Neuromedin U vs Neuropeptide FF

Neuromedin U vs Neuropeptide FF — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

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....

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 ...
