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
Fish Bone Collagen Peptide is a hydrolysed peptide from fish bone collagen. Compare the bone source, protein content and peptide molecular-weight distribution with skin-derived fish collagen grades before substitution.
Compare these related grades before approval:
For a substitution review, compare marine species or source tissue, protein content, peptide molecular-weight distribution, analytical method and the current offered-batch COA.

Frequently Asked Questions
Can the COA be matched to the lot you ship?
Yes. The certificate is issued for the shipped lot, which is the batch LXYG260322 referenced on the specification.
Which test method should our QC lab expect to reproduce?
HPLC, with the reference standard and calculation basis recorded on the batch certificate.
Which molecular weight profile applies?
The declared specification is Protein >=88.0% on dried basis; low-molecular-weight peptide fraction, and the peptide distribution is reported with the batch.
How is appearance checked?
Fine off-white to cream powder, compared against a retained sample from the approved batch.
Which safety parameters are tested every lot?
Moisture <=5.0%; result 3.20%, ash <=5.0%; result 3.70%, heavy metals and microbiology against the approved specification.
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.
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.
What is the usual lead time?
Regular production normally takes 7-15 working days after deposit, depending on stock, volume, testing and customisation requirements.
