CART Peptide vs Xenopsin

CART Peptide vs Xenopsin — 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...

Xenopsin
Neuropeptide

Xenopsin is an octapeptide originally isolated from the skin of the South African clawed frog Xenopus laevis. It shares structural similarity with the C-terminal portion of neurotensin and activates neurotensin receptors....
