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
Marine Fish Oligopeptide is a low-molecular-weight fraction from mixed marine fish protein. Compare the source declaration, protein content and peptide molecular-weight distribution with collagen peptide 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
Which molecular weight profile applies?
The declared specification is Protein >=85.0% on dried basis; molecular weight mainly below 1,000 Da, and the peptide distribution is reported with the batch.
Which impurity limits are declared?
Moisture and ash are held within the approved specification limits, with heavy metals and microbiology tested on every lot.
Which particle size or presentation applies?
98% through 80 mesh
Is the declared percentage a specification limit or a measured result?
The specification figure is Protein >=85.0% on dried basis; molecular weight mainly below 1,000 Da; the measured result for your lot is reported separately on its COA.
How long can we hold stock before use?
Two years when stored properly from the manufacture date when the pack stays sealed and dry.
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.
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.
