B7-33 Nasal Spray
B7-33 is a synthetic single-chain peptide derived from the B-chain of human relaxin-2 (H2 relaxin). It was developed as a linear, water-soluble analogue containing residues 7–29 of the relaxin-2 B-chain together with a C-terminal KRSL extension. Published scientific studies have investigated B7-33 as a ligand of the relaxin family peptide receptor 1 (RXFP1), including its receptor binding and downstream signalling characteristics in cellular and preclinical experimental models.
Direct SARMs supplies B7-33 as a pre-mixed aqueous nasal spray format for laboratory and analytical research. The 15 ml format contains 4 mg of B7-33, while the 30 ml format contains 8 mg. The nasal spray designation describes the physical presentation of the research material and does not establish intranasal bioavailability, biological activity, safety or suitability for administration.
The documentation using HPLC is given in order to evaluate the chromatographic purity and to establish laboratory traceability. When drawing any conclusions about molecular identity or any other properties, these should be based on the analytical methods that are recorded for that particular batch.
B7-33 Nasal Spray is supplied solely as a laboratory research material and is not intended for human or animal consumption or administration, or for diagnostic, therapeutic, clinical or veterinary use.
Benefits of the nasal spray format
1
The dispensing is pre-measured. Each time the spray mechanism is actuated, it releases a constant volume, which allows for repeatable dispensing when carrying out research procedures.
2
Convenient format. Compact spray bottles are straightforward to store, handle, and transport within an appropriate research environment.
3
Ready to use. Unlike lyophilized peptides, which are provided in vials, nasal spray formulations are in liquid form and do not need to be reconstituted before being handled in the laboratory.
4
Protected storage. The bottle protects the formulation by preventing unnecessary handling and exposure to the environment between research procedures.
5
Simple dispensing. The product can be dispensed easily. With an integrated spraying mechanism, it is not necessary to draw the liquid from a vial, offering a simple way to dispense the formulation during research.

Got a question about this B7-33 compound?
B7-33 Nasal Spray is supplied as a pre-mixed aqueous solution, providing the peptide in liquid form rather than as a dry or lyophilised research material.
Direct SARMs supplies B7-33 Nasal Spray in 15 ml and 30 ml formats. The 15 ml format contains 4 mg of B7-33, while the 30 ml format contains 8 mg.
The preparation contains B7-33, a synthetic single-chain peptide derived from the B-chain of human relaxin-2 (H2 relaxin). It was developed by modifying the relaxin-2 B-chain to produce a smaller, water-soluble peptide for experimental investigation.
The main difference is the physical presentation of the research material. B7-33 Nasal Spray contains the peptide in a pre-mixed aqueous solution, whereas a lyophilised preparation contains B7-33 in a dry, freeze-dried form. The nasal presentation itself does not establish intranasal bioavailability or biological effects.
