If you've seen "Tirzepatide Flex" on our website or your prescription, you may be wondering what it is and how it differs from other tirzepatide you may have heard about. Here's a plain-language explanation.

Compounded tirzepatide is not FDA-approved and is not the same as, or a generic version of, Zepbound or Mounjaro. Whether treatment is appropriate for you is decided by a clinical evaluation.

What is Tirzepatide Flex?

Tirzepatide Flex is the name we use at Nuvo for our compounded tirzepatide at a concentration of 15 mg/mL, in a 4 mL vial (60 mg in total). It's the tirzepatide I prescribe for Nuvo patients today, including patients who are just starting treatment.

"Flex" isn't a separate drug or a brand name. It's the same active ingredient as other compounded tirzepatide, prepared at a higher concentration.

How does Flex compare with 10 mg/mL tirzepatide?

Compounded tirzepatide is also made at 10 mg/mL. Flex, at 15 mg/mL, holds 50% more medication in each mL. That's the main reason I prescribe it: for many patients, it's the more cost-effective choice.

Because Flex is more concentrated, the same dose is a smaller amount in your syringe. If you've used a 10 mg/mL vial before, from Nuvo or anywhere else, the number of units you draw up will be different. Always follow the dosing instructions for the specific vial you have, and call or text me if you're ever unsure.

How long does a vial last?

At starting doses, a Flex vial lasts about 12 weeks. At higher doses, a vial is used faster. Most people start at a low dose and increase gradually, with at least four weeks at each step, which helps your body adjust and can reduce stomach side effects like nausea. Dose changes are decided together at your check-ins, and you should never change your dose on your own.

What does Tirzepatide Flex cost?

Tirzepatide Flex is $500 per fill, or two payments of $250. Each fill includes:

–The medication, shipped overnight cold to your door

–Syringes and supplies

–Ongoing follow-up with me

There's no monthly membership and no contract.

Important safety information

The most common side effects of tirzepatide are digestive, such as nausea, diarrhea, constipation and stomach discomfort, and they're often most noticeable after a dose increase. Tell me about any side effects at your check-ins. Get medical help right away for severe stomach pain, vomiting you can't stop, or signs of an allergic reaction.

If you miss a dose, call or text me rather than guessing.

Common questions

Is Tirzepatide Flex a different medication from tirzepatide?

No. It's the same active ingredient, compounded tirzepatide, prepared at 15 mg/mL.

Can new patients start on Tirzepatide Flex?

Yes. At Nuvo, Flex is the tirzepatide prescribed for new and current patients when tirzepatide is medically appropriate. Your dose is set by your provider after a clinical evaluation.

I used 10 mg/mL tirzepatide before. Will my syringe units change?

Yes. The same dose is fewer units at 15 mg/mL than at 10 mg/mL. Follow the instructions that come with your vial, and contact your provider with any questions before injecting.
