COA and Quality Assurance
A Certificate of Analysis is available for every lot, issued per-lot and linked to the specific batch received. Each COA documents peptide identity by HPLC and/or mass spectrometry and quantitative purity per component. Where applicable, reports may include additional quality parameters. COAs are matched to the exact lot shipped and held on the Lab Tests page for transparency and traceability. Eternal Peptides works with Janoshik and other established analytical laboratories.
Handling and Storage
Store the lyophilized blend at -20°C, protected from light and moisture, and keep vials sealed until reconstitution. Reconstitute using bacteriostatic water or laboratory-grade solvents appropriate to the assay; swirl gently rather than shaking. After reconstitution, aliquot to minimize repeated freeze-thaw cycles. Short-term storage at 4°C may be acceptable per protocol; longer-term storage at -20°C to -80°C depending on institutional standards. Follow institutional biosafety and chemical-handling requirements.
