How it works

Stubborn weight is often appetite signals and insulin that stopped working in your favor. Tirzepatide copies two gut hormones, GIP and GLP-1. Together they slow how fast your stomach empties, quiet hunger and help your body respond to insulin. Our version adds glycine, to help reduce muscle loss during weight loss, and vitamin B12, to help reduce fatigue and maintain vitamin levels. Those additions were not tested in the trials.

What to expect

  1. 01

    Weeks 1 to 4

    You start at the lowest dose. Hunger and portions often shrink first; the scale can lag.

  2. 02

    Months 2 to 5

    Your clinician raises the dose in small steps, at least four weeks apart. Nausea is most likely right after a step, and smaller, slower meals help.

  3. 03

    Months 5 to 18

    Weight keeps coming down. In the main trial the dose stepped up over 20 weeks and the average kept falling through week 72.

  4. 04

    After that

    Weight tends to return if treatment stops, so you and your clinician plan the long game together.

What makes it work better

Three things you can do alongside your treatment.

  1. Two people stretching outdoors
    01

    Protect your muscle

    Bigger weight loss means more lean mass at stake. Protein at every meal and strength training two or more days a week help protect it, and muscle also helps clear blood sugar.

  2. A woman with a bag walking up old town stairs
    02

    Break up your sitting

    Long stretches of sitting go with a larger waist and more abdominal fat. Stand or walk every 30 minutes or so, and aim for 150 to 300 minutes of moderate movement a week.

  3. Woman unpacking fresh groceries in her kitchen
    03

    Check the markers behind the scale

    Stubborn weight often traces back to insulin resistance. Our clinicians look at HbA1c (optimal 4.6 to 5.3%), triglycerides (optimal 50 to 80 mg/dL) and vitamin B12 (optimal 545 to 1100 pg/mL).

Separate trials of the FDA-approved brands, not a head-to-head comparison. Compounded versions are not FDA-approved. Your clinician helps you choose.

Before you start

  • Usually prescribed at a BMI of 30 or more, or 27 or more with a weight-related condition. A clinician decides.
  • Not for anyone with a personal or family history of medullary thyroid carcinoma or MEN 2, or who is pregnant.
  • Take birth control pills? The FDA-approved tirzepatide label says to switch to a non-pill method or add a barrier method for 4 weeks after you start and after each dose increase.
  • On hormone therapy, or in perimenopause or menopause? Tell your clinician so they see the full picture.

How to take it

Inject under the skin once a week, on the same day each week. The first four weeks use 2.5 mg (25 units on the syringe). Your clinician then raises the dose in 2.5 mg steps, at least four weeks apart, to the lowest dose that works for you, and does not step up while side effects are active.

Side effects and safety

Tirzepatide caused thyroid C-cell tumors in rats. Whether that happens in people is not known.

Tell your care team straight away if you feel a lump or swelling in your neck, your voice goes hoarse or swallowing becomes hard, you get severe stomach pain that will not stop, you cannot keep up with vomiting or diarrhea, you get pain in your upper right belly or your eyes turn yellow, or you get a rash with swelling of the face or lips or trouble breathing.

Common side effects

  • nausea
  • diarrhea
  • vomiting
  • constipation
  • abdominal pain
  • indigestion
  • injection site reactions
  • fatigue
  • hair loss

Rare but serious

  • acute pancreatitis
  • gallbladder disease
  • kidney injury from fluid loss
  • low blood sugar
  • worsening diabetic eye disease
  • food left in the stomach during anesthesia

Do not take this if you or a family member has had medullary thyroid carcinoma, you have Multiple Endocrine Neoplasia syndrome type 2, or you have reacted badly to tirzepatide before.

This is not a complete list of side effects. Message your care team about any symptom that worries you. What we dispense is a compounded preparation made by a licensed US pharmacy. Compounded medications are not approved by the FDA for safety, efficacy or quality.

Common questions

A white man in his early 50s with a salt-and-pepper beard reading a message from his care team
Is compounded tirzepatide FDA-approved?+

No. A licensed US pharmacy makes it for you, and it is not FDA-approved. The FDA does not review compounded drugs for safety, effectiveness or quality before they are dispensed.

Tirzepatide or semaglutide: which is right for me?+

In separate trials, tirzepatide's average weight loss was higher. Your clinician weighs your history, side effects and goals.

How common is nausea?+

In trials of FDA-approved tirzepatide, 25-33% had nausea versus 10% on placebo, mostly while the dose was rising. Smaller meals help.

Will I lose muscle?+

Some lean mass is lost with any weight loss. Protein and strength training help protect it.

Does it affect birth control pills?+

Tirzepatide can make birth control pills less reliable after starting and after each dose increase. Ask your clinician about a backup method.

What happens if I stop?+

Appetite usually returns and weight may come back. Plan the next step with your clinician.
