ARA-290 Nasal Spray

ARA-290, also known as cibinetide or pyroglutamate helix B surface peptide (pHBSP), is a synthetic 11-residue peptide modelled on the three-dimensional structure of the helix B region of erythropoietin (EPO). Published scientific studies have investigated ARA-290 in experimental models involving EPO-derived signalling, the proposed EPOR/CD131 receptor complex, inflammatory pathways and cellular responses to tissue injury. Findings from these studies relate to the specific experimental models investigated and should not be interpreted as establishing effects associated with the nasal spray format.

Direct SARMs supplies ARA-290 as a pre-mixed aqueous nasal spray format for laboratory and analytical research. The 15 ml format contains 2 mg of ARA-290, while the 30 ml format contains 4 mg. The nasal spray designation describes the physical presentation of the material and does not establish intranasal bioavailability, biological activity, safety or suitability for administration.

Documentation includes a Certificate of Analysis (COA) and HPLC report. It is provided to support assessment of the stated product specifications, chromatographic purity and laboratory traceability.

ARA-290 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

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.

Convenient format. Compact spray bottles are straightforward to store, handle, and transport within an appropriate research environment.

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.

Protected storage. The bottle protects the formulation by preventing unnecessary handling and exposure to the environment between research procedures.

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 ARA-290 compound?

What physical form is ARA-290 Nasal Spray supplied in?

ARA-290 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.

What sizes of ARA-290 Nasal Spray are available?

Direct SARMs supplies ARA-290 Nasal Spray in 15 ml and 30 ml formats. The 15 ml format contains 2 mg of ARA-290, while the 30 ml format contains 4 mg.

What peptide is contained in ARA-290 Nasal Spray?

The preparation contains ARA-290, also known as cibinetide or pyroglutamate helix B surface peptide (pHBSP). It is a synthetic 11-residue peptide modelled on the three-dimensional structure of the helix B region of erythropoietin (EPO).

How does the nasal spray format differ from lyophilised ARA-290?

The distinction relates primarily to the physical presentation of the research material. The nasal spray contains ARA-290 in a pre-mixed liquid solution, whereas lyophilised ARA-290 is supplied as a dry, freeze-dried material.

What analytical documentation is available for ARA-290 Nasal Spray?

Documentation includes a Certificate of Analysis (COA) and HPLC report. HPLC data can provide information about chromatographic purity, while conclusions concerning molecular identity and other specifications should reflect the analytical methods documented for the individual batch.
