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
Calf Thymus Peptide is a hydrolysed peptide from Bos taurus calf thymus, 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
Which molecular weight profile applies?
The declared specification is Protein >=80.0% on dried basis; low-molecular-weight peptide fraction, and the peptide distribution is reported with the batch.
Which safety parameters are tested every lot?
Moisture <=5.0%; result 3.20%, ash <=5.0%; result 3.20%, heavy metals and microbiology against the approved specification.
What assay does Calf Thymus Peptide Powder carry on the certificate of analysis?
Assay Protein >=80.0% on dried basis; low-molecular-weight peptide fraction, determined by HPLC.
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 recent is the representative batch shown?
The batch referenced is LXXN260318; your shipment is released on its own certificate rather than the representative one.
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 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.
How is the material shipped?
Air and sea freight are both arranged, with the mode chosen against volume, destination and required date. Documents and the HS code are issued with the shipping instructions.
