Is Zepbound a Semaglutide? Brand Names vs Molecules

No, Zepbound is not a semaglutide. It is tirzepatide, the same molecule as Mounjaro. Wegovy and Ozempic are both semaglutide, and both now come as a daily tablet as well as a weekly pen. Rybelsus is semaglutide too. The nine brand names below cover five molecules, and knowing which is which is the difference between reading a price correctly and being sold something on a trial result that was never about it.

This is not pedantry. Almost every confusing thing in this market comes back to the gap between a brand and the substance inside it: why two drugs cost the same, why your insurer covers one and not the other, why a compounded seller quotes a number from a trial they were not in.

The whole map, on one table

Every molecule with both a diabetes label and a weight label gets a separate brand name for each. The drug is the same and so is the factory. The box is different, and so, frequently, are the price and the coverage.

Where this costs you money

1. Coverage follows the label, not the molecule. A plan that excludes weight-management drugs may still cover the diabetes-labeled twin when the diagnosis is diabetes. Which name is on the prescription can decide whether it is paid for.
2. Manufacturer cash ladders differ by brand. In October 2026 Novo charged the same $349 a month for Wegovy and Ozempic pens at most doses, but $399 for Wegovy HD and $499 for Ozempic 2 mg.^[5][6] Lilly charged $299 to $699 for the Zepbound KwikPen depending on dose and refill timing, and $499 for Mounjaro at every dose.^[7][8] Same molecule, different ladder, so at a high dose the diabetes brand can be the cheaper one.
3. Trial results attach to a dose, not a name. Ozempic tops out at 2 mg for diabetes. Wegovy’s usual maintenance dose is 2.4 mg for weight, and the label now allows 7.2 mg for some patients.^[1] Quoting weight-loss figures from one at the doses of the other overstates what you should expect.
4. Compounded sellers sell the molecule. Nobody is selling you compounded Zepbound. They are selling compounded tirzepatide, a different product with different oversight, and they often quote Zepbound’s trial number next to it.

So when a listing says compounded semaglutide or tirzepatide, read it as the molecule from a pharmacy, not as the brand. Mevo Health, HealthRX and Blue Sky MD all sell both molecules that way; Blue Sky MD sells them only inside its full medical weight-loss program, with coaching. Loozy publishes a price for compounded semaglutide only, with tirzepatide offered inside its intake.

One seller can sell both the molecule and the brand, so check which line of the menu you are reading. Tuyo Health sells compounded semaglutide and tirzepatide with no membership fee, and separately sells brand Wegovy and Zepbound on plans that do carry a membership, with its team handling the insurance paperwork. Found is set up the other way round: its compounded plans bundle the medication and membership at one price per dose, while brand-name drugs are billed separately from the membership.

Which of these is a pill?

Four brand names, two molecules, and neither is tirzepatide. Rybelsus and Ozempic tablets are oral semaglutide for type 2 diabetes, sold under one label but in different strengths, and the label says they are not substitutable milligram for milligram.^[4] In the US, Ozempic tablets are replacing Rybelsus. The Wegovy pill is oral semaglutide for weight management, approved in December 2025, with 25 mg daily as the maintenance dose.^[1] All three need a strict fasting window because a peptide barely survives the gut without help. Foundayo is orforglipron, approved in April 2026 for weight management. It is a non-peptide small molecule, which is why it does not need the same food rules.

There is no oral tirzepatide. If a seller offers you “tirzepatide tablets” or a sublingual version, they are offering a compounded preparation with no approved counterpart and therefore no bioavailability standard to measure it against. Nobody can tell you what fraction of the dose reaches your bloodstream. And whatever you are offered, it is not a patch, because a peptide that size does not cross skin.

Several sellers in our register list exactly that. HealthSource sells compounded tirzepatide as an oral sublingual, and YourHealthRx sells compounded semaglutide and tirzepatide as daily dissolving tablets. He & She MD lists oral versions of both beside access to brand Ozempic, Zepbound and Wegovy, and VirtualCare2Go, a Texas-only practice, sells semaglutide tablets in a monthly package. Whatever the checkout calls it, ask which of the two you are buying: an approved tablet or a compounded preparation.

Things sold beside these that are not GLP-1s at all

Peptide sellers frequently list these next to GLP-1s, which invites the assumption that they belong to the same family. They do not. For the prescription drugs most often mistaken for one, see which drugs are GLP-1s.

• Tesamorelin (EGRIFTA) is a growth hormone-releasing factor analog, approved for HIV-associated lipodystrophy, and its label says it is not indicated for weight loss management.
• BPC-157 is not approved for anything, and it is not on the list a compounding pharmacy may lawfully use. Under an interim policy dated October 28, 2026, HHS does not plan to pursue 503A pharmacies that compound it under strict conditions, which is not an approval.^[10]
• Retatrutide is a real Lilly drug candidate whose phase 3 trials have begun to report. It is not approved anywhere, and Lilly plans to apply in the first quarter of 2027, whatever is being sold under the name now.
• Sermorelin, ipamorelin and AOD-9604 are growth-hormone-axis peptides, not incretin drugs. They work by a different mechanism and rest on different evidence, and none of them is approved for weight loss; AOD-9604 was tested for obesity and failed.
