THE SCARLESS HEALER
Relaxin-2 analog B7-33
B7-33 is an engineered version of relaxin-2, a hormone that prevents tissue scarring. It works by stopping fibroblasts from depositing excess collagen and scar tissue. Unlike natural relaxin, B7-33 provides the anti-fibrotic benefits without causing significant blood pressure drops, making it safer for long-term use.
