Europe’s Network for Research Chemicals and Peptide Suppliers.
Independent EU supplier directory and price comparison. Compare peptide suppliers in Europe on reliability, quality and service.
A European network bringing researchers, peptide suppliers and research chemical businesses together around clear information, independent information and transparent comparison.
“Working on PeptideCompare and in the research chemicals sector has taught me a great deal about the compounds, the market, and the people behind it.
I’ve met so many creative and ambitious entrepreneurs who continue to inspire me. What stands out is the range: distinctive organisations with strong brands, carefully presented products, and very different ways of building a business.
PeptideCompare is growing with those conversations. I want it to help researchers compare suppliers and information clearly, while making the work behind each organisation more visible.”
Why PeptideCompare exists
PeptideCompare began as an independent source of information about peptide suppliers in Europe. It now connects supplier discovery and price comparison across the wider research chemicals market.
We bring suppliers into view, compare available information and prices, and get to know the people behind their businesses through real orders, direct contact and products. Our assessments remain independent. The aim is to make quality, reliability and service easier to compare.
Four levels of certainty
We place a real order or receive product samples directly from the supplier — and through that ongoing contact, we look closely at delivery time, packaging, labelling, customer care and invoice details. Earned through a real relationship, never purchased.
We check that a Certificate of Analysis from an accredited independent lab is on file, and that it isn't older than 12 months. Nothing more, nothing less.
This exact product and batch are independently assessed for reconstitution behaviour, appearance, and 28-day refrigerated stability. Our highest trust level — currently limited to select products.
Awarded to suppliers who publish batch-specific COAs covering the full analytical panel via an accredited independent lab (Liquilabs or equivalent): identity (HPLC + MS), purity ≥99.8%, assay content (mg), endotoxins (<0.001 EU/mg), microbial safety, and 7 heavy metals (As, Cd, Co, Pb, Ni, Hg, V). Not self-reported — independently cross-referenced per batch.
