CART Peptide vs TLQP-21

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

CART Peptide
Neuropeptide

CART (Cocaine- and Amphetamine-Regulated Transcript) peptide is a neuropeptide encoded by the CARTPT gene, named because its mRNA is dramatically upregulated in the striatum by cocaine and amphetamine administration. CART peptide is produced in the arcuate nucleus, nucleus accumb...

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...
