CGRP vs CART Peptide

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

CGRP
Neuropeptide

Calcitonin gene-related peptide (CGRP) is a 37-amino acid neuropeptide produced by alternative splicing of the calcitonin gene in neurons. It is the most abundant neuropeptide in the sensory nervous system, expressed in trigeminal ganglion neurons and released from perivascular n...

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...
