Neuropeptide FF vs Neurotensin

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

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 ...

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...
