Third order now. Consistent batch-to-batch results matter enormously in long-term research. Certificate of Analysis is detailed with mass spec data. Would not switch sources.
Verified against our reference standards. Purity >98.2% by HPLC. Packaging was appropriate for temperature-sensitive peptides. Will re-order.
