Documentation first
Product pages should not outrun the available records. COA entries show documentation status by catalog item.
Premium peptides, treated like the real thing.
CellSyntax is a research-material catalog built around conservative product pages, account-gated catalog access, and COA documentation status.
Research catalog, built for researchers.
Many research-material catalogs ask buyers to trust broad product claims. CellSyntax is being built in the opposite direction: material identity, lot documentation, and COA entries first.
All products are research chemicals for in vitro laboratory use only. They are not drugs, dietary supplements, foods, or cosmetics, and are not for human or veterinary use. See Intended Use.

COA review
Buyers can review lot identifiers, method names, dates, issuers, and measured fields when batch documents are posted.
03
Account gated
Catalog, product, and cart pages need a signed-in account with a verified email. The COA library and research library stay public.
