The certificate

✅ Its certificate is its own. Kensington Labs publishes its own Janoshik certificates, for example test #70793, naming Kensington Labs as both client and manufacturer, verifiable with key GBCLIHVV6XW3. It carries 30+ Janoshik reports; the most recent certificate we verified dates to July 2025, genuine, but older.

🔬 Verify this certificate on Janoshik’s own site →

Opens the report on janoshik.com. Confirm the Client field names Kensingtonlabs and the purity matches. This is exactly the check we ran.

What this certificate actually is: Its own Janoshik certificate, it names the seller as the client and can be verified on Janoshik's website., client field: Kensington labs

⏳ This certificate is dated Jul 2025, 12 months old. A Certificate of Analysis only covers the single batch that was tested. Unless the seller has re-tested since, the stock you'd receive today is unverified, or it has sold the same batch for 12 months, which for a peptide is not credible.

Pricing vs the market, benchmarked on BPC-157

BPC-157	£3/mg (≈ £29.95 for a 10 mg vial)
Versus market median (£3.0/mg)	about the same as the market average (1× the median)

In line with the wider UK market. The Peptide Watch benchmarks every vendor on the same compound, BPC-157, the most common research peptide, as £ per milligram, so prices are directly comparable across all providers.

Google Ads

ℹ️ Note: this seller also runs Google ads for research peptides, a category Google's own policies prohibit, visible in Google's Ads Transparency Centre (UK). Worth knowing, but it doesn't bear on the question that puts it on the independently-tested list: its certificates are its own and genuine.

Reviews

Has a Trustpilot page, but too few reviews for a score.

Read it critically. A Trustpilot score measures whether parcels turn up and support replies, not whether the vial contains what the label says. A vendor can have hundreds of happy delivery reviews and still show you a borrowed or fake certificate; the two are unrelated. Also watch for a burst of near-identical 5-star reviews in a short window, the signature of bought reviews.

Kensingtonlabs reviews: what others report

Third-party signals we found, reviews, independent tests and platform actions, each attributed to its source and labelled by how well it is corroborated. This is not our own verification; items marked "single / unverified report" are unconfirmed and should be treated with caution.

✅ single / unverified report

Several reviewers reference Kensington Labs supplying Janoshik COAs and note the lab results 'are always good to see'. This is customers citing the vendor's published COAs rather than a buyer independently sending product to Janoshik, so it is low confidence as a purity signal.

“Appear genuine with their COA from Janoshik... loads of janoshik lab test results, always good to see.”

Is Kensingtonlabs legit? The questions people ask

Is Kensingtonlabs legit?

On The Peptide Watch's independent audit, Kensingtonlabs (kensingtonlabs.co.uk) publishes its own verifiable Janoshik certificate of analysis that names Kensingtonlabs itself as the client, so its testing can be checked on Janoshik's own website. That is the strongest evidence standard we track. It confirms the credibility of the seller's evidence, not any individual vial you receive.

Can I trust Kensingtonlabs, and is it a good supplier?

Its lab evidence is independently verifiable, which is the best signal a paper trail can give. Even a genuine certificate proves a sample was tested once, not that your specific batch matches it, so weigh it alongside consistent results over time.

Is Kensingtonlabs a scam?

Nothing in this audit indicates that. Kensingtonlabs shows a verifiable own-name Janoshik certificate, the opposite of the borrowed or self-made certificates the watch list flags. Judge it on that checkable evidence rather than the word 'scam'.

Does Kensingtonlabs publish a real Certificate of Analysis?

Yes. Its most recent own-name Janoshik certificate is dated Jul 2025 and can be verified on Janoshik's website by its unique code, so the purity result cannot be faked or edited.

The bottom line. Kensingtonlabs earns a place on the independently-tested list because it pays an independent lab (Janoshik) to test its own stock in its own name, and lets you verify it. That is the standard.
