About B7-33
- What it is
- B7-33 is a single-chain analog of the hormone relaxin, simplified from the natural two-chain structure into one linear peptide that still activates the relaxin receptor RXFP1. It is described as a functionally selective agonist that favors pathways reducing tissue scarring. In rodent models of heart and lung disease it reduced organ fibrosis, supporting interest as an anti-fibrotic agent. It has only been studied in preclinical research.
- How it works
- It is a single-chain relaxin analog that selectively activates the RXFP1 receptor, favoring signaling that reduces fibrosis.

Disclosure. Some vendors above are Peptul partners and pay us a commission when you buy through our link. Rows are ordered by: Peptul partners first, then what is in stock, then single vials before multi-vial packs, then price per milligram. Paying us moves a vendor up this order and changes nothing else - not their trust tier, COA badge, Peptul Score or reviews, which come from evidence and are worked out the same way for everyone. Available discount codes are shown beside the prices above. Discounted prices require the displayed code where indicated.
