B7-33 — Benefits, Dosage & Where to Buy
Research Overview
B7-33 is a synthetic single-chain peptide analog of the hormone relaxin-2 (H2 relaxin). It selectively activates the RXFP1 receptor, which mediates anti-fibrotic, vasodilatory, and anti-inflammatory effects. Unlike native relaxin-2, which is a two-chain insulin-like peptide difficult to manufacture, B7-33 is a simplified single-chain structure that retains receptor activity.
B7-33 has demonstrated anti-fibrotic effects in cardiac, renal, and pulmonary fibrosis models - breaking down excess collagen deposition that characterizes fibrotic disease progression.
Key Research Findings
- •Activated RXFP1 with anti-fibrotic, vasodilatory, and anti-inflammatory effects
- •Simplified single-chain structure vs complex two-chain native relaxin
- •Reduced cardiac, renal, and pulmonary fibrosis in animal models
- •Promoted collagen breakdown through MMP upregulation
Research Dosage Protocols
B7-33 is supplied as lyophilized powder. Research is preclinical with doses varying by model system.
