Lower values may indicate degradation or impurities. Identity Confirmation Mass spectrometry (MS) should confirm the molecular weight matches the compound. Endotoxin Levels For injectable compounds, endotoxin (LAL) testing should show <0.5 EU/mg. Sterility Sterility testing ensures no bacterial contamination. Essential for any injectable. Appearance & Solubility Physical characteristics should match expected properties of the compound.

It typically includes HPLC purity percentage, mass spectrometry (MS) confirmation of molecular weight, endotoxin levels, sterility testing, and the testing lab's name and accreditation." } }, { "@type": "Question", "name": "What peptide purity percentage should I look for on a COA?", "acceptedAnswer": { "@type": "Answer", "text": "For research peptides, look for 98% or higher purity by HPLC. Anything below 95% is considered low-grade. The COA should explicitly state the purity method (HPLC at 220 nm is standard) and show the observed molecular weight matches the expected value by mass spectrometry." } }, { "@type": "Question", "name": "How do I verify if a peptide COA is real?", "acceptedAnswer": { "@type": "Answer", "text": "Check that the COA lists a real accredited lab (Janoshik, Alkemist, or similar), a specific batch/lot number matching the product label, a test date within the past 12 months, and the testing method for each result.

Common fakes use a generic template with no batch number, copy another lab's branding, or show unrealistic 100% purity. Always cross-reference the batch number on the product with the COA, verify the lab exists, and use an analyzer tool to spot inconsistencies." } } ] } ] ```
