Plain-language methodology and supplier guides for the UK, US and Germany
The methodology page was rewritten in plain language, and three country guides rank suppliers 70% on trust and 30% on price.
On 1 October 2026 we rewrote our methodology page in plain language. It shows the four parts of the score, how community presence is measured, which certificates count, and worked examples. The scoring itself did not change.
The same day we published supplier guides for the UK, the US and Germany. Each guide ranks suppliers that serve that country, 70% on trust and 30% on price, and gives a short written case for each supplier.
We also published how we grade supplier prices. Each supplier gets a plain-language price grade, worked out by matching peptide strength and pack size before comparing prices.
The guides and the price method are written by Sophie Kitchen, co-founder for verification science.
The three guides are linked from the footer of every page, under UK, US and Germany suppliers.
