Risynth Bio is a site-verified vendor selling both retail and bulk peptides, with a broad catalogue. The vendor hosts its own COAs rather than using a third-party lab; while published tests average around 99.9% purity, they cover less than a fifth of the catalogue, leaving most peptides without visible results. Community feedback is minimal—a single negative mention about product quality from one source—and no pricing information has been observed on the site. The limited testing coverage, absent pricing data, and thin community record make this a harder vendor to evaluate.
