Know Your Vial — AJ Peptide

Know Your Vial

We built Know Your Vial, our patient education platform, because we believe an informed patient is a safer patient. Whether you're new to peptide therapy or you've been researching it for years, we want you to be able to read a COA, understand the difference between research-use-only and pharmacy-compounded product, and ask your provider the right questions.

  • Products labeled “research use only” (RUO) are sold for laboratory work and are not intended for human use. They are not dispensed under a prescription, are not required to meet pharmacy compounding standards, and typically carry no patient-facing accountability for sterility or identity. Pharmacy-compounded medications, by contrast, are prepared by a licensed pharmacy for a specific patient pursuant to a valid prescription, under state board oversight and applicable USP standards.

  • A simplified view of how a compounded prescription reaches a patient: drug substance is received with a supplier Certificate of Analysis; the pharmacy verifies incoming material against its specifications; compounding is performed under sterile conditions per the pharmacy's procedures; finished units undergo the pharmacy's release testing and review; and the medication is dispensed to a named patient against a valid prescription.

    5. 05Dispensed to a named patient by prescription

  • A useful COA identifies the material tested, the lot, the testing laboratory, the methods used, the specification for each attribute, and the result observed. Look for identity confirmation (often mass spectrometry), purity (commonly HPLC area percent), and net peptide content — purity and net peptide content are not the same number. A percentage with no method, no lot, and no laboratory attached is not verifiable documentation.

  • Release specifications are the pre-defined limits a lot must meet before it can be released. Typical attributes include appearance, identity, purity, net peptide content, water content, residual solvents, and, for sterile preparations, sterility and endotoxin limits where applicable. Specifications are set with the pharmacy and supplier and are meaningful only when paired with a defined analytical method.

Our Standards · Quality

Documentation at both ends of the process

Quality is not a claim we make about a product; it is the paperwork, the methods, and the systems behind it. Here is what we require, at incoming and at release.

  • Before a drug substance is accepted for compounding, we expect a supplier Certificate of Analysis that identifies the manufacturer, the lot, the analytical methods used, and the result against each specification — including identity, purity, and net peptide content. A COA without methods, lot traceability, or a named testing laboratory is not accepted as documentation.

  • Finished compounded preparations are released by the pharmacy under its own documented procedures. Release documentation reflects the attributes appropriate for the preparation and its route of administration, which for sterile preparations may include sterility and endotoxin testing where applicable. We ask that release documentation be available for the lot a patient receives.

  • We work only with licensed U.S. 503A pharmacies that maintain a documented quality system: written standard operating procedures, personnel training and competency records, environmental monitoring for sterile operations, defined cleaning and disinfection programs, lot traceability, deviation and complaint handling, and defined beyond-use dating consistent with applicable USP standards.

  • We do not source from research-use-only distributors or anonymous suppliers. We do not carry compounds whose compliance status we cannot verify. We do not publish outcome claims, and we do not describe compounded products as FDA-approved, because they are not.

Important Safety Information

All products are compounded prescription medications, appropriate only for patients determined to be eligible following a medical evaluation by a licensed provider. They are not suitable for everyone. Tell your provider about all medical conditions and medications before starting treatment. These products have not been evaluated by the FDA for safety or effectiveness. Keep out of reach of children. This information is not comprehensive — consult your licensed provider for full medical guidance.
