🚩 On the watch list, its certificate can't be verified in its own name.
Peptidepro own Janoshik COAs, but it sells GLP-1 'pens' (tirzepatide/retatrutide cartridges), a different, injectable-pen category to research vials.
What doesn't add up on its site
Quoted straight from peptidepro.co.uk, and why it falls apart.
“…a made-up “LAB TESTED” badge…”
It dresses the site up to LOOK tested, a made-up “LAB TESTED” badge, but publishes no real laboratory certificate you can verify. That is the appearance of certification with none of the substance: props, not proof.
Pricing vs the market, benchmarked on BPC-157
BPC-157
£10.9/mg (≈ £109 for a 10 mg vial)
Versus market median (£3.0/mg)
3.6×, very expensive
Far above the market average. 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.
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.
The bottom line. Peptidepro 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 →
