Apelin-13 vs Catestatin

Apelin-13 vs Catestatin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Apelin-13
Cardiovascular Peptide

Apelin-13 is the most biologically active isoform of the apelin peptide family, endogenous ligands for the APJ receptor (also called APLNR). Apelin peptides are produced throughout the body, with the heart, lung, brain, and adipose tissue expressing particularly high levels....

Catestatin
Cardiovascular Peptide

Catestatin is a 21-amino acid peptide derived from the chromogranin A (CgA) protein, specifically cleaved from the region spanning residues 352-372. It was identified as an endogenous inhibitor of catecholamine secretion, acting as a non-competitive antagonist at nicotinic acetyl...
