Why this directory exists
Research supplier claims can be difficult to compare. PepSonar makes the sources, dates and unresolved questions easier to see. The aim is useful context for legitimate research procurement and laboratory-service enquiries.
What you can explore
The directory contains ten research-supplier and custom-synthesis profiles, two testing-laboratory profiles, one separately listed clinical service and six practical guides. Search the directory or compare up to three providers within the same service category. Browsing is free and requires no account.

Evidence with its limits attached
These launch profiles are public-source assessments. No purchase, independent product test, laboratory accreditation check or batch authentication has been performed for them. Each profile identifies its actual scope.
