EU Supplier Transparency Index
EU research peptide supplier transparency index
Researchers vetting an EU peptide supplier hit the same wall every time: every supplier claims quality, and the public evidence behind it varies. This index scores EU research-peptide sellers on objective, publicly verifiable signals — independent per-batch testing, legal-entity disclosure, EU dispatch, reviews, catalogue transparency, and track record — each linked to a dated source. CertaPeptides is included and scored on exactly the same criteria as everyone else.

Scores out of 100. Hover a cell for its source and last-checked date. Competitor data reflects information published on each supplier's own website; a 'not found' cell means the signal was not publicly visible at the last check, not an allegation.
How we score
Six criteria, 100 points. The weighting reflects how much each signal actually de-risks a purchase for a researcher.
We chose these six criteria and their weights before scoring any supplier, anchored to independent third-party-testing transparency norms (ISO/IEC 17025-style verification). Each competitor cell links to a dated public source on that supplier's own site.
The index is not built to flatter us: on three of the six criteria — independent reviews, catalogue breadth, and years operating — established competitors out-score CertaPeptides, and the table shows it. We lead on the testing and disclosure criteria, and we say plainly where we don't.
CertaPeptides is a reseller (CERTALAB S.R.L.); Janoshik Analytical is the independent laboratory. This page is not affiliated with or endorsed by any brand listed. Signals reflect what was publicly visible on each supplier's own website at the last-checked date and may change.
Frequently asked questions
How is the transparency score calculated?
Each supplier earns points across six pre-registered criteria (100 max): per-batch third-party COAs (30), legal-entity disclosure (10), stated EU dispatch (10), independent review footprint (20), catalogue breadth with batch numbers on product pages (20), and years operating (10). The methodology above lists every weight.
Why does CertaPeptides rank highly?
Because the criteria reward published, independently verifiable per-batch COAs, which CertaPeptides provides through Janoshik Analytical. On other criteria — such as review volume and years operating — several listed suppliers score higher, and the table shows both.
Is this page affiliated with the listed suppliers?
No. It is not affiliated with or endorsed by any brand listed. It compares publicly available, objective signals only.
How current is the data?
Every competitor cell carries a last-checked date and links to the public source it was read from. Suppliers change their sites; we re-check periodically and date each update.
What does 'not found at last check' mean?
It means we looked for that signal on the supplier's own website on the date shown and did not find it published. It is a statement about public disclosure, not an allegation about the supplier.
