Buyer Decision Guide
Specify Chestnut peptide by the declared basis, the delivered form and the certificate of analysis. For this grade the basis is Purity >=80% and the delivered form is Fine pale cream to light-tan powder. Confirm the destination market requirements, the intended use category and the required documentation before approval. This material is offered as an industrial raw material for further processing, not as a finished consumer product, and no health or medical claim is made.
- Declared basis and delivered form stated on the specification
- Documentation supplied: batch COA, specification sheet and agreed third-party testing
- Species and origin stated on the certificate; substitution requires written confirmation
- Destination market and intended use to be confirmed at quotation stage
- Samples available for evaluation against your own process
How This Grade Differs
Chestnut peptide powder is identified on this page by its Castanea mollissima kernel source and declared purity of at least 80%, assessed with Kjeldahl and SEC-HPLC. A different botanical or algal source, plant part or peptide specification is a separate purchasing choice. Compare the current batch COA and analytical basis before approving a substitute.

Frequently Asked Questions
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 assay does Chestnut Peptide Powder 80% carry on the certificate of analysis?
Assay Purity >=80%, determined by Kjeldahl and SEC-HPLC.
Which safety parameters are tested every lot?
Moisture <=5.0%; result 3.00%, ash <=5.0%; result 3.40%, heavy metals and microbiology against the approved specification.
How does the material behave in your process?
It is supplied as Fine pale cream to light-tan powder at 98% through 80 mesh, so bulk density and flow are confirmed against your process before the first order.
Which molecular weight profile applies?
The declared specification is Purity >=80%, and the peptide distribution is reported with the batch.
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 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.
