Peptide Quality & Testing FAQ

Purity is measured by High-Performance Liquid Chromatography (HPLC). A result of >99% means more than 99% of the sample is the target peptide compound, with less than 1% being impurities (truncated sequences, oxidation products, or synthesis byproducts). ORYN guarantees >99% purity for all products, verified by independent third-party laboratories.

A COA is a document from an independent laboratory that verifies the identity, purity, and quality of a peptide batch. It typically includes HPLC purity data, mass spectrometry confirmation of molecular identity, endotoxin testing results, and sterility verification. ORYN provides a batch-specific COA with every order.

GMP (Good Manufacturing Practice) is a quality standard that ensures products are consistently produced and controlled according to pharmaceutical-grade standards. ORYN peptides are manufactured in GMP-certified facilities in South Korea, with ISO 7 cleanroom conditions, validated processes, and full batch documentation.

Mass spectrometry (MS) confirms peptide identity by measuring the exact molecular weight of the compound. If the measured molecular weight matches the expected value for the target peptide, identity is confirmed. This ensures you receive the correct amino acid sequence, not a degraded or incorrect product.

Endotoxin testing (LAL test) detects bacterial endotoxins that can cause inflammatory responses and confound research results. All ORYN products pass endotoxin testing with levels well below the safety threshold of <0.25 EU/mL, ensuring your research results are not affected by bacterial contamination.

Most vial-based suppliers guarantee 95-98% purity. ORYN guarantees >99% purity. Additionally, ORYN pens undergo 0.22um sterile filtration and gamma ray sterilisation, are manufactured in GMP-certified facilities, and include batch-specific COAs from independent labs. The pre-mixed pen format also eliminates contamination risks from manual reconstitution.
