How we score
- UKPeptideRating/Trustpilot/ML Score: One overall score /10, calculated from the existing recorded Trustpilot stars and reported review count plus approved site reviews, which publish automatically. Site reviews (1–5 stars for experience and quality) each add one review and their average is converted to /10. The public review count includes the recorded Trustpilot count and published site reviews when the Trustpilot numbers are usable.
- Fallback: Where the recorded Trustpilot rating or review count is not a usable number, the original editorial overall score is kept as a 10-review-weight baseline, and only genuine submitted site reviews are included in the public count. No live Trustpilot feed or ML model is claimed.
