Peptide Koning operates an EU storefront offering peptides with linked certificates that were not readable in this evaluation.
Peptide Koning offers research peptides shipped within the EU and accepts card payments, PayPal, and European payment methods. Support is provided via WhatsApp and Telegram. The site hosts a dedicated lab results page with batch codes claiming testing for purity, endotoxins, and heavy metals; however, no certificate files were readable in this check to verify third-party lab names or quantitative results. No physical business address or legal entity details are published.

We could read most of what matters, lab evidence included.
Mixed. Below the median of the 124 research suppliers we have scored (6.0).
- Strong8.0 – 10
- Good6.5 – 7.9
- Mixed5.0 – 6.4
- Weak0 – 4.9
- 1Certificate of Analysis PDF documents could not be opened to confirm testing laboratory identity or lot details.
- 2No physical address or named corporate entity is provided on the storefront.
Third-party test reports: are they recent, lot-linked, and do they use methods that can actually prove identity and amount?
- Published test reportsFlagged
We found no certificates anywhere we could read on the site — no files, and no scans on the pages we opened. For a research-use seller this is the single most important thing to publish.
- Reports tied to a lotNot visible
No documents to trace back to a batch.
- What the reports sayNot visible
The vendor lists certificates of analysis on a lab results page, but no external certificate documents were opened or read.
- Analytical methodNot visible
The vendor claims HPLC testing for purity, along with endotoxin and heavy metal testing, but specific method details were not verified from certificate documents.
- Named third-party labNot visible
No outside laboratory is named. In-house numbers are not independent evidence.
- Document recencyNot visible
The documents carry no date we could read.
Third-party ratings and public threads, read directly at the moment of this check. They are easy to buy and easy to brigade, so they are weighted low and can never overturn a lab-evidence flag. Every source below is also logged in the evidence trail.
Trustpilot did not answer, so we treat their reputation there as not visible.

The score is a weighted mean over the pillars we could actually read — 88% of the model on this run. Anything we could not see is left out of the maths rather than counted against the seller.

Reputation is deliberately the lightest pillar. Even a perfect rating cannot lift a report over a lab-evidence flag.
