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
Elastin Peptide is a hydrolysed peptide from bovine ligament elastin, listed at protein >=85.0% on a dried basis. Its source protein differs from collagen and eggshell membrane peptides; compare the current batch specifications before substitution.
Compare these related grades before approval:
For a substitution review, compare animal source tissue, dried-basis protein content, peptide molecular-weight 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.
How does the material behave in your process?
It is supplied as Fine off-white to light-yellow powder at 98% through 80 mesh, so bulk density and flow are confirmed against your process before the first order.
Can the COA be matched to the lot you ship?
Yes. The certificate is issued for the shipped lot, which is the batch LXTX260519 referenced on the specification.
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 specification figure should the purchase order reference for Elastin Peptide Powder?
The figure Protein >=85.0% on dried basis; low-molecular-weight peptide fraction, measured by HPLC.
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 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.
