Overview
Peak Performance Peptides runs pppepz.com, which shows a 21+ gate and research-use disclaimer, and its sitemap lists COA, about and terms pages. FDA's letter covers products including retatrutide, semaglutide, SS-31, PT-141 and tesamorelin, and gives a Phoenix, Arizona address. The site loads its content by script, so products, labs and testing could not be confirmed.
