# PeptideCompare.eu > Independent, non-profit price-comparison and encyclopedia for research peptides sold in the European Union. Search 64 compounds across 27 EU suppliers, sorted only by price, purity and independent verification — never by who pays, because no supplier pays for placement or ranking. Available in English, Dutch, German and French. PeptideCompare.eu exists to give researchers a clear, honest, verifiable picture of the EU research-peptide market. All compounds are listed for laboratory research use only; the site sells nothing and gives no dosing or medical advice. Rankings are computed from price (50%), purity (35%) and verification (15%). Three earned verification badges — CMI Verified, COA Verified and Product Verified — are awarded through independent review and can never be bought. Language versions of every page exist under /en/, /nl/, /de/ and /fr/. The English pages are listed below as canonical references. ## Core pages - [Peptide database](https://peptidecompare.eu/en/database/): Compare all 64 research peptides across 27 EU suppliers by price, purity and verification. - [Supplier directory](https://peptidecompare.eu/en/database/suppliers/): EU research-peptide suppliers with verification status and independent test coverage. - [Quality & verification badges](https://peptidecompare.eu/en/kwaliteit/): How the CMI / COA / Product Verified badges are earned and how the ranking is calculated. - [Peptide calculator](https://peptidecompare.eu/en/calculator/): Convert vial strength and BAC water into draw volume and concentration (no dosing advice). - [Reconstitution tools](https://peptidecompare.eu/en/reconstitution/): Reverse calculation and multi-peptide blend planning (no protocols). - [FAQ](https://peptidecompare.eu/en/faq/): Common questions on legality, COAs, badges, ranking and independence. - [About PeptideCompare](https://peptidecompare.eu/en/over-ons/): Non-profit positioning, independence and how the platform operates. ## Encyclopedia & guides - [Encyclopedia index](https://peptidecompare.eu/en/encyclopedia/): 100+ guides covering peptide classes, individual compounds, storage, safety and EU regulation. - [Peptides & EU law, country by country](https://peptidecompare.eu/en/encyclopedia/eu-legal/): What "research use only" means and the legal status of research peptides across the EU27. - [EU customs & research peptides](https://peptidecompare.eu/en/encyclopedia/eu-customs/): How EU customs treats research-peptide shipments, by country. - [Bacteriostatic water guide](https://peptidecompare.eu/en/encyclopedia/bac-water/): BAC water vs sterile water vs saline, and EU sourcing. - [Storage & stability](https://peptidecompare.eu/en/encyclopedia/storage/): Lyophilized vs reconstituted stability, fridge vs freezer. - [Glossary](https://peptidecompare.eu/en/encyclopedia/glossary/): A–Z of every term and abbreviation used on the site. - [Peptide classes](https://peptidecompare.eu/en/encyclopedia/peptide-classes/): Map of GLP-1 agonists, GHRPs, GHRHs, recovery peptides and more. ## Articles & research - [Articles index](https://peptidecompare.eu/en/articles/): Independent write-ups and research summaries. - [What a real COA tells you](https://peptidecompare.eu/en/articles/coa-guide/): How to read a Certificate of Analysis and spot a weak one. - [Compound testing](https://peptidecompare.eu/en/articles/compound-testing/): How independent labs test research peptides (identity, purity, heavy metals, endotoxins). - [Fridge vs. freezer](https://peptidecompare.eu/en/articles/fridge-vs-freezer/): Why lyophilized powder and reconstituted solution need opposite storage rules, and the mechanism behind freeze-thaw damage. ## Notes - Research and educational use only — not for human consumption. Nothing is for sale; no dosing or medical advice is provided. - No paid placement of any kind — price, purity and verification alone determine a supplier's position. - Contact / corrections: https://peptidecompare.eu/en/contact/
