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
Whey Protein Peptide is a hydrolysed peptide from Bovine whey protein, not the intact protein and not a botanical extract of the same raw material. Compare source, degree of hydrolysis and MW distribution when substituting.
Compare these related grades before approval:
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.

Frequently Asked Questions
What specification defines Whey Protein Peptide Powder?
For Whey Protein Peptide Powder: Protein >=80.0% on dried basis; molecular weight mainly below 3,000 Da, tested by HPLC.
Which identity details must remain consistent?
For Whey Protein Peptide Powder: match Bovine whey protein and plant part Hydrolysed whey protein peptide across the quotation, specification and offered-batch COA. The offered grade is Protein >=80.0% on dried basis; molecular weight mainly below 3,000 Da.
How is batch-specific approval completed?
For Whey Protein Peptide Powder: the page cites representative batch LXRQ260128. Final approval requires the current lot’s identity, specification results and relevant dates.
What forms part of the technical review?
For Whey Protein Peptide Powder: do not assess Protein >=80.0% on dried basis; molecular weight mainly below 3,000 Da in isolation; particle size, moisture or drying data and market-relevant safety limits can also affect acceptance.
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.
Can I request the current batch COA before ordering?
Yes. Request the applicable current or representative COA and compare product identity, method, limits and results before approving a purchase order.
What is the minimum order quantity?
The regular MOQ is typically 1 kg. An evaluation sample of 10-20 g can usually be arranged before a formal order, subject to stock.
Do you support custom specifications or packing?
Alternative assay targets, particle size, packing and private-label requirements can be reviewed case by case, subject to production feasibility and a revised written specification.
