◇ The Peptide Watch, independent vendor audit

Is Regenlabs legit?

regenlabs.co.uk · audited 1 July 2026
🚩 On the watch list, its certificate can't be verified in its own name.

Regenlabs shows a genuine Janoshik report to look legitimate, but the certificates on display name a rotating cast of unrelated companies as the client, not Regenlabs. In other words it has never paid to test its own stock; it has taken a certificate that proves a sample from its supplier's own line, and presents it as proof of what's in the vial it ships. The buyer is shown real-looking science that is, for their purposes, meaningless, there is no link between that certificate and the product they receive. Aggravating: recycles copy/templates shared with other 'brands'.

🕸 This is one of 2 storefronts run by the same operator. The same people also run: regenpeptides.co.uk. (the same company, Midshire Labs Ltd (formerly Regen Peptides Ltd / Regeneration Labs Ltd), same address.)
"Shopping around" between these names is buying from one seller, same stock, same risk, different branding.

The certificate, and what's wrong with it

Certificate displayed by Regenlabs
What this certificate actually is: Read the client / manufacturer field: it names a different company, a supplier, not this seller. The test is borrowed; it proves a supplier's batch, not this shop's stock.
This certificate is dated Oct 2025, 9 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 9 months, which for a peptide is not credible.

Pricing vs the market, benchmarked on BPC-157

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. No public BPC-157 price feed was available for this vendor at audit.

Reviews

4.5 ★★★★☆ · 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. Regenlabs 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 →
