Alternatives to Nupex in the UK: sellers you can actually verify

Nupex (nupex.co.uk) does not publish a certificate of analysis you can verify in its own name. If that is why you are looking for an alternative, the UK sellers further down do, so you can check the testing yourself before you buy. The Peptide Watch takes no vendor money and links to no seller's shop.

Why Nupex is on the watch list

It trades as Research Scientific Ltd (Companies House 16181281, Christchurch) and states its peptides are 'third-party tested' / 'lab tested' to ≥99% but never names the lab and publishes no verifiable certificate, offering a COA only 'where available' on request. A purity claim with no named lab, no published document and no verification link is just a number on a product page, the buyer is asked to take quality entirely on trust.

• Why it is on the watch list: No named lab, nothing to verify
• Shared operator: the same operator also runs researchscientific.co.uk, so comparing Nupex with those is comparing one seller with itself
• Pricing: BPC-157 at £8.95/mg, 200% above the market median, a premium price without the verifiable testing that would justify it
• Advertising: buys Google Ads for peptide search terms, so ranking above the organic results reflects ad spend, not vetting
• Domain: Domain registered Jan 2025 · 1.6 years old
