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 A+ is a hydrolysed bovine-hide collagen grade listed at protein >=92.0% on a dried basis, with molecular weight mainly below 1,000 Da. Compare its declared range and current batch documents with Grades A and B 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
What assay does Collagen Peptide Grade A+ Powder carry on the certificate of analysis?
Assay Protein >=92.0% on dried basis; molecular weight mainly below 1,000 Da, determined by HPLC.
How recent is the representative batch shown?
The batch referenced is LXJY260509; your shipment is released on its own certificate rather than the representative one.
Which molecular weight profile applies?
The declared specification is Protein >=92.0% on dried basis; molecular weight mainly below 1,000 Da, and the peptide distribution is reported with the batch.
What physical form does Collagen Peptide Grade A+ Powder ship in?
Fine white powder with high clarity in solution, supplied as a liquid rather than a milled powder.
Which impurity limits are declared?
Moisture and ash are held within the approved specification limits, with heavy metals and microbiology tested on every lot.
Can I review the COA before I pay?
Yes. Request the current or representative COA and check identity, method, limits and results before approving the purchase order.
What packing options are available?
Standard packing is a sealed food-grade inner liner inside an export carton or fibre drum. Pack size, labelling and private-label artwork are agreed in the written specification.
Are you a manufacturer or a trading company?
LongBio is Shaanxi Longsheng Biotechnology Co., Ltd., a direct manufacturer of botanical extracts and functional ingredients integrating R&D, production and export support. Factory review can be arranged by video or an on-site visit.
