The Difference Is What the Data Proves
Every batch is tested for purity, identity, and endotoxins before it ships. All COAs are linked directly to the laboratory website for verification.
Browse testing by product & lot
Search any compound to view its lot batches and test reports — HPLC purity, mass-spec identity, and endotoxin screening. Every report opens directly on the laboratory's site.
Reports open on the independent laboratory's own verification page — view-only confirmation of each batch. Full Certificates of Analysis are available here.
≥99% Purity Standard
Confirmed via HPLC, not assumed.
LC-MS Identity Testing
Verifies exact molecular composition.
Endotoxin Testing
<1 EU/mg for sensitive applications.
Full QC Protocol
Sterility, solubility, and batch traceability.
How every batch is verified
Our benchmark is ≥99% purity across all products — a standard we consider both honest and scientifically meaningful for research-grade materials.
HPLC Purity Analysis
Analyzed on a C18 column with UV detection at 214 nm. Purity is calculated from the chromatogram — measured, never assumed.
Mass Spectrometry (MS)
Electrospray ionization measures molecular weight against the theoretical value; a ±1 Dalton match confirms the exact compound.
Endotoxin Testing
The LAL method detects bacterial contaminants. Our acceptance threshold is <1 EU/mg for demanding research environments.
Full Quality Control
Visual inspection, peptide-content verification, solubility testing, and full batch traceability from raw material to final vial.
What ≥99% Means
At least 99% of detected material is the target peptide — a transparent, defensible standard, not a vague marketing claim.
Third-Party Verification
Independent accredited laboratories validate identity, purity, and endotoxin — an unbiased layer beyond our internal testing.
Testing Frequency
Routine batch sampling, prioritizing high-volume products, new releases, and any batch approaching specification limits.
Certificate of Analysis
Each COA carries the HPLC chromatogram, mass-spec data, batch and lot ID, date of analysis, and storage guidance — and opens on the laboratory's own site, not ours.
