Is a 10 mg catalog size a promise of 10 mg of free peptide?

No. The figure is the catalog size. Net content is a separate line, present only when the lot file states it.

Can the certificate for one size cover another size of the same name?

Not unless the file you opened says so. Keep each milligram size on its own row.

Labeled vial mass versus net content

Labeled vial mass is the milligram size in the catalog name, such as BPC-157 10 mg on the 10 mg listing. That figure tells a purchasing office which fill it is ordering. It is not net peptide content, and it is not the molecular weight from a spectrum. A 10 mg label and a 5 mg label are different lots when each has its own file.

Match the size on the vial to the library row before citing a PDF. The check is in verify a peptide lot against its COA. Cap colour is lot-specific as well. Research-use only.
