Compounded tirzepatide vs Zepbound vs Mounjaro
These names get used interchangeably, and that confuses a lot of people. The short version: it is all tirzepatide. The real differences are the product form and the price. Here is the honest breakdown, with no spin in either direction.

They are all the same active drug
Zepbound and Mounjaro are both brand-name tirzepatide made by Eli Lilly. The active molecule inside them is identical. What separates the two is the use the FDA approved them for:
- Mounjaro is approved for type 2 diabetes.
- Zepbound is approved for chronic weight management, and for obstructive sleep apnea in adults with obesity.
Compounded tirzepatide is that same active molecule, tirzepatide, prepared by a compounding pharmacy or outsourcing facility rather than sold as the finished brand product. If you want the deeper comparison between this medication and the other major GLP-1, see tirzepatide vs semaglutide.
Brand vs compounded: the honest difference
We are not going to bash the brands. Zepbound and Mounjaro are FDA-approved finished drugs from Eli Lilly, and that approval means the finished product itself has been reviewed by the FDA. That is a real distinction worth understanding.
Compounded tirzepatide is not FDA-approved as a finished product. What it offers is the same active drug at a fraction of the price. The quality question with any compounded medication is who makes it and where. Crossing's compounded tirzepatide is manufactured by BPI Labs, an FDA-registered 503B outsourcing facility in Largo, Florida that operates under cGMP standards, and it is dispensed by The Pharmacy Hub, a licensed 503A pharmacy. It is compounded with vitamin B6. So the difference comes down to two things: the brand is a finished, FDA-approved product, and the compounded version is the same molecule made at a registered facility for far less money.
What each one costs
Most people paying for tirzepatide pay cash, because insurance coverage for GLP-1 medications is inconsistent and often excludes weight management entirely. So the cash price is the number that actually matters. Here is where the three options land.
| Option | Typical cost | What to know |
|---|---|---|
| Brand Zepbound / Mounjaro | $1,000+ / mo | List price without insurance. These are Eli Lilly's FDA-approved finished drugs. Self-pay vials run a few hundred dollars at the lowest doses, but the published list price sits above $1,000 a month. |
| Other telehealth (compounded) | $399–$499 / mo | Same active molecule as the brand, made by a compounding pharmacy. Usually billed three months upfront, often with a higher re-order price after the intro block. |
| Crossing (compounded) | $149 / mo | One flat price at every dose. Medication, provider review, increasing-dose plan, shipping, and unlimited messaging included. Billed monthly, cancel anytime. |
Crossing is $149 a month, all in. The same price at every dose, billed monthly, cancel anytime.
Why other compounded prices are higher than they look
If the active drug is the same, why do other telehealth providers charge $399 to $499 a month for compounded tirzepatide? Two reasons usually drive it. The first is the upfront block: you pay for three months at once to unlock the advertised rate. The second is the re-order jump, where a low starter price quietly rises after your first order.
Crossing does neither. You pay $149 this month, $149 next month, and $149 at every dose after that. There is no dose-based upcharge, no membership fee, no bundle requirement, and no surprise add-on at checkout. You can see exactly where every dollar goes, read the full tirzepatide cost breakdown, or look at the compounded tirzepatide product itself.
How starting works
Tirzepatide is prescription-only, so you start with a roughly 10-minute online visit. A provider licensed in your state reviews your information, and if the medication is appropriate, it ships to you. We place a card hold at checkout and only charge you if you're approved. Every plan comes with a 30-day money-back guarantee, so you can try it with the price and the terms fully on the table.
Common questions
Is compounded tirzepatide the same as Zepbound and Mounjaro?
It is the same active molecule, tirzepatide. Zepbound and Mounjaro are Eli Lilly's brand-name, FDA-approved finished products. Compounded tirzepatide is that same active drug prepared by a compounding pharmacy or outsourcing facility, not sold as the finished brand product. Crossing's is made by BPI Labs, an FDA-registered 503B outsourcing facility, and dispensed by The Pharmacy Hub, a licensed 503A pharmacy.
What is the difference between Zepbound and Mounjaro?
Both are brand-name tirzepatide from Eli Lilly, so the active drug is identical. They differ by FDA-approved use: Mounjaro is approved for type 2 diabetes, and Zepbound is approved for chronic weight management (and for obstructive sleep apnea in adults with obesity). Your provider determines what is appropriate for you.
Why is compounded tirzepatide so much cheaper than the brand?
Compounded tirzepatide is prepared from the same active ingredient rather than sold as a finished brand-name product, so it skips the brand markup. Brand Zepbound and Mounjaro list at over $1,000 a month without insurance. Other telehealth providers price compounded tirzepatide at $399 to $499 a month, often billed three months upfront. Crossing is one flat $149 a month at every dose.
Is compounded tirzepatide FDA-approved?
No. The brand finished products (Zepbound and Mounjaro) are FDA-approved drugs; compounded versions are not FDA-approved as finished products. Crossing's compounded tirzepatide is made at an FDA-registered 503B outsourcing facility under cGMP standards and is prescription-only, so a licensed provider must review your information before anything ships.
