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
Soft-Shell Turtle Peptide is a hydrolysed peptide from Pelodiscus sinensis, 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 long can we hold stock before use?
Two years when stored properly from the manufacture date when the pack stays sealed and dry.
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 LXJY260217 carry through from quotation to certificate.
Which test method should our QC lab expect to reproduce?
HPLC, with the reference standard and calculation basis recorded on the batch certificate.
How is protein content expressed?
Protein >=85.0% on dried basis; low-molecular-weight peptide fraction, on the basis stated on the certificate.
Which particle size or presentation applies?
98% through 80 mesh
Are you a manufacturer or a trading company?
