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 Marrow Peptide is listed as sourced from yak bone marrow, with protein >=85.0% on a dried basis. Bone marrow, bone collagen and spinal marrow are different declared source materials; compare current batch specifications before substitution.
Compare these related grades before approval:
For a substitution review, compare the exact declared yak source tissue, dried-basis protein content, peptide specification, analytical method and the current offered-batch COA.

Frequently Asked Questions
How is protein content expressed?
Protein >=85.0% on dried basis; low-molecular-weight peptide fraction, on the basis stated on the certificate.
Is the declared percentage a specification limit or a measured result?
The specification figure is Protein >=85.0% on dried basis; low-molecular-weight peptide fraction; the measured result for your lot is reported separately on its COA.
Can the COA be matched to the lot you ship?
Yes. The certificate is issued for the shipped lot, which is the batch LXMS260611 referenced on the specification.
Which safety parameters are tested every lot?
Moisture <=5.0%; result 4.00%, ash <=5.0%; result 3.50%, heavy metals and microbiology against the approved specification.
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.
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.
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 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.
