Salusin-Beta vs Sarafotoxin

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

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....

Sarafotoxin
Vasoactive Peptide

Sarafotoxins are a family of 21-amino acid peptides isolated from the venom of the Israeli burrowing asp (Atractaspis engaddensis). They are structural and functional homologs of endothelin-1, sharing ~60% sequence identity and acting on the same ETA/ETB receptor subtypes....
