The top UK peptide suppliers on Peptide Scanner, November 2026
Of the 217 UK research peptide shops we score, BluePeak Peptides came first on 4 November 2026, ahead of Wholesale Peptides.
On 4 November 2026 we ranked the 217 research peptide shops we score in the UK. BluePeak Peptides came first, with 33 of 60. Wholesale Peptides came second, also with 33 of 60 once rounded. Those two make up the UK top 1%.
The score adds up three things we can check from outside: lab certificates (25 points), reviews (20) and what people say on forums and Reddit (15). Another 40 points are for our own lab test. We have not lab-tested any shop in this list, so the most they can score today is 60. The typical shop scores 16.
A high rank means a shop has more public proof than others. It does not mean a product is pure, or that everything the shop says is true. Where a shop's own page shows a problem, we list it next to the score. Read the full page before you trust a rank.
No shop pays for its score or its badge. The badge is for November 2026 only. We rank again every month, and a shop can lose it.
