How do I read a Certificate of Analysis for research peptides?
A Certificate of Analysis (COA) for research peptides includes the product name, batch number, testing date, and purity percentage verified by HPLC or mass spectrometry. At AREA 15 LABS, every COA shows the exact peptide sequence, molecular weight, and third-party lab verification. Look for purity at or above 99% and matching batch numbers on your product label.
What purity standards does AREA 15 LABS require for peptide testing?
AREA 15 LABS requires a minimum of 99%+ HPLC-verified purity for all research peptides. Each batch is tested by independent U.S.-based laboratories before release. We do not sell peptides that fail to meet this standard.
How often are COAs updated for new peptide batches?
COAs are updated as new inventory is tested and verified by our third-party U.S.-based laboratories. Each product page links to the most current Certificate of Analysis, which includes a QR code for quick verification.
Can I verify a COA with the third-party testing lab directly?
Yes. Every AREA 15 LABS COA includes the testing laboratory name and a QR code linking to the verification page. Researchers can scan the QR code on their COA or contact the lab directly using the test date and peptide name provided.
What is the difference between HPLC and MS testing for peptides?
HPLC (High-Performance Liquid Chromatography) measures purity by separating compounds based on chemical properties. MS (Mass Spectrometry) confirms molecular weight and peptide identity. AREA 15 LABS uses both methods to verify that peptides are pure, correctly sequenced, and free from contaminants.
How should I store lyophilized research peptides after verifying COA?
Store lyophilized research peptides in a cool, dry place away from direct light. For maximum stability, refrigerate at 2–8°C (36–46°F). Reconstitute according to your research protocol. Proper storage preserves peptide integrity after COA verification.
Why does AREA 15 LABS use U.S.-based laboratories for peptide testing?
U.S.-based laboratories follow strict quality control standards and regulatory compliance for analytical testing. Using domestic labs ensures consistent, reliable results that researchers can trust and verify independently.
What does 99%+ HPLC verified mean on a peptide COA?
99%+ HPLC verified means the peptide is at least 99% pure based on chromatographic analysis. The remaining less than 1% consists of acceptable trace impurities that do not affect research integrity. This is the industry standard for high-quality research peptides.
