Catestatin vs Vasostatin

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

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...

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...
