4 pieces tagged sourcing.
- Sourcing and provenanceWhere research peptides are made, and what USA-made meansMost research peptides are synthesized by contract manufacturers, many of them in China, some in Europe and the United States. What each step of the chain is, what a 'USA-made' label can legally mean, and what a chain-of-custody record should contain.
- Sourcing and provenancePeptide purity grades, salt exchange and modificationsThe grade ladder from crude to 98 per cent and what each is used for, what a salt exchange adds to price and lead time, and the modifications a custom order can specify.
- Sourcing and provenanceHow to vet a peptide vendor with documents, not with forumsA document-by-document checklist for judging a research peptide supplier: lot-specific certificates, identity as well as purity, net peptide content, a named manufacturer and a verifiable laboratory.
- Sourcing and provenanceCosmetic-grade vs research-grade peptidesWhat an INCI name is and who assigns it, what documents a cosmetic formulator needs from an ingredient supplier, and why a vial labelled research use only is not a cosmetic raw material.
