Quick answer

You can check a 503A compounding pharmacy for free in four steps. Look up its license on your state board of pharmacy's database (FDA links to every state's), search FDA's compounding inspections and recalls page for its legal name and any "doing business as" name, ask for the certificate of analysis for your lot, and check the peptide itself on FDA's list of substances that may present safety risks. FDA says that if an online pharmacy isn't listed with your state board, you shouldn't use it.

Key takeaways

  • Start with the license: find the pharmacy in your state board of pharmacy's database through FDA's locator, and if it isn't listed, FDA says not to use it.
  • A 503A pharmacy compounds for one patient on a prescription and answers mainly to state boards, a 503B outsourcing facility registers with FDA, and neither type gets FDA approval before its medicines are sold.
  • Search FDA's "Compounding: Inspections, Recalls, and other Actions" page under both the pharmacy's legal name and its storefront name, and read any Form 483 in context.
  • Ask for the certificate of analysis for your lot and match the lot number, measured strength, passing range and test method to your vial.
  • A 503A pharmacy can't compound any peptide it wants, so check your peptide on FDA's safety-risk page and take what you find to your clinical team.

You can check a 503A compounding pharmacy yourself, for free, in about the time it takes to order the peptide. First, look up its license on your state board of pharmacy's database. FDA links to every state's database from its online pharmacy license locator. Next, search FDA's compounding inspections and recalls page for the pharmacy's name. Then ask for the certificate of analysis for your lot. FDA's own advice is blunt: if an online pharmacy isn't listed with your state board, don't use it.

A state license is the minimum a pharmacy needs. It doesn't prove your vial is good. The lot certificate and a check on the peptide itself tell you more, so this guide covers all four checks and shows you how to read each record.

How do I look up a compounding pharmacy's license with my state board?

  1. Find the state database. Go to FDA's Locate a State-Licensed Online Pharmacy page, click your state and search for the pharmacy in that state's board of pharmacy database. If it isn't listed, FDA says not to use it.
  2. Confirm the three things FDA asks for. The pharmacy requires a prescription, gives a physical U.S. address and phone number, and has a licensed pharmacist who will answer your questions.
  3. Search two boards. Check the board in the pharmacy's home state as well as your own. Match the exact legal name and address on the license to the name on your label.
  4. Look for discipline separately. A clean license search can lag behind disciplinary orders. Texas, for example, says its license data is current as of the previous work day, except for information about disciplinary orders. It also offers an open records request form if you want more.

This first check screens out a lot of bad sellers. Researchers writing in JAMA Health Forum reported that nearly half of online pharmacies offering semaglutide may be operating illegally, running scams where nothing is delivered, or selling products that don't meet quality standards.

What's the difference between a 503A pharmacy and a 503B outsourcing facility?

For a 503A, your state board is the main place to check. Neither type of compounded medicine goes through FDA approval before it's sold, so checking the pharmacy falls to you. A seller that ships you a peptide without a prescription isn't working the way a 503A pharmacy should, whatever its website says.

Where do I find a compounding pharmacy's FDA inspection report?

FDA keeps a public page called "Compounding: Inspections, Recalls, and other Actions." It lists pharmacies by name, with entries such as Form 483s, warning letters, warning letter close-outs and referral letters to state boards of pharmacy. A Form 483 is the form inspectors issue that lists what they found. Search the page for the pharmacy's legal name and for any "dba" (doing business as) name.

Search both names, because the legal name and the name on the storefront often differ. FDA lists "Prescription Labs, Inc. (dba Greenpark Compounding Pharmacy)" in Houston, with a 483 issued in August 2021. That entry links to a September 2021 FDA press release telling patients and health care professionals not to use the pharmacy's compounded products meant to be sterile. If you searched only "Greenpark," you could miss it.

Read what you find in context. A single 483 followed by a close-out reads differently from repeated 483s, a referral to a state board or an FDA warning to patients. Open the PDF, read what inspectors saw, and ask the pharmacy what they fixed. A missing license should stop you. One inspection finding with a documented fix doesn't have to.

If the pharmacy isn't on FDA's page, look for inspection records at the state board next, often through an open records request. Texas provides an open records request form and a page to verify inspectors for Class E-S pharmacies (out-of-state pharmacies that do sterile compounding).

What should a peptide's certificate of analysis show?

