Buyer Decision Guide
Peptides are specified by source, degree of hydrolysis and molecular-weight distribution. Confirm the protein content basis, the assay method and the MW cut-off, because two products described by the same name can behave very differently in solubility and taste.
- Confirm the source material declaration
- Check protein content and the assay method
- Review molecular-weight distribution data
- Confirm solubility, taste and hygroscopicity for your format
How This Grade Differs
Shark Cartilage Peptide is a hydrolysed peptide from shark cartilage, listed at protein >=85.0% on a dried basis. Compare the cartilage source, peptide specification and current batch documents with chicken-cartilage or fish-bone grades before substitution.
Compare these related grades before approval:
For a substitution review, compare animal source tissue, dried-basis protein content, peptide molecular-weight specification, analytical method and the current offered-batch COA.
