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
Collagen Peptide Grade B is a hydrolysed bovine-hide collagen grade listed at protein >=90.0% on a dried basis, with molecular weight mainly below 3,000 Da. Compare its declared range and current batch documents with Grades A and A+ rather than relying on the grade label alone.
Compare these related grades before approval:
For a substitution review, compare bovine-hide source, dried-basis protein content, peptide molecular-weight distribution, analytical method and the current offered-batch COA.

Frequently Asked Questions
How is Collagen Peptide Grade B Powder quantified?
By HPLC against the specification figure of Protein >=90.0% on dried basis; molecular weight mainly below 3,000 Da.
Which molecular weight profile applies?
The declared specification is Protein >=90.0% on dried basis; molecular weight mainly below 3,000 Da, and the peptide distribution is reported with the batch.
How does the material behave in your process?
It is supplied as Fine off-white to cream powder at 98% through 80 mesh, so bulk density and flow are confirmed against your process before the first order.
How long can we hold stock before use?
Two years when stored properly from the manufacture date when the pack stays sealed and dry.
How is lot traceability handled?
Each lot keeps batch records and a retained sample, and the certificate for LXJY260414 carries the same batch reference used in the quotation.
Can I get a sample before placing the order?
Yes. An evaluation sample is normally available before a formal order. Sample quantity, courier account and destination are confirmed at the time of request.
Which documents come with the shipment?
Batch COA, specification sheet, agreed third-party testing where required, commercial invoice, packing list, certificate of origin and transport documents. The exact set is confirmed against the product and destination market.
Can you produce to our own specification or packing?
Alternative assay targets, particle size, packing and private-label requirements are reviewed case by case, subject to production feasibility and a revised written specification.
