Our Quality Commitment

From synthesis to shipment, every step is designed to deliver the purest peptides for your research.

The Pèptido Lab Difference

Quality isn't just a feature—it's the foundation of everything we do. Here's how we ensure excellence.

USA-Based Company

Pèptido Lab is proudly based in the United States. We handle all sourcing, quality control, and customer support from our US operations.

cGMP Compliance

Our manufacturing partners follow Current Good Manufacturing Practices, the same standards required for pharmaceutical production.

Third-Party Testing

Every batch is independently tested by ISO 17025 accredited laboratories. We publish full Certificates of Analysis for complete transparency.

99%+ Purity Standard

We maintain strict purity requirements. If a batch doesn't meet our 99%+ standard, it doesn't ship—no exceptions.

Our Quality Process

A rigorous six-step process ensures every peptide meets our exacting standards.

Raw Material Verification

All raw materials undergo identity and purity testing before synthesis begins. We verify amino acid purity, solvent quality, and reagent specifications.

Peptide Synthesis

Solid-phase peptide synthesis (SPPS) in controlled cleanroom environments. Each synthesis follows validated protocols with real-time monitoring.

Purification

Reverse-phase HPLC purification removes impurities and ensures target purity levels. Multiple purification passes when necessary.

Quality Testing

HPLC purity analysis, Mass Spectrometry identity confirmation, endotoxin testing, and sterility verification on every batch.

Documentation

Full Certificate of Analysis generated with all test results. Batch records maintained for complete traceability.

Packaging & Storage

Lyophilized peptides sealed in sterile vials under nitrogen. Climate-controlled storage until shipment.

Our Commitments to You

cGMP-Certified Partners

We only work with manufacturers that meet strict cGMP standards, ensuring pharmaceutical-grade quality.

Batch Traceability

Every vial can be traced back to its production batch with full documentation.

Continuous Improvement

We regularly audit our processes and partners to maintain the highest standards.

Transparent Communication

We openly share our quality practices and welcome questions about our processes.

All the research peptides you need, with the peace of mind and research community at your fingertips.
