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 Spinal Marrow Peptide is listed as sourced from yak spinal marrow, with protein >=85.0% on a dried basis. Its declared source differs from bone-marrow and brain-marrow peptides; 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
What physical form does Yak Spinal Marrow Peptide Powder ship in?
Fine light-yellow powder, milled to 98% through 80 mesh.
What shelf life and storage conditions apply?
Two years when stored properly, kept sealed in a dry place away from light and heat.
What links the quotation to the delivered material?
The specification figure (Protein >=85.0% on dried basis; low-molecular-weight peptide fraction) and the batch number LXMJ260219 carry through from quotation to certificate.
Which impurity limits are declared?
Moisture and ash are held within the approved specification limits, with heavy metals and microbiology tested on every lot.
Which molecular weight profile applies?
The declared specification is Protein >=85.0% on dried basis; low-molecular-weight peptide fraction, and the peptide distribution is reported with the batch.
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.
What is the usual lead time?
Regular production normally takes 7-15 working days after deposit, depending on stock, volume, testing and customisation requirements.
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.
