step. The earliest 15 mg can start is week 21. Your provider sets the pace; some people stay longer at a dose.

  3. At your maintenance dose. In Study 1, people spent at least 52 weeks on their maintenance dose (5, 10 or 15 mg) before results were measured at week 72.

  4. The trial endpoint. In Study 1, average loss was 15.0% on 5 mg, 19.5% on 10 mg and 20.9% on 15 mg, versus 3.1% on placebo.

  5. What Study 4 found. People who took it for 36 weeks and were then switched to placebo regained 14.0% of their weight over the next 52 weeks; those who kept taking it lost another 5.5%.

What changes the pace

Four things that shaped results in the trials

  • Your dose

    Higher maintenance doses led to more weight loss on average: 15.0% on 5 mg vs 20.9% on 15 mg.

  • Type 2 diabetes

    People with type 2 diabetes lost less on average: 12.8% on 10 mg and 14.7% on 15 mg in Study 2.

  • Staying on it

    Stopping after 36 weeks led to regaining 14.0% over the next year in Study 4. Continuing led to more loss.

  • Your habits

    Every trial group had diet and activity advice. Protein and strength training help protect muscle as weight comes off.

After 36 weeks on tirzepatide (20.9% lost on average), 670 people were randomly assigned to keep taking it or switch to placebo for 52 more weeks; people who stopped earlier weren’t included. Zepbound label, Table 6.

A price that holds while you do.

$139 a month on a 12-month plan, or $169 month to month, at every dose, so staying on track doesn’t get more expensive as your dose rises.

Results questions

How fast does tirzepatide work?

Blood levels settle after about 4 weeks on a dose, and doses step up every 4 weeks or more. In the trials, weight loss built over months; results were measured at 72 weeks.

How much weight can I lose on tirzepatide in a month?

The trials reported results at 36 and 72 weeks, not month by month. Averaged over 72 weeks, the 15 mg group’s 20.9% works out to about 0.3% of body weight a week; real loss isn’t that even.

What results can I expect after 3 months?

At 3 months you’re typically still stepping up the dose. The label reports results at 36 and 72 weeks; your provider can tell you what your progress means.

How many people lose 20% on tirzepatide?

In Study 1, 56.7% of people on 15 mg lost at least 20% of their weight by week 72, versus 3.1% on placebo.

What happens if I stop taking tirzepatide?

In Study 4, people switched to placebo after 36 weeks regained 14.0% of their weight over the next year on average, while people who continued lost another 5.5%.

Will compounded tirzepatide give the same results?

Compounded tirzepatide hasn’t been studied in clinical trials and isn’t FDA-approved. These results come from trials of Zepbound.

Important safety information

Compounded tirzepatide and semaglutide are not FDA-approved, and the FDA hasn’t reviewed them for safety, effectiveness or quality. A provider prescribes them only when they offer a significant difference for you compared with an FDA-approved product. Both medicines may cause thyroid tumors, including cancer: don’t use either if you or a family member has had medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN 2).

Read the full safety information

In studies with rodents, both medicines caused thyroid tumors; it isn’t known whether they cause them in people. Tell your provider if you notice a lump or swelling in your neck, hoarseness, trouble swallowing or shortness of breath. Serious side effects can include inflammation of the pancreas (pancreatitis), gallbladder problems, low blood sugar (especially with insulin or sulfonylureas), kidney problems from dehydration, severe stomach problems, serious allergic reactions, vision changes in people with type 2 diabetes, and a faster heart rate. Tell your care team before any surgery or procedure that uses anesthesia or deep sedation. Don’t combine either medicine with other GLP-1 medicines.

Tirzepatide can make birth control pills less effective: switch to a non-oral method, or add a barrier method such as condoms, for 4 weeks after you start and for 4 weeks after each dose increase. Both medicines may harm an unborn baby. Semaglutide should be stopped at least 2 months before a planned pregnancy. Tell your provider right away if you’re pregnant, planning to be, or breastfeeding.

This is a summary, not the complete safety information. Read the full Prescribing Information for FDA-approved tirzepatide (Zepbound) and semaglutide (Wegovy), and talk with your provider. You can report side effects to the FDA at 1-800-FDA-1088 or fda.gov/medwatch.
