Quality & Transparency
Where this comes from, and how we know what's in it
Licensed US pharmacies, independent batch testing, and a plain account of the limits — including what we can't promise.
Where products are made
Everything dispensed through our clinical partner comes from a licensed US pharmacy — either a 503A compounding pharmacy or an FDA-registered 503B outsourcing facility. Those two terms come from the US Food, Drug & Cosmetic Act, and the difference is worth understanding.
503A compounding pharmacy
A state-licensed pharmacy that prepares a medication for one named patient against one prescription. Nothing is made until a provider writes for it. 503A pharmacies are licensed and inspected by state boards of pharmacy and work under USP standards for sterile preparation.
- Patient-specific — made after your prescription is received
- Licensed and inspected by state boards of pharmacy
- Allows individualized strengths and combinations
503B outsourcing facility
A facility registered with the FDA that produces sterile medications in batches, without needing a patient name in advance. 503B facilities operate under Current Good Manufacturing Practice (CGMP) requirements and are subject to FDA inspection.
- Batch production under CGMP requirements
- Registered with and inspected by the FDA
- Batch records and release testing for each lot
Third-party testing
Batches are sent to independent laboratories — labs with no stake in the result — and released against the certificate of analysis they return. In-house testing alone isn't good enough, because the party being checked shouldn't be the party doing the checking.
| What's tested | Why it matters |
|---|---|
| Identity | Confirms the vial contains the peptide or molecule on the label — not a different or substituted compound. |
| Potency / assay | Confirms the strength matches the label, so a prescribed dose is the dose actually delivered. |
| Sterility | Confirms no viable microorganisms are present. Critical for anything injected. |
| Bacterial endotoxin | Detects fever-causing bacterial fragments that survive sterilization and are not covered by a sterility test alone. |
| Purity / related substances | Measures impurities and degradation products from synthesis or storage. |
| Residual solvents | Confirms solvents used in manufacturing have been removed to within accepted limits. |
Testing scope varies by product and dosage form. Sterility and endotoxin testing apply to sterile injectables; residual solvent testing applies where solvents are used in synthesis.
What "compounded" means
A compounded medication is prepared by a pharmacy for a patient, rather than manufactured at scale and sold in a sealed commercial package. It's how pharmacies have always handled a strength that isn't sold commercially, a combination that fits one protocol, an ingredient a patient reacts to, or a shortage of the commercial product.
| Compounded preparation | Mass-produced drug | |
|---|---|---|
| Made for | A specific patient or a pharmacy batch | The general market |
| FDA approval | Not FDA-approved as a product | Approved for a specific indication |
| Oversight | State pharmacy boards; FDA for 503B facilities | FDA approval plus CGMP manufacturing |
| Flexibility | Custom strengths, forms and combinations | Fixed strengths and forms only |
| Quality evidence | Batch testing and certificates of analysis | Approval dossier plus batch release testing |
The short version: the pharmacy is licensed and inspected, and the batch is tested — but the compounded preparation itself has not been reviewed or approved by the FDA. Both of those things are true at once, and you should weigh them with a provider.
What we can't promise
If a wellness brand only tells you what it can do, it's selling. Here is the other half.
We can't promise results.
Nobody can. Response varies with your physiology, dose, adherence, sleep, nutrition, training and medical history. Some people see meaningful change; some see little or none. Any timeline you're given is an average, not a commitment.
Most of these uses are not FDA-approved.
Compounded medications are not FDA-approved products. A facility can be licensed, registered and inspected while the specific preparation it makes has never gone through FDA review for safety or efficacy. Some ingredients here exist in FDA-approved products for a specific indication; that approval does not extend to a compounded version or to a different use.
Testing verifies the vial, not the outcome.
A certificate of analysis tells you the contents are what the label says, at the stated strength, without contamination. It says nothing about whether the product will work for you.
Clinical evidence is uneven.
Some of these molecules have large human trials behind them. Others rest mostly on animal data, small studies, or mechanism-based reasoning. We won't dress the second group up as the first.
There are real side effects, and a provider may say no.
Every product page lists common side effects and who should avoid it. A licensed provider can decline to prescribe, and we do not override that decision.
Nothing here diagnoses, treats, cures or prevents disease.
This site is education. It is not medical advice, and it is not a substitute for care from your own physician.
Questions about your own situation belong with a licensed provider — see how the process works or the FAQ.
