B7-33 Price Comparison
UK supplier comparison
Use the filters to pick a size and presentation (vial, pen or serum) and compare like for like, or view every size on a £ per mg basis. Delivery is shown separately because it varies by supplier and order size. Offers whose outbound link failed our last check stay listed but rank below working links.

For in-vitro laboratory research only
B7-33 is listed here as a research material. It is not for human or veterinary consumption, and nothing on this page is medical advice or dosing guidance. PeptideCompare is paid by flat supplier fees — never by sales commission or referral — so a price ranks by its number, not by who pays. We do not sell, test or verify any product, and quality or CoA labels are suppliers’ own claims. Always check the final price, documentation and legality with the supplier yourself.
Research profile
About B7-33 in the lab
B7-33 is a short, single-chain peptide derived from the B-chain of human relaxin-2. It was designed to be easier to make than two-chain relaxin and is studied in cardiac, renal and pulmonary fibrosis models.
Proposed mechanism
Acts as a biased agonist at the relaxin receptor RXFP1, favouring pERK signalling over cAMP; this is linked to reduced myofibroblast differentiation and collagen deposition in models.
Typical research themes
- RXFP1 biased agonism
- Myofibroblast models
- Organ fibrosis
