The Difference Is What the Data Proves
In an industry filled with recycled COAs and vague purity claims, BRP treats testing as proof — not a checkbox. Every batch undergoes rigorous, multi-stage verification before it ever reaches your lab. Researchers deserve more than marketing claims; they deserve proof.
Browse testing by product & lot
Search any compound to view its lot batches and test reports — HPLC purity, mass-spec identity, and endotoxin screening.


Reports open on the independent lab's (Janoshik) verification page — view-only confirmation of each batch. A full Certificate of Analysis is included with every order.
≥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 ISO 17025 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.
