Apelin-13 vs Vasostatin

Apelin-13 vs Vasostatin — 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....

Vasostatin
Cardiovascular Peptide

Vasostatin refers to the N-terminal fragments of chromogranin A (CgA), particularly CgA1-76 (Vasostatin-1) and CgA1-113 (Vasostatin-2), generated by proteolytic processing of the chromogranin A precursor. While catestatin (CgA352-372) is the C-terminal CgA fragment with anti-cate...
