Testing and Documentation for Research Peptides

This page describes only the analytical documentation Amino Fuel Labs can show you. For each method we state what it measures and, just as importantly, what it does not prove. Where we hold no documentation, we make no claim.

Evaluate third-party tested research peptides through the documents available for the specific material. Start with the compound name and lot identifier, then review the testing laboratory, methods and reported results. Assess a batch-specific peptide COA alongside the product specifications, and clarify any missing information before selecting material. HPLC purity and net peptide content are different measurements; see peptide purity versus net peptide content for a detailed explanation.

All products are supplied for laboratory research use only, and not for diagnostic or therapeutic application.

Analytical methods we document

Reversed-phase HPLC (purity)

What it measures: Separates the target peptide from process-related impurities and reports the target peak as a percentage of total peak area for the tested lot.

What it does not prove: It does not confirm molecular identity on its own, does not measure sterility, and does not describe biological activity.

Mass spectrometry (ESI-MS)

What it measures: Detects the molecular mass of the tested material against the expected mass of the declared sequence and reports the target mass as a percentage of the measured signal for that lot.

What it does not prove: It does not detect every co-eluting impurity, is not a substitute for the HPLC purity figure, and says nothing about handling after the material leaves the laboratory.

LAL endotoxin test

What it measures: Reports the bacterial endotoxin level of the tested lot, expressed in endotoxin units per milligram on the Certificate of Analysis.

What it does not prove: An endotoxin result is not a sterility test, does not certify the material as pyrogen-free for any application, and applies only to the lot tested.

Lot matching

What it measures: Each Certificate of Analysis is tied to a specific lot number printed on the vial label so documentation and material can be reconciled on receipt.

What it does not prove: A certificate for one lot never applies to another lot, and a matching document does not verify storage conditions during transit or in your facility.

Verified statements

Intended use: Laboratory research use only

What we do not claim

Amino Fuel Labs holds no accreditation of its own and claims no cGMP compliance, cleanroom classification or domestic synthesis. Results such as endotoxin, sterility, residual solvents, heavy metals and microbial limits are reported per lot on the Certificate of Analysis, by the testing laboratory named on that document, and apply only to the lot tested. If a supplier states more than that, ask for the certificate that carries the accrediting body, the scope, and an expiry date.

Verify a document

Every listed compound has a lot-matched Certificate of Analysis in the COA library. Compare the lot number on the certificate with the lot printed on the vial before use in any protocol.
