Quality Control and Testing Methodology
This page explains what testing Caliber Research commissions, what that testing establishes, and what it does not. All materials are supplied for research purposes only.
Independent testing before release
Caliber Research does not test its own material. Testing is commissioned from independent laboratories. Reports produced by a supplier are not presented as our public testing evidence — the reports in the Quality Reports archive are the ones we commissioned.
No batch is released for sale until independent testing is complete.
Analytical methods are selected by the performing laboratory and may differ by report, batch, or compound. The applicable Quality Report identifies the method used.
Testing performed on every batch
Three tests are performed on every batch. Testing requirements do not vary by compound.
Mass and purity
Mass and purity testing reports the measured quantity and purity result for the submitted sample using the laboratory’s stated analytical method. Results apply only to the tested sample and batch. A purity result is a measurement produced by a stated method; it is not a complete accounting of every component present, and it does not extend to any other batch.
Identity
Identity testing is intended to confirm that the submitted sample corresponds to the compound named on the label, using the laboratory’s stated analytical method. Confirming analytical identity is distinct from establishing that material is suitable for any particular use. An identity result answers which compound was tested — not whether it is appropriate for a given purpose.
Endotoxins
Endotoxin testing measures bacterial endotoxin in the submitted sample. It is distinct from sterility testing and should not be interpreted as a sterility result. Results apply only to the submitted sample and batch.
Why concentration testing does not apply
Compounds are supplied as lyophilized powders, not as prepared liquid solutions. There is no prepared solution to test, so concentration testing is not part of the standard testing program. Mass-related questions are addressed through the mass and purity testing described above.
Sterility testing is not normally performed
Sterility testing is not normally performed on Caliber Research batches, and nothing in our documentation should be read as a sterility claim. Endotoxin testing is not sterility testing: it measures bacterial endotoxin in the submitted sample and should not be interpreted as a sterility result.
Batch traceability
Every unit is assigned to a specific batch, and every batch carries its own reports. Batches are fulfilled in FIFO order: the current batch is the first to ship, with queued batches listed in order behind it. Because reports belong to batches rather than to product listings, a report is meaningful only when matched to the batch it describes.
Final Lab Tests in Progress
When the catalog shows Final Lab Tests in Progress, inventory has been received but its independent testing is not complete. The item is not available for normal ordering and has not been released for sale. It becomes orderable once testing is complete and the results have been reviewed.
Historical quality reports
The Quality Reports archive is permanent. Reports for past and retired batches are retained rather than replaced. The archive listing — compound, batch, and which reports exist — is public. Access to the underlying report files is limited to registered members under Caliber Research’s current document-access policy.
Understanding the limits of testing
A report documents the tests shown on it, performed on the submitted sample, by the laboratory that ran them, using that laboratory’s stated method. It does not establish safety, sterility, efficacy, or suitability for any use, and it does not carry across to a different batch.
Research use only
For research purposes only. No human or veterinary use. Products are not intended to diagnose, treat, cure, or prevent any disease or condition.
