Analytical Quality and Documentation
Bluewell Peptides reports HPLC-tested purity above 99.1% and states that a Certificate of Analysis (COA) is provided. Confirm these claims against the documentation for the specific batch.
When reviewing a COA, check the product and batch identifiers, analytical method, reported result, and date of testing. HPLC purity is a method-dependent analytical result; it does not independently establish every aspect of product identity, sterility, or suitability for a particular application.
Product Form and Storage
PT-141 is listed in lyophilised form. Follow the storage conditions stated on the product label and in the applicable stability documentation. The supplier’s proposed storage condition is −20°C in a dry, dark location, with exposure to repeated freeze–thaw cycles avoided where applicable.
Do not assume a shelf life, post-opening stability period, or other storage guarantee unless supported by product-specific data.
