What a Meaningful Certificate of Analysis Should Include Complete chemical name Declared salt and counterion Free-cation and salt molecular weights where relevant Batch number and manufacture date Observed LC-MS result NMR identity evidence Counterion result Quantitative active-content assay Chromatographic purity Named and unknown impurity results Residual-solvent results Water or loss-on-drying result Elemental or inorganic-impurity testing where appropriate Method references and acceptance limits Testing-laboratory identity A clear statement of tests not performed Why 99% Purity Is Not Enough A single chromatographic percentage does not prove that the main peak is the correct positional isomer, that the counterion is correct, that the quantity is calculated properly or that residual solvents and inorganic impurities meet an appropriate specification
Transport by animals is especially effective, as it allows travel over far distances
How we screen during consultation Every consult begins with a full medical history covering current medications (particularly blood thinners, immunosuppressants, isotretinoin within the last six months), allergies, autoimmune diagnoses, pregnancy or breastfeeding status, prior cosmetic treatments with photos when available, recent dental procedures or planned surgeries, and a detailed goals conversation in your own words
Handling & storage Storage conditions should be read from lot-specific COA/source documents where available, then handled under your laboratory's validated SOP
