Neurotensin vs TLQP-21

Neurotensin vs TLQP-21 — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

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...

TLQP-21
Neuropeptide

TLQP-21 is a 21-amino acid peptide derived from the C-terminal region of VGF (Nerve Growth Factor-Inducible), a large precursor neuropeptide that is proteolytically cleaved into multiple bioactive fragments. VGF is strongly induced by NGF and BDNF and plays roles in energy homeos...
