RankPeptide is a science-first peptide intelligence platform built for researchers, health professionals, and informed consumers who want objective, evidence-based information about peptide compounds.
We launched in 2026 to address a gap in the peptide information landscape: most peptide content online is produced by suppliers or affiliates with a financial incentive to overstate benefits and understate risks. RankPeptide takes the opposite approach — every claim is graded by evidence strength, and every peptide is assessed through our four-tier evidence system.
The RankPeptide Research Team compiles, verifies, and publishes all content on this platform. Our editorial process requires that every factual claim references a specific peer-reviewed study, clinical trial, or official regulatory document. We do not publish anecdotal evidence as fact, and we clearly label the evidence tier (Tier 1: FDA-approved through Tier 4: early research) for every compound we cover.
RankPeptide earns revenue through affiliate partnerships with peptide suppliers. When you click a supplier link on our site and make a purchase, we may earn a commission at no additional cost to you. All affiliate links are clearly disclosed and use rel="nofollow sponsored" attributes as required by search engine guidelines.
Our affiliate relationships do not influence our editorial content, evidence grading, or supplier rankings. Suppliers cannot pay for higher rankings. Our rankings are determined by independently verifiable criteria: third-party COA availability, HPLC purity testing, shipping reliability, pricing transparency, and community reputation.
Evidence-first methodology. Every peptide on RankPeptide is graded using our 4-tier evidence system based on the strength of published clinical data — not marketing claims or anecdotal reports.
Transparent sourcing. Every factual claim in our articles links to its source — PubMed, DOI, or official regulatory documents. You can verify everything we say.
No medical claims. Peptides discussed on this platform are research compounds or, where indicated, FDA-approved medications. We do not provide medical advice, diagnosis, or treatment recommendations.
Independent supplier verification. We verify supplier COAs, test shipping reliability, and audit affiliate links on a regular schedule. Suppliers that fail our quality checks are removed from our recommendations.
