How This Grade Differs
No grade of this product was listed on the site before this page, so it introduces the product directly. Confirm the grade in the written quotation before the first order.
Quality and Documentation
Released on a batch certificate covering assay or grade, identity, moisture, heavy metals and microbiology.
Frequently Asked Questions
Which test method should our QC lab expect to reproduce?
HPLC, with the reference standard and calculation basis recorded on the batch certificate.
How does the material behave in your process?
It is supplied as 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.
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.
How is lot traceability handled?
Each lot keeps batch records and a retained sample, and the certificate for the shipped lot carries the same batch reference used in the quotation.
How is protein content expressed?
Peptide content 80%, on the basis stated on the certificate.
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.
What is the minimum order quantity?
The regular MOQ is typically 1 kg. An evaluation sample of 10-20 g can usually be arranged before a formal order, subject to stock.
