How Transformation Health Vets Its Compounding Pharmacies
If you are close to starting a GLP-1 program, you have probably narrowed the question down to something simple and important: where does my medication actually come from, and how do I know it is safe? This page is our honest answer. It explains the standard a compounding pharmacy has to meet before Transformation Health will work with it, and why the source of a compounded medication is the single biggest factor in its quality.
Why pharmacy selection matters
Compounded medications are not uniform. Two vials labeled the same way can come from operations with very different practices, and the difference is not something you can see by looking at the label. The pharmacy that prepares your medication, the ingredients it uses, the testing it performs, and the oversight it answers to are what actually determine quality.
That is why pharmacy selection is the most important decision behind your program. It is also why so much of the public concern about compounded GLP-1 medications traces back to where a product came from rather than to compounding itself. Legitimate, state-licensed compounding pharmacies operate under real guardrails. Unregulated online sellers, “research peptide” vendors, and overseas operations do not. The gap between those two is the gap we built our vetting process to close.
To be clear about who we are: Transformation Health is a technology platform that connects you with independent, licensed providers and with vetted pharmacy partners. We do not prescribe, and we do not compound. What we do is set the standard a pharmacy has to meet to be part of the network, and hold partners to it.
Our standards for a pharmacy partner
Before a pharmacy can prepare medication for anyone in our network, it has to meet the criteria below. These are the same credentials a careful patient would look for on their own. We just make them a requirement rather than a hope.
State pharmacy licensure
Every pharmacy partner holds an active license from the state pharmacy board where it operates and employs a licensed pharmacist who oversees compounding. This is the non-negotiable baseline. You can verify a pharmacy's license yourself through the state pharmacy board's public records.
PCAB accreditation as a quality signal
We treat accreditation from the Pharmacy Compounding Accreditation Board (PCAB) as a meaningful indicator of quality above the regulatory minimum. It involves site inspections and documentation review. It is not required for a pharmacy to be legitimate, so we weigh it alongside the other criteria rather than relying on it alone.
Certificate of analysis and batch testing
A responsible pharmacy tests each batch through an independent laboratory for potency, purity, and sterility, and provides a certificate of analysis (COA). A COA lets you confirm that your medication contains the labeled amount of active ingredient and is free of contaminants. We require this documentation to be available for the batches our partners prepare.
503A vs 503B and FDA registration
Pharmacies operate under one of two models. 503A pharmacies work under state board oversight. 503B outsourcing facilities are additionally registered with the FDA and inspected against federal manufacturing standards. Neither is inherently superior, and both can be legitimate. Important: FDA registration of a 503B facility is not the same as FDA approval of the product it prepares.
US-based facilities only
Every pharmacy partner operates and ships from within the United States, where it is subject to state pharmacy board oversight and, for 503B facilities, FDA inspection. We do not work with any pharmacy that cannot be identified at a verifiable US address.
A valid prescription, every time
Medication is prepared only after an independent, licensed provider has written a valid prescription for a specific patient. No partner in our network dispenses GLP-1 medication without a prescription, and we do not participate in any process that skips provider review.
Taken together, these standards mean your medication is prepared by a licensed US pharmacy, rigorously tested before it reaches you, and dispensed only on the authority of a prescription written for you. It is not FDA-approved, but there are real, verifiable controls behind it.
What we do not do
It helps to be just as clear about what is out of bounds. The practices below are common among unregulated sellers and are exactly the ones the FDA has acted against. Transformation Health does not engage in any of them.
We do not source from overseas facilities. Operations outside the US are not subject to state pharmacy board oversight or FDA inspection, and they are not bound by US pharmacy regulations. We do not use them, regardless of cost or convenience.
We do not work with unlicensed facilities. If a pharmacy cannot demonstrate an active state license and a licensed pharmacist on staff, it is not eligible to be a partner. The same applies to anyone selling products labeled “research peptide” or “not for human use” to sidestep pharmacy law.
We do not dispense without a prescription. There is no path through Transformation Health to receive GLP-1 medication without an evaluation by an independent, licensed provider. Any service that offers medication with “no medical review needed” is operating outside the rules, and we are not one of them.
The role of the independent provider
The clinical decision is never ours, and it is never the pharmacy’s. It belongs to an independent, licensed provider.
When you complete your assessment, an independent provider reviews your health history, current medications, and goals, and determines whether treatment is medically appropriate for you. This is not automatic, and not everyone qualifies. The provider, not Transformation Health and not the pharmacy, decides whether a prescription should be written and what it should be.
This separation is a safety feature in itself. Transformation Health is the technology platform that connects you with that provider and routes a valid prescription to a vetted pharmacy. We do not prescribe. Keeping the clinical judgment with a licensed provider who knows your history is how the process is supposed to work, and how ours is built.
How you can verify quality yourself
You do not have to take our word for any of this. The same credentials we require are ones you can check on your own, and we encourage you to.
You can ask which specific pharmacy is preparing your medication and look up its license through the state pharmacy board’s public database. You can ask whether the pharmacy is PCAB-accredited. You can request the certificate of analysis for your batch and confirm it shows recent testing for potency, purity, and sterility. A legitimate pharmacy provides this information without hesitation.

Get StartedImportant disclosures
Transformation Health is a technology platform that connects patients with independent, licensed healthcare providers and with vetted compounding pharmacy partners. We do not prescribe medication and we do not compound it. All prescribing decisions are made by an independent, licensed provider who reviews your individual health history. Not all patients will qualify, and results vary from person to person.
The standards described on this page reflect the criteria we apply when selecting and monitoring pharmacy partners. Compounded GLP-1 medications are not the same as brand-name GLP-1 medications, and the FDA registration of a 503B outsourcing facility is not the same as FDA approval of the product it prepares.
Availability of compounded GLP-1 medications depends on FDA drug shortage-list status and on applicable state and federal pharmacy compounding laws, which can change. We monitor the regulatory landscape and work to operate within it at all times.
Important: Compounded GLP-1 medications are not FDA-approved products. They are prepared by US-based, state-licensed compounding pharmacies and have not been independently evaluated by the FDA for safety, efficacy, or quality. Compounded medications are not the same as brand-name GLP-1 products, which are registered trademarks of their respective manufacturers. Transformation Health is not affiliated with or endorsed by those manufacturers. All prescriptions require evaluation by an independent, licensed healthcare provider. Not all patients will qualify. Results vary by individual. Availability of compounded GLP-1 medications is subject to FDA drug shortage-list status and applicable state and federal pharmacy compounding laws, which may change.
