CGRP vs Neurotensin

CGRP vs Neurotensin — 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...

Neurotensin
Neuropeptide

Neurotensin (NT) is a 13-amino acid neuropeptide widely distributed throughout the central and peripheral nervous systems, with high concentrations in the hypothalamus, nucleus accumbens, and gastrointestinal tract. Discovered in 1973, neurotensin modulates dopaminergic signaling...

Which has a longer half-life, CGRP or Neurotensin?
CGRP half-life: ~7-10 min (plasma; native). Neurotensin half-life: < 5 min (plasma).
Can you stack CGRP and Neurotensin?
CGRP and Neurotensin are in the same category and used together in research protocols. Always consult relevant literature and follow appropriate guidelines.
