Cortexin vs Synapsin

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

Cortexin
Cognitive & Neurological

Cortexin is a polypeptide complex extracted from the cerebral cortex of pigs (porcine origin) that contains a mixture of low-molecular-weight neuropeptides, amino acids, and protein fractions. It is an approved drug in Russia, used clinically for stroke recovery, traumatic brain ...

Synapsin
Cognitive & Neurological

Synapsin is a proprietary intranasal peptide blend combining GHK-Cu (copper tripeptide for neuroregenerative and anti-inflammatory effects) and Dihexa (a potent HGF/c-Met agonist for synaptogenesis and memory). The combination targets synaptic density and cognitive performance fr...
