Our Quality Standard
Why Every Batch Gets a COA
A Certificate of Analysis is the only way to guarantee what's actually in your vial. We don't take shortcuts — every batch goes through independent testing before it ships.
At BJX PEP-TECH, every single batch we synthesize is independently tested before it ever reaches you. We use HPLC (High-Performance Liquid Chromatography) to confirm purity percentage, and mass spectrometry (MS) to verify molecular identity — the same gold-standard methods used in pharmaceutical manufacturing.
We don't just test representative samples — we test every batch, and we make those results available to you before and after purchase. No batch ships without a passing COA on file.
You can download any COA from the table below, or contact us directly with your batch number and we'll send the full report within 24 hours.
Synthesis & Formulation
Peptide synthesized under clean-room conditions using pharmaceutical-grade raw amino acid materials.
HPLC Purity Testing
Independent lab runs HPLC chromatography. We only accept results at ≥99% purity. Batches below this are rejected.
Mass Spectrometry Verification
Molecular weight confirmed by mass spectrometry to verify the correct peptide sequence and identity.
COA Issued & Logged
Full COA documentation issued by the independent lab, logged in our system, and made available for download.
Shipped with Documentation
COA included with every order. Product ships only after all tests are passed and documented.
