Independent European comparison
A source-led directory for assessing European research-peptide supplier websites. We separate observed facts, supplier claims and unknowns—then publish ranks only when the documented scoring review supports them.
The evidence-backed directory is live.
8 supplier sites now carry a full, source-linked category score. 2 more remain in desk review.
Top-scored suppliers
Full dossiers, category rationale and sources are on each record's page.
The strongest batch-specific COA evidence in this set — a named independent lab verified one product's Certificate of Analysis — alongside a named legal entity and a detailed EU delivery table.
Calculated only from stored category scores.
A fully registered Romanian entity with the largest public COA vault reviewed — 49 reports verified through a third-party lab portal — offset by a young domain and a hidden-WHOIS caution from Scamadviser.
Calculated only from stored category scores.
A real UK company registration and a strong per-vial QR-code batch-traceability mechanism, tempered by a registered address shared by thousands of unrelated companies and an unreviewed checkout/privacy page.
Calculated only from stored category scores.
Kept active and flagged rather than delisted: a strong Dutch Chamber of Commerce and VAT registration sits alongside a substantiated third-party security-vendor warning that is surfaced here rather than buried in the score.
Calculated only from stored category scores.
New listing, replacing EuroLab Peptides: a real named legal entity with a materially safer reputation profile than the supplier it replaces, though the testing-lab identity behind its COA claim is not named.
Calculated only from stored category scores.
2 more sites remain in desk review — see the full directory for provisional positions.
Provisional-position rule: Provisional editorial position — full evidence review pending. This label is not an award, score or independently verified conclusion.
Methodology first
Every material conclusion needs a source, observation date and evidence state. Documentation can support narrow claims; it does not prove safety, legality or suitability for human use.
A PDF or logo is only a starting point. Look for a report identifier, laboratory identity, date, method and an independent verification route.
Product, batch and report references should form a coherent chain. A result for one sample does not automatically describe later stock.
Record the legal entity, address, contact channels, policies and dispatch operator. A European domain or euro price does not prove EU establishment.
Unknowns are not converted into invented facts or automatic failures. They reduce evidence confidence until the relevant check is completed.
Evidence literacy
HPLC and mass-spectrometry records can support specific analytical observations under stated conditions. They do not automatically establish sample provenance, sterility, stability, legal status or suitability for any human use.
Editorial boundary: This publication does not sell peptides or provide dosing, administration, treatment, bodybuilding, weight-loss or anti-ageing guidance.
