Angiotensin II vs Salusin-Beta

Angiotensin II vs Salusin-Beta — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Angiotensin II
Vasoactive Peptide

Angiotensin II is the principal effector peptide of the renin-angiotensin-aldosterone system (RAAS), a master regulator of blood pressure, fluid balance, and cardiovascular function. Generated by sequential cleavage of angiotensinogen by renin (producing Ang I) then by angiotensi...

Salusin-Beta
Vasoactive Peptide

Salusin-beta is a 20-amino acid vasoactive peptide derived from the TOR2A (torsin family 2 member A) gene, which also encodes the related peptide salusin-alpha (28 aa). Discovered in 2003 by Shichiri et al....
