🚩 On the watch list, its certificate can't be verified in its own name.
Tidelabs claims an 'accredited' or 'UKAS-verified UK laboratory' but never names it. Accreditation you can't attribute to a named body is unfalsifiable, the word 'accredited' is doing PR work with nothing checkable behind it. (Note: Janoshik isn't even UK-based, so 'UK lab' is a tell it isn't them.)
What doesn't add up on its site
Quoted straight from tidelabs.co.uk, and why it falls apart.
“…stock lab/pipette photos…”
It dresses the site up to LOOK tested, stock lab/pipette photos, but publishes no real laboratory certificate you can verify. That is the appearance of certification with none of the substance: props, not proof.

Reviews
4.4★★★★☆ · 16 reviews on Trustpilot
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.
The bottom line. Tidelabs sits on the watch list because it does not publish a certificate that can be verified in its own name. Everything above is observable on its own website and the public record. See the vendors whose certificates are actually their own →
