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
Spleen Peptide is a hydrolysed peptide from Mammalian spleen, not the intact protein and not a botanical extract of the same raw material. Compare source, degree of hydrolysis and MW distribution when substituting.
Compare these related grades before approval:
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.

Frequently Asked Questions
How is appearance checked?
Fine tan to reddish-brown powder, compared against a retained sample from the approved 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.
What links the quotation to the delivered material?
The specification figure (Protein >=80.0% on dried basis; low-molecular-weight peptide fraction) and the batch number LXPT260617 carry through from quotation to certificate.
How is Spleen Peptide Powder quantified?
By HPLC against the specification figure of Protein >=80.0% on dried basis; low-molecular-weight peptide fraction.
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.
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.
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.
