Compounded tirzepatide is a made-to-order version of the drug tirzepatide, prepared by a state-licensed 503A compounding pharmacy for one patient at a time. It is not FDA approved, and it is not the same product as Zepbound or Mounjaro. You get it with a prescription from a licensed clinician, usually through telehealth, and it ships cold to your door. At FormBlends the first month is $149 and later months are $239, at any dose. Start with our tirzepatide guide if you are new to the drug.
Key takeaways
- Compounding means a licensed pharmacist prepares a drug for a specific patient from a prescription, as the FDA explains in its compounding questions and answers.
- Compounded tirzepatide is not FDA approved and is not interchangeable with Zepbound or Mounjaro; a licensed provider decides whether it is appropriate for you.
- Tirzepatide itself was studied in SURMOUNT-1, where the 15 mg dose produced a mean weight change of -20.9% at 72 weeks compared with -3.1% for placebo.
- FormBlends compounded tirzepatide costs $149 for the first month, then $239 a month, or $214 a month with Subscribe & Save. The price does not change with dose.
- Zepbound vials through LillyDirect self-pay run $299 to $699 a month depending on the dose, and some commercially insured people pay as little as $25 a month with the savings card.
What "tirzepatide compound" means
Tirzepatide is the active ingredient in two branded drugs made by Eli Lilly: Mounjaro, approved for type 2 diabetes in May 2022, and Zepbound, approved for chronic weight management in November 2023 and for obstructive sleep apnea in adults with obesity in December 2024. Both are once-weekly injections.
A "compound" is different. The FDA describes compounding as combining, mixing or altering ingredients to create a medication tailored to the needs of an individual patient. A compounding pharmacy buys tirzepatide as a raw ingredient, dissolves it in a sterile solution, and fills it into a vial labeled for one named patient. That vial is compounded tirzepatide.
Two facts follow from that. First, the FDA does not review compounded drugs for safety, effectiveness or quality before they are sold. Second, no compounded tirzepatide product has been through the SURMOUNT trials. The trial numbers on this page describe the branded, FDA-approved product. They are the reason people are interested in the molecule, not proof that a given vial performs the same way.

Compounding is legal when it is done by a licensed pharmacist or physician under a valid prescription. Federal law recognizes two kinds of compounders. The kind most telehealth programs use is the 503A pharmacy, which is licensed and inspected by its state board of pharmacy and must compound for identified patients.
The FDA has published a page on its concerns with unapproved GLP-1 drugs used for weight loss. It warns that compounded and other unapproved versions are not reviewed by the agency, that dosing errors have been reported when people draw up doses from vials, and that products sold without a prescription or from unlicensed sources may not contain what the label says. Those warnings are the main reasons to use a licensed program, get a prescription from a real clinician, and learn how to measure a dose before you start.

What the trials say about tirzepatide
SURMOUNT-1 enrolled 2,539 adults with obesity or overweight who did not have diabetes and followed them for 72 weeks. The results below are for the branded injectable used in the trial.
| Group (72 weeks) | Mean weight change | Lost at least 5% | Lost at least 20% |
|---|---|---|---|
| Placebo | -3.1% | 35% | 3% |
| Tirzepatide 5 mg | -15.0% | 85% | Not reported in the summary |
| Tirzepatide 10 mg | -19.5% | 89% | 50% |
| Tirzepatide 15 mg | -20.9% | 91% | 57% |

The most common adverse events in the trial were gastrointestinal, mostly mild to moderate, and mostly during dose escalation. Nausea was reported by 24.6% of the 5 mg group, 33.3% of the 10 mg group and 31.0% of the 15 mg group, against 9.5% on placebo. Those events clustered during dose escalation, which is one reason the label starts everyone at 2.5 mg.

