Quality & Compliance
Independent Certifications
We frequently audit our compounds using independent, third-party laboratories. Every lot is verified before it reaches your bench, and a Certificate of Analysis is available for each batch.
Every batch is tested for
Transparent standards, verified by labs independent of our suppliers.
Identity — Mass Spectrometry
Molecular weight is confirmed by MS to verify the correct sequence and structure.
Purity — HPLC ≥99%
Reverse-phase HPLC quantifies chromatographic purity for every lot we release.
Net Peptide Content
Actual peptide mass per vial is measured so your dosing math is accurate.
Water Content
Residual moisture is checked to confirm a stable, properly lyophilized product.
Appearance & Solubility
Visual inspection and reconstitution checks confirm a clean, soluble powder.
Endotoxin Screening
Lots are screened to support sensitive in-vitro research applications.
On every Certificate of Analysis
- ✓ Product name and CAS number
- ✓ Lot / batch number and test date
- ✓ HPLC purity result and chromatogram
- ✓ Mass spectrometry identity confirmation
- ✓ Testing laboratory and method reference
