Yes, you can get tirzepatide online, but only with a prescription, and what arrives depends on which version the prescriber writes for. Two are Eli Lilly brands with an FDA label: Zepbound for weight loss and sleep apnea, and Mounjaro for type 2 diabetes. The third is compounded by a pharmacy and has no FDA approval; on our board it starts at $71 a month.
The active drug is the same molecule in each case. What differs is the label, who makes it, the legal footing and the monthly bill. This page sorts those out, then points you to the live ranking.
The three versions of tirzepatide sold online
| Version | Who makes it | FDA approved? | Labelled for | Cash price |
|---|---|---|---|---|
| Zepbound | Eli Lilly | Yes | Weight loss and sleep apnea9 | See the Zepbound programs below, or Zepbound cost without insurance |
| Mounjaro | Eli Lilly | Yes | Type 2 diabetes | See Mounjaro cost |
| Compounded tirzepatide injection | A compounding pharmacy | No1 | No label of its own | $71 to $299 a month on our board |
The compounded figures are the partner programs on our board today, all-in with any verified fee. For Zepbound, the label says it is for adults "to reduce excess body weight and maintain weight reduction long term" with obesity, or with overweight plus at least one weight-related condition, and "to treat moderate to severe obstructive sleep apnea (OSA) in adults with obesity".9 It also says combining it with "other tirzepatide-containing products or with any GLP-1 receptor agonist is not recommended", so do not stack versions.9
How the online prescription works
- You fill in a health history. Weight, height, conditions, medicines and pregnancy plans. A program that skips this is not one to use.
- A licensed clinician reviews it. They decide whether tirzepatide is appropriate and which version. Some programs do this by form and message, others by video.
- A pharmacy fills the prescription. For Zepbound, that is a pharmacy dispensing the brand. For a compounded version, a state-licensed compounding pharmacy makes it for you.
- It ships to your door. You inject it yourself once a week. Your prescriber explains the starting dose and how it steps up.
Our guide to how to get Zepbound covers the brand route, and how telehealth weight loss programs work covers the visit and follow-up. If your plan may pay, start with how to get a GLP-1 covered.
What the law now allows compounders to make
Compounded tirzepatide spread while the brand was in short supply. That period is over.
| Rule | What FDA says | What it means for a buyer |
|---|---|---|
| Shortage | FDA determined "the tirzepatide injection shortage is resolved"6 | The shortage-era free hand is gone |
| Outsourcing facilities (503B) | On 30 April 2026 FDA proposed to exclude tirzepatide from the 503B bulks list, "finding no clinical need"7 | Large-batch compounding from bulk tirzepatide has no route back while that stands |
| Pharmacies (503A) | A drug "compounded for an individual patient based on receipt of a prescription", not "essentially copies of a commercially available drug product"5 | Your compounded vial should be made for your prescription, not stock |
None of this makes it illegal for you to fill a compounded prescription. It does mean the program and its pharmacy must be able to show why your version differs from the brand. FDA's own line is that compounded drugs "should only be used in patients whose medical needs cannot be met by an FDA-approved drug".1 More detail is in our compounded tirzepatide guide.
Five checks before you buy tirzepatide online
- A prescription is required. Both Lilly brands are prescription medicines, and a compounding pharmacy may only make the drug "for an individual patient based on receipt of a prescription".5 A site that sells it with no health review is a red flag.
- A real, named US pharmacy fills it. FDA is "aware of fraudulent compounded semaglutide and tirzepatide" where "the compounding pharmacies identified on the labels of the products do not exist."2 Look up the pharmacy name on your state board's licence lookup; our seller checks show how.
- You understand your dose and how to measure it. FDA has logged reports, some needing hospital care, from "patients measuring and self-administering incorrect doses".3 Ask for the dose in plain terms, and for the pharmacy or prescriber to show you how to draw it, before your first injection.
- It is not sold as Zepbound, Mounjaro or "generic". In March 2026 FDA sent warning letters to 30 telehealth companies; the main issues were "claims implying sameness with FDA-approved products". FDA adds that compounded drugs "are also not the same as generic drugs, which are FDA-approved."8
- Someone answers after delivery. FDA points patients with dosing questions back to their health care provider or the compounder.3 Ask before paying who that is and how quickly they reply.
Adverse events happen with any version of the drug. FDA counted "more than 730 reports of adverse events associated with compounded tirzepatide" by 31 May 2026, and pharmacies outside the outsourcing system do not have to report, so the true number is likely higher.4 What compounding takes away is FDA's pre-market review: unapproved versions "do not undergo FDA’s review for safety, effectiveness and quality before they are marketed."1
Tirzepatide programs on our board, cheapest first
This is the live ranking for compounded tirzepatide: partner programs only, ordered by today's all-in monthly price with any verified fee added. Nothing in the order is paid for; how programs are scored is on our methodology page.
If you want the brand, Zepbound programs are ranked separately, because a Lilly-made pen and a compounded vial are not the same purchase:
