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
Yak Bone Collagen Peptide is listed as hydrolysed yak bone collagen, with protein >=90.0% on a dried basis and molecular weight mainly below 3,000 Da. Bone collagen and bone-marrow peptides have different declared source materials; compare current batch specifications before substitution.

Frequently Asked Questions
What do you declare for moisture and ash?
Both are released against the limits on the approved specification; the measured result for your lot appears on its COA.
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 is appearance checked?
Fine off-white to cream powder, compared against a retained sample from the approved batch.
How should the material be stored after arrival?
Two years when stored properly. Keep the pack sealed; moisture uptake is the main risk for this grade.
How recent is the representative batch shown?
The batch referenced is LXMY260306; your shipment is released on its own certificate rather than the representative one.
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.
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.
What is the usual lead time?
Regular production normally takes 7-15 working days after deposit, depending on stock, volume, testing and customisation requirements.
