I found a batch-specific MOTS-C COA for the listed product size family, with 99.79% purity, measured content 12.07 mg, and an independent lab identity/purity method using HPLC-UV + LC-MS. No sterility/endotoxin or contaminant panels were shown, and I did not see a chromatogram image in the page text.
