◇ The Peptide Watch, independent vendor audit

Is Nupex legit?

nupex.co.uk · audited 1 July 2026

🚩 On the watch list, its certificate can't be verified in its own name.

Nupex states its peptides are 'third-party tested' / 'lab tested' to ≥99% but never names the lab and publishes no verifiable certificate. A purity claim with no lab, no document and no verification link is just a number on a product page, the buyer is asked to take quality entirely on trust.

Pricing vs the market, benchmarked on BPC-157

BPC-157	£8.95/mg (≈ £89.45 for a 10 mg vial)
Versus market median (£3.0/mg)	3×, 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.

Google Ads

🚩 Advertising research peptides on Google, a category Google's own policies prohibit. Live ads for this domain are visible in Google's Ads Transparency Centre (UK), see for yourself. Getting banned products through Google's review typically means short-lived or multiple advertiser accounts.

The bottom line. Nupex 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 →
