Cerebrolysin vs PACAP-38

Cerebrolysin vs PACAP-38 — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Cerebrolysin
Neuropeptides & Cognition

Cerebrolysin is a heterogeneous neuropeptide complex derived from enzymatic hydrolysis of purified porcine brain cortex proteins. Approximately 25% of the preparation consists of low molecular weight peptides (under 10 kDa) that cross the blood-brain barrier, with the remainder b...

PACAP-38
Neuropeptides & Cognition

Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP-38) is a 38-amino-acid member of the VIP/secretin/glucagon superfamily, first isolated from ovine hypothalamus in 1989 by Miyata and colleagues based on its ability to stimulate adenylate cyclase in pituitary cells. PACAP-...
