About peptideguide

Independent.
Methodology-first.

PeptideGuide is an independent comparison site for research-peptide vendors. We score every vendor on the same five axes — Testing, Purity, EU-Friendliness, Value, Trust — and name one editor's pick per region. We do not write top-10 listicles. We do not erase flagged vendors. We do not let affiliates buy placement.

The product is a tool for laboratory researchers and serious self-experimenters who already know what a peptide is and need a structured way to choose a credible vendor. Our methodology is public; the recommendation comes after the rubric, not the other way around.