How to get compounded tirzepatide online
Here is how the FormBlends program works, step by step.
- Online assessment. You answer health questions at /start. Availability for your address is confirmed during the assessment, before any charge.
- Clinician review. An independent, state-licensed clinician (MD, DO, NP or PA) of Recess MD LLC, a medical group separate from Form Blends LLC, reviews your answers and decides whether tirzepatide is appropriate. If not, the charge is refunded.
- Compounding. The prescription goes to a state-licensed 503A compounding pharmacy. FormBlends works with Greenwich RX in Texas, The DrugStore on East State in Ohio, and Chemistry Rx in Pennsylvania.
- Cold-chain shipping. The vial ships refrigerated to your door with injection supplies included. Dispensed medication is not returnable.
- Dosing. The clinician sets your dose. The labeled schedule for the branded product starts at 2.5 mg once weekly for 4 weeks, then increases in 2.5 mg steps after at least 4 weeks on each dose, up to 15 mg. Never change your dose on your own.
FormBlends has dispensed to 36 states, based on the last 165 shipped orders as of September 5, 2026.
Where to buy tirzepatide safely: a short checklist
- A licensed clinician must review your health history and write the prescription. You can verify a clinician on your state medical or nursing board website.
- The pharmacy should be a state-licensed 503A compounding pharmacy that you can look up on its state board of pharmacy site.
- The vial label should show your name, the drug, the concentration (for example 10 mg/mL), and a beyond-use date.
- "Tirzepatide powder" or "research peptide" vials sold without a prescription are not compounded medication. The FDA's page on unapproved GLP-1 drugs explains why those sources are a concern. Our gray market tirzepatide page goes deeper.
Drawing a dose from a compounded vial
Compounded tirzepatide usually comes in a multi-dose vial. You draw the dose with a U-100 insulin syringe, where 1 mL equals 100 units. The concentration on your vial label controls the math, so always confirm it with the pharmacy. At 10 mg/mL as an example, 2.5 mg is 0.25 mL or 25 units, 5 mg is 50 units, 7.5 mg is 75 units, 10 mg is 100 units, 12.5 mg is 125 units and 15 mg is 150 units. A 5 mg/mL vial doubles those unit counts; a 20 mg/mL vial halves them. Inject under the skin of the abdomen, thigh or upper arm, and rotate sites.
What this means for compounded tirzepatide
Every dosing rule, warning and side effect on the branded label applies to the molecule, so read them before you start. The boxed warning covers thyroid C-cell tumors seen in rats; the drug is contraindicated if you or a family member has had medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2. Tell your prescriber about pancreatitis, gallbladder disease, kidney problems, diabetes medicines, oral contraceptives, or plans for pregnancy. Compounded tirzepatide is not FDA approved, and a licensed provider decides whether it is appropriate for you. Ready to find out? Begin the online assessment.
Frequently Asked Questions
How much does compounded tirzepatide cost per month?
At FormBlends, compounded tirzepatide is $149 for the first month and $239 a month after that, or $214 a month with Subscribe & Save. The price is the same at every dose. Shipping and injection supplies are included; lab work is not.
Where can I get compounded tirzepatide?
Through a telehealth program or a local clinician who works with a state-licensed 503A compounding pharmacy. At FormBlends you complete an online assessment, a Recess MD LLC clinician reviews it, and if prescribed, the pharmacy ships the medication cold to your door. Availability for your address is confirmed before any charge.
What is the cheapest way to get tirzepatide?
If you have commercial insurance that covers Zepbound, the savings card can bring it to as little as $25 a month. Without coverage, Zepbound vials through LillyDirect start at $299 a month for 2.5 mg and reach $699 at 10 mg and above. FormBlends compounded tirzepatide is $239 a month at any dose, which is cheaper than Zepbound self-pay at every dose above 2.5 mg, but it is not FDA approved.
Can I buy tirzepatide powder or a compound online without a prescription?
Not legally as a medication. Compounded tirzepatide always requires a prescription from a licensed clinician. Vials sold as "research" powder are not compounded drugs, are not tested for you, and are flagged by the FDA as a source of concern.
Is compounded tirzepatide approved by the FDA?
No. Compounded tirzepatide is not FDA approved and is not interchangeable with Zepbound or Mounjaro. The FDA does not check compounded drugs for safety, effectiveness or quality before they are sold, which is why the pharmacy's state license and the clinician's review matter.
How much weight can you lose on tirzepatide?
In SURMOUNT-1, the branded injectable produced a mean weight change of -15.0% at 5 mg, -19.5% at 10 mg and -20.9% at 15 mg after 72 weeks, versus -3.1% on placebo. No trial has tested a compounded product, so those numbers describe the molecule under trial conditions, not a guarantee for any vial.
