Prestigesciences is a US-based vendor selling peptides for both retail and bulk purchase, with a mid-sized catalogue. About half the products have COA coverage—21 reports averaging 99.76% purity, posted on the vendor's site. Community feedback is extremely limited: a single positive mention of product quality from one source, which isn't enough to form a confident picture of the buyer experience. The site is verified, but broader data on shipping and service remains thin.
