About PeptideRankings
Bringing transparency to the peptide supplement market through independent laboratory testing.
Our Mission
PeptideRankings was created to address a critical gap in the peptide supplement industry: the lack of independent verification of product quality. We believe that consumers deserve access to transparent, objective data about the products they purchase.
By aggregating and analyzing publicly available laboratory test results from Janoshik, we provide unbiased rankings that help consumers make informed decisions about which suppliers to trust. Janoshik,
Independent Data

Science-Based
Our rankings are based on quantitative metrics: purity percentages, accuracy measurements, and consistency data.
Community Driven
Our platform is built for the community. Rankings are continuously updated as new test results become available.
