Angiotensin 1-9 vs Vasostatin

Angiotensin 1-9 vs Vasostatin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Angiotensin 1-9
Cardiovascular Peptide

Angiotensin 1-9 (Ang 1-9) is a 9-amino acid peptide formed when ACE2 cleaves the C-terminal leucine from angiotensin I (Ang I, 10 AA). Discovered as part of the counter-regulatory renin-angiotensin system (RAS), Ang 1-9 opposes the hypertensive and tissue-damaging actions of angi...

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...
