How do I verify the COA for my specific vial lot?
Every PEPTYZ reference standard vial displays a unique alphanumeric Lot Number (e.g., MC-4491, BP-9042). Visit our
COA Library, enter your code into the search field, and instantly view or download the complete third-party HPLC chromatogram and LC-MS spectrometry report.
What analytical purity threshold is guaranteed?
All PEPTYZ reference standards are guaranteed ≥99.0% purity as assayed by independent ISO/IEC 17025 accredited laboratories. Exact batch purity percentages are documented on each Certificate of Analysis.
What are the recommended storage temperatures?
Lyophilized powders should be stored at -20°C in a dry environment protected from light. Once reconstituted, solutions should be kept refrigerated between 2°C and 8°C and tested within protocol timelines to prevent hydrolysis.
How is cold shipping packaged and dispatched?
Orders are dispatched within 24 hours in insulated thermal mailers with cold gel packs. All packages are shipped with discreet labelling, tracking, and full insurance. Orders over $200 receive complimentary Priority Dispatch.
Are these compounds sold for human or veterinary consumption?
No. All products listed on PEPTYZ are strictly synthesized and supplied for in-vitro laboratory research, calibration, and analytical assays. None are formulated, packaged, or sold for human or animal administration.
