Buy B7-33 6mg Peptide for Fibrosis and Cardiovascular Research with Discreet Worldwide Shipping
What is B7-33 6mg?
B7-33 is a synthetic single-chain peptide analogue derived from the human relaxin-2 hormone, designed to selectively activate the RXFP1 receptor pathway.
Unlike full-length relaxin, B7-33 was developed to retain beneficial antifibrotic and cardioprotective effects without stimulating undesirable vasodilatory responses.
Each vial of B7-33 6mg from Peptide Online Store contains a ≥98% pure, research-grade peptide, ideal for scientific exploration in cardiovascular and fibrotic disease models.
For laboratory research use only — not for human or veterinary administration.
How B7-33 Works in the Body (Research Overview)
B7-33 acts by selectively targeting the relaxin family peptide receptor 1 (RXFP1).
This interaction may promote:
-
Reduction in fibrosis and tissue scarring through modulation of TGF-β signaling
-
Improved cardiac and vascular function
-
Decreased collagen deposition in experimental fibrosis models
-
Cytoprotective effects in endothelial and fibroblast cells
-
Enhanced nitric oxide balance without causing hypotension
Research suggests that B7-33 may represent a next-generation relaxin mimetic for studies exploring fibrosis reversal, heart failure models, and organ repair.
