- We have tracked Peptide Kliniek since Sep 2026 and follow 32 of their products, covering 25 peptides. Prices run from €24.95 to €79.95.
- We hold 39 lab certificates from their website, naming RC Testing. We found 0 of the 39 on the issuing lab's own website (not every lab has a public lookup).
- 22 of the 25 peptides we track have a matching certificate from an independent lab (any size counts).
- 0 of the 39 certificates include a contamination test (endotoxin, sterility or heavy metals).
- We have not lab-tested a product from them ourselves yet.
Check it yourself: open a certificate in the product table, find the report number or QR code on it, and look it up on the testing lab's own website. How to read and check a COA.
Why this score
The points for lab testing, reviews, community and transparency, and where each one comes from.
Peptide Kliniek sits at 24 out of 60. Middling. Most of the gap is reviews.
We have not lab-tested anything from them yet, so the 40 points for Lab Verification are off the table for now. What you see is built from three public signals.
We found no review record for them on the platforms we monitor.
Forum and Reddit talk is thin or cautious. Nobody has posted a verified review on PeptideScanner yet, so this rests on what is said elsewhere.
They say they provide third-party certificates of analysis. Of the certificates we list, 31 of 31 dated ones were issued in the last 6 months.
Their own certificates against their claims: 0 of 35 certificates fall below 98% purity. That earns 6.5 of the 10 points for matching claims.
We watch 32 of their products. Prices last checked 16 Oct 2026.
Every line comes from the data we hold on this supplier, nothing is written by hand. How our scoring works
COA availability
The supplier's own published certificate is their statement. Our independent lab result is ours. We never merge the two.
- Peptides with a lab certificate
- 22 of 2588%
Of the 25 peptides in the table below, each counted once whatever the size. The certificate must come from an independent lab and test the peptide itself.
- Found on the lab's own website
- 0 of 39certificates
We look each certificate up with the lab that issued it, where the lab has a public lookup. Many labs have none, so a low number is not a bad sign.
- Contamination tests
- 0 of 39certificates
Most certificates test purity only. Endotoxin, sterility and heavy-metal tests are extras a supplier has to order.

Community signals
A summary of public discussion — a sibling signal, distinct from our verdict and our own reviews.
External review profile now verified at source: 4.4/5 from 13 reviews (search-indexed an external review site, 7 Sep 2026; previously recorded as an unverifiable vendor claim). Still no Reddit, forum or editorial coverage — small but real review base.

What the badges mean
We have independently lab-tested products from this supplier. The badge carries the test date and the named lab. Earned and rare — no supplier holds it yet.
Monitored but not yet tested by us — the default state for a supplier we are following. Trust Score capped at 60.
Documented counterfeit or non-delivery signals. Never presented as a recommendation in any sort order.
A published COA is not a badge tier. It is the supplier's own claim, shown separately above — never merged with our independent result.
