What the Evidence Score means
It adds up points for what Improved Peptides publicly shows on its own website — lab results, named testing labs, contact details, policies, card payments and independent listings. Each card below shows exactly which checks it passed. A higher score means more you can verify yourself; it is not a safety rating, and ads or affiliate deals never change it. Full method ›