Under federal rules, the raw ingredient a 503A pharmacy compounds from must come with a valid certificate of analysis and be made by an FDA-registered manufacturer. FDA also urges compounders to know their supplier. Asking to see that paperwork is a fair request.

Go a step further and ask for the certificate of analysis for your lot, from an outside lab. One Reddit user asked her pharmacy directly and received outside-lab potency reports for compounded tirzepatide. Her report read "Tested concentration: 9.9225 mg/mL," "Assay: 99.2%," "Specification: 90–110%" and "Tested by HPLC." She added: "My vial is lot 574691, so my lot is specifically listed on that report."

Her report shows the four things to match on yours:

  • Lot number: your vial's lot appears on the report.
  • Measured strength: the tested concentration sits close to the strength on your label.
  • Passing range: the result falls inside the stated specification.
  • Test method: the report names how the lab tested it, such as HPLC (a standard lab method for measuring how much drug is in a sample).

Your lot is what you're injecting, and it matters more than the pharmacy's best batch. In a lab study of compounded semaglutide, two samples from the same pharmacy, compounded within one week, varied significantly from each other. Some samples also contained traces of other medicines, and strength and impurities shifted when the products were exposed to light.

So a percentage quoted on a website or by a provider ("over 99% purity") isn't the same as a lot report with your lot number on it. Ask for the document, and store the vial the way the label says.

Can a licensed 503A pharmacy compound any peptide it wants?

No. A 503A pharmacy may only compound from ingredients that meet a USP or NF standard (official quality standards for drug ingredients) where one exists, that are part of an FDA-approved drug, or that appear on FDA's 503A bulks list. While FDA reviews substances people have nominated for that list, it sorts them into categories 1, 2 and 3 under an interim policy.

Category 2 holds substances FDA has identified as possible significant safety risks. FDA publishes them on a page called "Certain Bulk Drug Substances for Use in Compounding that May Present Significant Safety Risks." Search it for the peptide you're prescribed. A peptide missing from that page isn't approved by default, so use this check alongside the license and lot checks above.

BPC-157 is one example. It appears on that page as a nomination that was withdrawn. FDA's note says compounded BPC-157 may pose a risk of immune reactions for certain routes, that its peptide-related impurities and ingredient makeup can be complex to characterize, and that FDA has found no or only limited safety information for the proposed routes. If BPC-157 is part of your recovery plan, ask your clinical team what that note means for you and what to watch for.

Your clinical team is the right place to take anything you find. Ask which pharmacy fills your prescription, then run the same four checks on it.

You want the peptide that fits your goal, whether that's recovery, skin or energy, from a pharmacy you've checked yourself. Take the quiz to start a plan with our clinical team. You can ask which pharmacy fills your prescription and run these checks before your first dose.

FAQ

Are compounded peptides FDA approved?

No. Medicines made by 503A compounding pharmacies and 503B outsourcing facilities don't go through FDA approval before they're sold. A 503A pharmacy can only compound from ingredients that meet an official quality standard, are part of an FDA-approved drug, or appear on FDA's 503A bulks list. That's why checking the pharmacy's license, inspection record and lot report is worth doing.

What does an FDA Form 483 mean for a pharmacy?

A Form 483 is the form FDA inspectors issue that lists what they found during an inspection. It appears on FDA's compounding inspections page alongside warning letters, close-outs and referrals to state boards. A single 483 followed by a close-out reads differently from repeated 483s, a state board referral or an FDA warning to patients. Open the PDF, read what inspectors saw and ask the pharmacy what they fixed.

How do I know if a peptide website is a real pharmacy?

A real pharmacy is listed in a state board of pharmacy database, requires a prescription, gives a physical U.S. address and phone number, and has a licensed pharmacist to answer your questions. Check the board in the pharmacy's home state and in your own, and match the legal name and address to your label. A seller that ships a peptide without a prescription isn't working the way a 503A pharmacy should. Researchers in JAMA Health Forum reported that nearly half of online pharmacies offering semaglutide may be operating illegally, running scams or selling products that don't meet quality standards.

Can I ask my pharmacy for a certificate of analysis for my lot?

Yes, asking for the paperwork is a fair request. One Reddit user asked her pharmacy directly and received outside-lab potency reports for tirzepatide that listed her vial's lot number. Check that the report shows your lot number, a measured strength close to your label, a result inside the passing range and the test method used. A purity percentage quoted on a website isn't the same as a report with your lot on it.
