CGRP vs Neuropeptide S

CGRP vs Neuropeptide S — 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 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...

Which has a longer half-life, CGRP or Neuropeptide S?
CGRP half-life: ~7-10 min (plasma; native). Neuropeptide S half-life: Short (minutes, CNS).
Can you stack CGRP and Neuropeptide S?
CGRP and Neuropeptide S are in the same category and used together in research protocols. Always consult relevant literature and follow appropriate guidelines.
