Our Quality
Commitment
From synthesis to shipment, every step is designed to deliver the purest research compounds available.
The Landmark Difference
Quality is not a feature - it is the foundation of everything we do. Here is how we ensure excellence.
USA-Based Operations
Landmark Biotech is headquartered and operated in the United States. We handle all sourcing, quality control, and customer support domestically.
Documented Process
Our synthesis follows documented internal quality procedures designed to support consistency from batch to batch with full audit trails.
Third-Party Tested
Every batch is independently tested for identity and content by ISO 17025-accredited labs. We publish full Certificates of Analysis for complete transparency.
99%+ Purity Standard
We maintain strict purity requirements. If a batch does not meet our 99%+ standard, it does not ship - no exceptions, no compromises.
Our Quality Process
A rigorous six-step process ensures every compound 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.
Controlled Synthesis
Solid-phase compound synthesis (SPPS) performed under controlled conditions. Each run follows validated protocols with real-time monitoring.
Purification
Reverse-phase HPLC purification removes impurities and ensures target purity levels. Multiple purification passes are performed when necessary.
Identity & Content Testing
HPLC content analysis and Mass Spectrometry identity confirmation performed on every batch by an accredited third-party laboratory.
Documentation
Full Certificate of Analysis generated with all test results. Batch records are maintained for complete traceability and auditability.
Packaging & Storage
Lyophilized compounds sealed in sterile vials under nitrogen. Climate-controlled storage maintained until the moment of shipment.
Our Commitments to You
In-House Quality Control
Our compounds are manufactured in our own USA-based facilities to internal quality and documentation standards - not outsourced.
Batch Traceability
Every vial can be traced back to its production batch with full documentation and third-party test results on file.
Continuous Improvement
We regularly audit our processes to maintain consistent quality and incorporate advances in synthesis methodology.
Transparent Communication
We openly share our quality practices and welcome questions about our processes, sourcing, and testing methodology.
