Compounded tirzepatide formulation challenges — stability data

Here's the current status as of June 2026:

Legal status: Complicated. FDA removed tirzepatide from the shortage list in October 2024 and has been issuing warning letters and cease-and-desist orders to compounders. HOWEVER, multiple lawsuits are challenging these enforcement actions, and some pharmacies have obtained temporary restraining orders allowing them to continue compounding.

Availability: Reduced but not eliminated. Several 503B facilities stopped voluntarily. Others are still compounding under legal protection from court orders. Some 503A pharmacies argue they're exempt from the enforcement because they compound on a patient-specific basis.

Pricing (where available):

• Compounded tirzepatide 10mg vial: $150-275/month
• Compounded tirzepatide 30mg vial: $300-450 (multi-month supply at lower doses)

Compare to brand Mounjaro/Zepbound at $1,050-1,200/month without insurance.

The key legal case right now is the litigation in the 5th Circuit involving the Outsourcing Facilities Association. The core argument is whether compounded tirzepatide using a different salt form constitutes an "essentially a copy" of branded Mounjaro/Zepbound. If the courts rule it's NOT a copy, compounding could resume broadly.

There's also a constitutional argument about FDA overreach in enforcement. Some pharmacies argue that FDA's administrative determination that the shortage ended is arbitrary and capricious because patients still can't access the medication due to cost.

It's a legal mess. But the practical takeaway: compounded tirzepatide is still available from some pharmacies, just fewer than before.

So if I find a pharmacy still compounding it, am I taking any legal risk as a patient? Can FDA come after me for buying it?

No. FDA enforcement actions target pharmacies and prescribers, not patients. You are not breaking any law by filling a valid prescription for a compounded medication. The legal risk sits entirely with the pharmacy and potentially the prescriber.

That said, availability risk is real. If your pharmacy gets shut down mid-treatment, you're back to square one (see the "pharmacy shut down" thread).
