Zepbound vs. Tirzepatide: What You're Actually Choosing Between

Zepbound vs. compounded tirzepatide: which costs less?

Compounded tirzepatide is cheaper to start, but the gap is smaller than it used to be. Lilly's own self-pay Zepbound now costs about $100 to $150 more a month than the cheapest compounded options at the starting dose.

At higher doses, it depends on the seller. Lilly's price stops rising at 7.5 mg. Mochi stays well below it at every dose. Willow's top doses cost more than Zepbound. Here is what each option is and who it suits.

• LillyDirect, brand-name Zepbound. This is the real Lilly drug, as a vial or a prefilled KwikPen pen. The price rises over the first doses, then stays at about $450 from 7.5 mg up. To keep that price, refill within 45 days. Miss the window and the regular price applies, up to about $700 a month. The KwikPen is also sold at Lilly's price at retail pharmacies. Best for anyone who wants FDA-approved quality without insurance.
• Mochi Health, compounded. It has the lowest starting price we found, about $170 a month, membership included. The medicine price rises with the dose, up to about $280 all-in. Your first month costs about $90, because the membership is free that month where the offer applies. Paying the membership a year ahead lowers it to about $50 a month. Best for a low entry price, if you're fine with a monthly membership.
• Curex, compounded. Month to month, the tablet costs about $250 and the shot about $300 at the starting dose. Both cost about $100 more at higher doses. A year paid upfront brings the lowest dose to about $200 a month. The visit and shipping are included, with no membership. Best for one all-in price with a choice of shot or tablet.
• Henry Meds, compounded. It sells tirzepatide only as a dissolving tablet. The tablet costs about $350 a month, billed every 3 months. Paying the 3 months up front brings it to about $295 a month. Best for people who want a pill and accept the open legal questions below.
• Willow, compounded. The shot costs about $400 a month at lower doses and up to about $550 at the top. It also sells a dissolving tablet, from about $400. Willow serves only 36 states. Best if you live in one of them and want a choice of shot or tablet.
• Medicare GLP-1 Bridge. Part D is the drug coverage part of Medicare. If you have it and qualify, the Zepbound KwikPen costs $50 a month. The program runs from July 1, 2026 to December 31, 2027. Compounded tirzepatide isn't part of it.
• Retail pharmacy with GoodRx. A GoodRx coupon brings Zepbound to about $995 to $1,050 a month. That is barely below list price. Ask for Lilly's self-pay price instead, which is far lower.

Every compounded seller is compared in compounded tirzepatide, and every price route in tirzepatide cost. With no insurance at all, tirzepatide without insurance lays out each path. Cheapest tirzepatide ranks the lowest prices we track.

Is Zepbound the same thing as tirzepatide?

Yes. Tirzepatide is the active drug. Zepbound is Eli Lilly's brand name for it, FDA-approved in 2023 for long-term weight management. In 2024, the FDA also approved it for moderate to severe sleep apnea in adults with obesity.

The same drug is also sold as Mounjaro, approved for type 2 diabetes. It's the same active ingredient with a different use and different packaging. So there's no medical tradeoff between "Zepbound" and "tirzepatide." They aren't two different drugs.

What most people searching this really want to know is Zepbound versus compounded tirzepatide. That means Lilly's approved shot against a pharmacy-made version of the same ingredient, sold through cash-pay telehealth.

What separates Zepbound from compounded tirzepatide?

Zepbound went through FDA review as a finished drug. The agency checked Lilly's manufacturing, sterility controls and dose-to-dose consistency before it reached pharmacies.

Compounded tirzepatide is made by a licensed pharmacy under state pharmacy law, from tirzepatide the pharmacy buys itself. It hasn't gone through that finished-product review. The pharmacy doesn't have to prove the same consistency or sterility testing Lilly's plants do.

