CGRP vs Neuropeptide FF

CGRP vs Neuropeptide FF — 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...

Neuropeptide FF
Neuropeptide

Neuropeptide FF (NPFF) is an endogenous octapeptide first isolated from bovine brain in 1985 and recognized as a key endogenous anti-opioid system component. NPFF is produced in the hypothalamus, brain stem, and spinal cord and acts on NPFF1 and NPFF2 receptors (GPCRs) to oppose ...
