Typical dose

A single-chain peptide analog of relaxin (H2) studied for anti-fibrotic effects in heart, lung and kidney research.
Mechanism of action
Functionally selective agonism of the RXFP1 relaxin receptor, biasing toward anti-fibrotic ERK signaling.
Research peptide — not approved. Like relaxin it is short-acting; human PK is not established, so the half-life here is an estimate.
