About PepFare

PepFare is an independent, community-driven price comparison directory and transparency platform for European and international research peptide suppliers.

⚠️ We do not sell anything · Strictly for research purposes

PepFare is solely an informational directory and pricing comparison engine. We do not sell, supply, manufacture, stock, or distribute any chemical substances or peptide products, nor do we take payments or process orders.

All compounds indexed on this website are listed exclusively for in vitro laboratory, analytical, and scientific research purposes only. They are strictly not for human consumption, clinical diagnosis, therapeutic use, veterinary use, or domestic application.

We Only Display Prices

Our scrapers automatically aggregate publicly available catalog prices, vial quantities, and packaging formats from suppliers across Europe and internationally. We normalize every listing into a standard cost-per-milligram (€/mg) metric and display verified coupon discounts so that researchers can evaluate price differences transparently before placing an order.

The Cheapest Vendor Is Not Always the Best — Do Your Own Research (DYOR)

While PepFare ranks listings by lowest price per milligram to highlight market competition, the cheapest vendor is definitely not always the best choice.

In peptide research, product integrity depends heavily on synthesis standards, storage conditions, and vendor reliability:

Independent Purity & Endotoxin Testing: A rock-bottom price is meaningless if the product contains synthesis impurities, sub-potent dosing, or harmful bacterial endotoxins. Always verify that third-party lab testing (e.g. Janoshik, MZ BioLabs, Lab4Tox) is available and that the batch numbers on the certificates match the physical vial labels.
Packaging & Cold-Chain Shipping: Sensitive lyophilized peptides can degrade if shipped in uninsulated bubble mailers during summer heat waves. Reliable suppliers take cold-chain shipping and proper transit protection seriously.
Domestic Dispatch vs. International Customs Risk: Overseas suppliers (such as raw powder manufacturers in China) may offer very low bulk prices, but shipments carry customs seizure risks, long delays, and potential import VAT. European domestic dispatch generally ensures safer, faster delivery.
Vendor Track Record: Check customer reports regarding shipping consistency, correct product labeling, and whether the vendor honors re-ships if packages are lost or damaged in transit.

Always conduct your own research (DYOR) before ordering from any laboratory supplier. Do not choose a vendor solely on price alone.

Vendor Verification & Editorial Reviews

While we track live catalog prices across dozens of suppliers, we currently provide in-depth editorial reviews and audit profiles for a limited number of vendors.

Our review list is actively expanding and grows each week as we audit additional suppliers, verify recent batch testing reports, inspect shipment practices, and collect direct feedback reports from the research community.

Every vendor on PepFare is marked with one of our four verification badges:

—

No Checkmark · DYOR

Do your own research before ordering. We track live prices and catalog items, but a comprehensive editorial review and background audit of this vendor has not yet been completed.

Yellow Checkmark · Checks Out

The vendor checks out, but not personally tested by our team. They maintain verifiable third-party lab testing (e.g. Janoshik reports) and consistent community feedback, but proceed with standard caution and verify batch COAs before ordering.

Green Checkmark · Checked For Us

Checked for us in the last year. Products from this vendor have been directly ordered, physically received, or tested for our team within the past 12 months.

Red Checkmark · Issues Reported

Significant issues or shady practices reported. Failed purity or endotoxin specifications, deceptive marketing, mismatching batch numbers, unlabelled vials, or unresolved community complaints have been identified. Specific findings are detailed in their vendor audit overview.

How to Inspect Vendor Audit Details

Clicking on any vendor name, checkmark badge, or info button (i) throughout PepFare opens an interactive Vendor Overview drawer. There you can inspect:

Dispatch Origin & Warehouse: Warehouse locations and domestic origin flags (e.g. 🇩🇪 Germany, 🇱🇹 Lithuania, 🇵🇱 Poland, 🇨🇳 China).
Shipping Rates & Methods: Tracked domestic delivery, courier options, and estimated EU transit costs.
Accepted Payment Methods: Credit/Debit cards, SEPA bank transfers, and cryptocurrencies (hover over payment icons for specific processing notes).
Testing Scope & Laboratory Reports: Independent COAs, laboratory names (Janoshik, MZ BioLabs, etc.), purity percentages, and endotoxin tests.
Customer Feedback & Verbatim Reviews: Real, cited feedback reports from fellow researchers regarding packaging quality, batch labeling, shipping times, and vendor responses.
