Adding to Allen’s point, from a Quality Assurance perspective, the definition of a peptide comes down to its size, which we measure in Daltons (Da).
Regular gelatin (partially broken down collagen) has a molecular weight of around 50,000 to 100,000 Daltons. True high-quality hydrolyzed collagen peptides are usually tightly controlled to a molecular weight between 2,000 and 5,000 Daltons. When we receive a batch of raw material, testing that molecular weight is how we verify we actually got peptides and not just expensive gelatin.