Some compounded versions also add ingredients Zepbound doesn't contain, such as vitamin B12, glycine or L-carnitine. In an open letter, Lilly says its tests of tirzepatide mixed with B12 found a new impurity from a reaction between the two. It also reports bacterial contamination in other compounded tirzepatide. Some samples had high levels of endotoxins, toxins left behind by bacteria. Lilly has an obvious business stake here. Still, these add-ins haven't been studied with tirzepatide the way the drug itself has.

Is compounded tirzepatide still legal and safe right now?

It's legal, but on narrower ground than during the 2022 to 2024 shortage. The FDA declared the tirzepatide shortage over in December 2024. Large-scale compounding by outsourcing facilities, called 503B pharmacies, had to stop by March 2025.

What remains is the 503A route. A licensed pharmacy can compound tirzepatide for one named patient, when a clinician documents why the approved drug won't work for that person. Under FDA rules, cost alone isn't that kind of reason, even though cost is why most people look.

On April 30, 2026, the FDA proposed not to add tirzepatide, semaglutide and liraglutide to the 503B bulk drug list. That list says which ingredients outsourcing facilities may use. The comment period, extended through July 30, 2026, has closed. Even a final decision wouldn't change the 503A rules.

Eli Lilly also sued several telehealth sellers in April 2025, including Mochi Health, Henry Meds and Willow. The suits say these sellers marketed compounded tirzepatide in misleading ways, for example as "personalized" medicine. Lilly's complaint says Henry sold a tirzepatide pill the FDA has never approved.

The cases have gone different ways. A federal judge dismissed the Willow case in February 2026, and Lilly has appealed. The Henry Meds case is still open, in the evidence-gathering stage. The Mochi case is also open, with a jury trial set for January 2028.

Does Zepbound come as a pill? Tirzepatide tablets vs. injections

No. Zepbound is a shot only, sold as a single-dose vial you draw with a syringe or as a prefilled KwikPen. There's no FDA-approved tirzepatide pill.

That's partly chemistry. Tirzepatide is a peptide, a small protein, and peptides mostly break down in the gut. A pill version needs special formulation work to reach the blood at all.

Some compounded sellers offer a dissolving tirzepatide tablet anyway, including Henry Meds, Willow and Curex. No clinical study has tested how well these tablets are absorbed. By contrast, the FDA-approved semaglutide pills, the Wegovy pill and the Ozempic pill, use a special absorption ingredient and went through trials. If a pill matters most, semaglutide vs tirzepatide compares the two drugs directly.

Zepbound or compounded tirzepatide: which is right for you?

• You want FDA-approved manufacturing and can refill on time. Go with LillyDirect. It starts at about $300 a month and tops out near $450. Refill within 45 days to hold that top price.
• Cost is what decides it. Go compounded, starting with Mochi or Curex. Treat it as a different product from Zepbound, not a discount version of it.
• You want a pill, not a needle. A compounded tablet from Henry Meds, Willow or Curex is the only tirzepatide pill. Its absorption and safety haven't been tested in trials.
• You have insurance or Medicare. Only Zepbound can be covered. With job-based or private insurance that covers it, Lilly's savings card can bring it to as little as $25 a month. The card saves at most $100 a month. It ends December 31, 2026. With Medicare, the GLP-1 Bridge charges $50. Compounded tirzepatide is always cash-pay.
• You're unsure a seller is legitimate. Ask which licensed pharmacy fills the prescription and whether it's accredited. Also ask how the clinician documents your medical need. That applies to every compounded option on this page.

Should you compare Ozempic, Mounjaro or retatrutide instead?

A few nearby searches land here. If you're weighing a different drug against tirzepatide, these are the real comparisons.

• Ozempic is semaglutide, a truly different drug. See semaglutide vs tirzepatide for results, side effects and price side by side.
• Mounjaro is the same drug as Zepbound, approved for type 2 diabetes instead of weight loss. It has its own savings card and its own self-pay price at Lilly, about $500 a month. A Zepbound coupon won't work on a Mounjaro prescription.
• Retatrutide is a newer drug that acts on a third hormone target. It isn't FDA-approved, and no pharmacy can legally compound it. See retatrutide vs. tirzepatide for where it stands.
