Direct answer

Is Kensington Labs legit?

Yes. Kensington Labs is an operating United Kingdom research-material storefront rated 8/10. All twelve public Janoshik reports match the laboratory's own records and name the vendor, with ten exact product matches. Reviews.io shows 4.8/5 from 157 reviews. The store offers free tracked UK delivery and takes card, PayPal and Open Banking at checkout. Certificate coverage remains partial: 66 of the vendor's 80 archive rows lead to product tabs with no document.

Evidence summary

Kensington Labs COAs and evidence

Kensington Labs runs a working United Kingdom shop and a certificate page that lists 80 products. Twelve of those entries resolve to Janoshik reports that match the laboratory's own record and name the vendor as the client, so 12 of 12 public reports are verified and ten current product-and-strength rows receive an exact product match.

We rate Kensington Labs 8/10. We set reputation at 8.5 after reviewing the live Reviews.io profile, and operations at 8.5 for free tracked UK delivery and card, PayPal and Open Banking checkout. Certificate coverage is partial because 66 archive links lead to no document, and the store does not publish a legal entity.

Verified Janoshik archive

PeptidePrices reviewed Kensington Labs' 80-row certificate page on September 21, 2026. Fourteen rows link to twelve unique Janoshik reports, and all twelve match the laboratory's official record and name a Kensington client. Every matched report includes identity, purity and measured content; ten current product-and-strength rows have an exact match. The other 66 rows link to a product tab that is absent from the target pages, so they provide no certificate. Two verified reports print no sample strength and remain in the library without a product-row attachment. The GHK-Cu 50 mg report measures 43.36 mg, or 86.7% of its listed amount.

Customer review record

Reviews.io lists Kensington Labs at 4.8/5 from 157 reviews, with 97% recommending the store, as checked October 3, 2026. This is a live customer-review profile linked below. Trustpilot removed its exact-domain profile, so it supplies no current rating. We set the PeptidePrices reputation factor at 8.5/10 after reviewing the Reviews.io record.

Catalog, delivery, and checkout

The catalog has 72 comparable product-and-strength rows, 64 in stock at the September 21 check. Delivery within the United Kingdom is free and tracked. Checkout accepted card through Paytree, PayPal and bank transfer through Fena Open Banking; it required a UK mobile number and postcode. Three £0.00 GLP product pages sent their buttons to another store and were omitted from the price comparison. The store's terms, returns policy and FAQ use different damage-report windows, and two pages state different dispatch cut-offs.

Company disclosure and rating

The storefront publishes support and order email addresses and a one-hour weekday reply target. It does not name a legal entity or company number; its listed London address is in a serviced-office building. We set COA 7.5, reputation 8.5, transparency 7.5 and operations 8.5 on October 3, 2026. Their weighted result is 7.9/10, published as 8/10. Affiliate status carries no score weight.
