Elabela vs Urocortin

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

Elabela
Cardiovascular Peptide

Elabela (also called Apela or Toddler) is the second endogenous peptide ligand for the APJ receptor, discovered in 2013 independently through two approaches: as an essential zebrafish cardiac development factor (Toddler) and as a novel human APJ ligand (Elabela). Unlike apelin pe...

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...
