The methodology is publicly documented and updated quarterly by our Scientific Advisory Board (six clinical pharmacologists, two regulatory scientists, one biostatistician). Every grade links to its source papers and dissent notes. We accept no money from manufacturers, importers, compounding pharmacies, or telehealth clinics. The encyclopedia is funded by one academic foundation.
Six weeks of port records, supplier interviews and independent assay testing reveal a supply chain hiding in plain sight inside the EU's compounding exemption. We name the importers, the broker, and the compounding pharmacy at the centre.
Independent HPLC-MS testing of 22 products purchased anonymously. Four contained no peptide at all.
