CGRP vs Neuromedin U

CGRP vs Neuromedin U — 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...

Neuromedin U
Neuropeptide

Neuromedin U (NMU) is a neuropeptide first isolated from porcine spinal cord and named for its ability to contract the uterus. Two bioactive forms exist in humans: the shorter NMU-23 and the predominant NMU-25, both C-terminally amidated....
