Quality Assurance
Third-party tested. Every batch.
Independent laboratory verification is the cornerstone of our quality program. We don't just claim purity — we prove it with data you can review.
Our Testing Methodology
Two complementary analytical techniques verify identity and purity
HPLC Testing
High-Performance Liquid Chromatography separates and quantifies each component in a peptide sample. Our HPLC analysis confirms:
- Purity ≥99% (area percentage)
- Detection of impurities and byproducts
- Retention time matching reference standards
- Batch-to-batch consistency
Mass Spectrometry
Mass spectrometry determines the molecular weight of the peptide, confirming its identity. Our MS analysis verifies:
- Molecular weight matches theoretical value
- Peptide sequence identity confirmed
- Detection of truncated or modified sequences
- Consistency across manufacturing lots
