Third-Party Testing

Quality Testing & Assurance

Our Commitment to Excellence

At Peptidal, quality assurance isn't just a promise—it's the foundation of everything we do. We understand that research depends on precision, reliability, and consistency. That's why every single product in our catalogue undergoes comprehensive testing protocols that exceed industry standards.

Third-Party Verification with Janoshik

We partner exclusively with Janoshik, one of Europe's most respected independent analytical laboratories, for all our quality testing. This third-party verification ensures complete objectivity and eliminates any potential conflicts of interest in our testing process.

Comprehensive Testing Protocols

Purity Analysis Every batch undergoes high-performance liquid chromatography (HPLC) analysis to determine exact purity levels. We test for:

• Primary peptide content verification
• Identification and quantification of impurities
• Related substance analysis
• Degradation product detection

Identity Confirmation Mass spectrometry testing confirms the molecular identity of each peptide, ensuring you receive exactly what you've ordered. This includes:

• Molecular weight verification
• Structural confirmation
• Amino acid sequence validation

Potency Testing Where applicable, biological activity assays verify that peptides maintain their intended potency and functionality.

Contamination Screening Rigorous testing for potential contaminants including:

• Bacterial endotoxins
• Heavy metals
• Residual solvents
• Microbial contamination

Certificate of Analysis (COA)

Every product ships with a detailed Certificate of Analysis that includes:

• Batch-specific test results
• Testing methodology details
• Purity percentages
• Janoshik laboratory signatures and dates
• Storage and handling recommendations

Quality Control Standards

Our manufacturing partners maintain:

• WHO Good Manufacturing Practice (GMP) certification
• ISO 9001:2015 quality management systems
• Regular facility audits and inspections
• Validated analytical methods
• Temperature-controlled storage and shipping

Continuous Monitoring

Quality doesn't end at manufacturing. We implement:

• Stability testing programs
• Regular re-testing of stored inventory
• Environmental monitoring during storage
• Cold chain maintenance throughout shipping

Transparency Promise

We believe in complete transparency. All testing data is available upon request, and we encourage researchers to review our methodologies. Our commitment to open communication ensures you have complete confidence in every product you receive.
