Supplier ranking FAQ

Top rated peptide supplier questions

How are top rated peptide suppliers ranked?

Suppliers are ranked by average published verified-order rating, then review count, then name. Order counts, fulfilment figures and testing references do not determine this ranking.

Do top rated suppliers include batch-tested products?

Yes. Supplier profiles link to products with public batch testing references where available, including task numbers, reported purity results, tested dates and laboratory reference keys.

Can I compare top suppliers by shipping support?

Yes. Supplier cards include country, fulfilment metrics, response time, shipping methods, destination coverage and supplier profile links for deeper comparison.

Are products from top rated suppliers for human use?

No. Supplier profiles and product listings are intended for research-use sourcing review only and are not sold for human consumption, medical use or self-administration.
