About Cerience
Cerience is an independent site that reviews and grades stores selling peptides for research use. We want to make it easy to judge whether a store is legitimate, transparent and reliable before you buy.
We cover the EU market first. Everything discussed here is for laboratory research use only, and we make no medical or therapeutic claims.
How we make money
Stores can pay us for Verified status, where we check their COA, domain and shipping, and for Featured placement. Featured placements are always labelled.
Some links to stores are affiliate links: if you buy after clicking one, the store may pay us a commission. We say so where those links appear.
None of this changes a store’s Cerience Grade or its position in the rankings. We don’t sell peptides.
How grading works
Each store gets a Cerience Grade from A to F. It combines checks we can verify — third-party COAs, HPLC purity, domain age, shipping, payment safety, batch traceability — with community reputation and our own editorial assessment. Serious red flags cap the grade.
