CART Peptide vs Neuropeptide S

CART Peptide vs Neuropeptide S — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

CART Peptide
Neuropeptide

CART (Cocaine- and Amphetamine-Regulated Transcript) peptide is a neuropeptide encoded by the CARTPT gene, named because its mRNA is dramatically upregulated in the striatum by cocaine and amphetamine administration. CART peptide is produced in the arcuate nucleus, nucleus accumb...

Neuropeptide S
Neuropeptide

Neuropeptide S (NPS) is a 20-amino acid peptide discovered in 2004 that acts on the NPS receptor (NPSR1), a Gq/Gs-coupled GPCR with highest expression in amygdala, hypothalamus, and brainstem arousal centers. NPS produces a distinctive combination of simultaneous wakefulness prom...
