    Quality Control & Testing

    Every peptide we produce undergoes rigorous dual purity verification to ensure the highest standards for scientific research.

    Dual Purity Verification

    All our peptides undergo two independent purity verification tests using state-of-the-art analytical methods, ensuring consistency and reliability for your research applications.

    HPLC Analysis

    High-Performance Liquid Chromatography is performed twice by independent technicians to verify peptide purity and detect any impurities or degradation products.

    Mass Spectrometry

    Advanced MS/MS techniques confirm molecular weight and structural identity, ensuring you receive exactly what you ordered with verified composition.

    Amino Acid Analysis

    Comprehensive amino acid sequencing validates the correct peptide structure and confirms the absence of substitutions or deletions.

    Endotoxin Testing

    All peptides undergo LAL (Limulus Amebocyte Lysate) testing to ensure endotoxin levels are below acceptable limits for research use.

    Sterility Testing

    Rigorous sterility protocols and testing ensure that all peptides are free from microbial contamination and safe for research applications.

    Stability Testing

    Long-term and accelerated stability studies confirm proper storage conditions and expected shelf life for optimal research outcomes.

    Certificate of Analysis (COA)

    Each batch comes with a comprehensive Certificate of Analysis that includes:

    • Dual HPLC purity verification results (both independent tests)
    • Mass spectrometry data confirming molecular weight
    • Amino acid analysis results
    • Endotoxin testing results
    • Batch number and manufacturing date
    • Storage recommendations and expiration date

    Our Standards

    We maintain strict adherence to Good Manufacturing Practice (GMP) guidelines and operate in ISO-certified facilities. Our quality control team has decades of combined experience in peptide synthesis and analysis.

    Every peptide is guaranteed to meet or exceed 99% purity as verified by our dual testing protocol. If a product doesn't meet our stringent standards, it never reaches our customers.
