Purity Testing and Storage
Every lot of Cerebrolysin supplied by Cleared Peptides is tested by an independent laboratory for identity and purity (or composition, for multi-component preparations), and the lot Certificate of Analysis is published on our COA page. Store as directed on the label and lot COA (lyophilized format at −20 °C; solution format refrigerated at 2–8 °C), protected from light. Handle according to your institution’s chemical-hygiene procedures.

Frequently Asked Questions
Why is Cerebrolysin tested by composition?
Because it is a mixture of many peptides and amino acids rather than a single compound.
Is Cerebrolysin for human use?
No. Cleared Peptides supplies Cerebrolysin for laboratory research use only; it is not for human or veterinary use.
