Is cortexin a single peptide?

No. Cortexin is a complex mixture of low-molecular-weight polypeptides (up to 10 kDa), amino acids, vitamins, and trace minerals extracted from bovine/porcine cerebral cortex. This multi-component nature distinguishes it from single-sequence peptides.

How does cortexin compare to cerebrolysin?

Both are animal-derived brain peptide preparations. Cerebrolysin is derived from porcine brain and has more extensive Western clinical trial data including large stroke trials. Cortexin is derived from cerebral cortex specifically and has broader Russian clinical use. Preclinical comparisons show similar efficacy.

It has been used clinically in Russia since 1999 with a generally favorable safety record. However, no Western-standard comprehensive safety assessment exists. The animal-derived nature raises theoretical prion concerns, and allergic reactions are possible.

What is the recommended dose range for Cortexin?

The research dose range is 10 mg IM daily (standard Russian clinical protocol), administered via Intramuscular injection, Once daily.
