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
Ejiao Peptide is a hydrolysed peptide from Equus asinus hide gelatin (Ejiao), 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
How is protein content expressed?
Protein >=85.0% on dried basis; low-molecular-weight peptide fraction, on the basis stated on the certificate.
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 LXEJ260602 carry through from quotation to 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.
How does the material behave in your process?
It is supplied as Fine light-yellow powder at 98% through 80 mesh, so bulk density and flow are confirmed against your process before the first order.
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.
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 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 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.
