Urocortin vs Vasostatin

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

Urocortin
Cardiovascular Peptide

Urocortin 1 (UCN1) is a 40-amino acid peptide belonging to the corticotropin-releasing factor (CRF) family. While sharing structural homology with CRF, UCN1 binds with higher affinity to CRF receptor type 2 (CRFR2), which predominates in the heart, skeletal muscle, and peripheral...

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...
