B7-33
Research Peptide | Lyophilized Powder | Batch Tested
For laboratory research use only. Not for human or animal consumption. Insulated shipping · Styrofoam box available.
Product Overview
B7-33 is a single-chain peptide analog of the hormone relaxin (H2 relaxin), simplified from the native two-chain structure while retaining receptor activity. It is studied primarily for anti-fibrotic signaling and as a more manufacturable relaxin research tool.

Product & documentation questions
How do I read the size and pack quantity?
The per-vial size and number of vials per pack are listed separately in the table. The displayed price is for one pack. A blend’s stated size can describe combined ingredients; check its product label and report for individual components.
How do I find the matching COA?
Match the product, SKU and batch number with the published report. Open the batch page to read the actual results, original report and laboratory verification link. Ask support to confirm the allocated batch if it is not on your order.
Does a purity result mean every test passed?
No. Identity, purity, fill and endotoxin are separate measurements. Read each reported result and unit. An absent result is not a pass, and a less-than result is not zero.
Research Information
B7-33 is used to investigate biased signaling at the relaxin receptor RXFP1 and its effects on collagen turnover, matrix remodeling and fibrosis in cell and animal models of cardiac, renal and pulmonary tissue. Its simplified structure lets researchers probe relaxin biology without the complexity of the native hormone. Supplied strictly for in-vitro and laboratory research use only — not for human or animal consumption.
