ARA-290 (Cibinetide) is an 11-amino-acid peptide derived from the tissue-protective region of erythropoietin (EPO). Unlike EPO, it was specifically engineered to provide tissue-protective and anti-inflammatory effects without stimulating red blood cell production.
What researchers study ARA-290 for
- Peripheral neuropathy and small fiber neuropathy
- Nerve regeneration
- Chronic inflammatory conditions
- CRPS (Complex Regional Pain Syndrome)
- Diabetic neuropathy
- Tissue repair and recovery
- Neuroprotection
How it works
ARA-290 activates the Innate Repair Receptor (IRR), a receptor involved in the body’s natural healing response. Activation of this pathway appears to:
- Reduce inflammatory signaling
- Protect cells from damage
- Promote nerve repair and regeneration
- Support tissue healing without increasing hematocrit or red blood cell counts
Why it gets attention for nerve pain
Among research peptides, ARA-290 is one of the most discussed for:
- Burning or tingling nerve pain
- Small fiber neuropathy
- CRPS
- Nerve injury recovery
Clinical studies have shown improvements in neuropathic symptoms and evidence of nerve fiber regeneration in some patients with diabetic and sarcoidosis-related neuropathy.
Potential benefits reported in research
- Reduced neuropathic pain
- Improved nerve fiber density
- Reduced inflammation
- Improved autonomic nerve function
- Potential improvements in metabolic markers in diabetic patients
For someone researching CRPS, neuropathy, numbness, burning sensations, or nerve damage, ARA-290 is one of the most targeted peptides currently being investigated.
EXPERIMENTAL PREPARATION
For accurate research application:
- Reconstitutewith appropriate volume of bacteriostatic water
- Inject BAC water slowly down the inside wall of the vial, rather than directly onto the powder.
- Gently swirluntil fully dissolved (do not vortex)
- Administerimmediately or store at 4°C protected from light
- Reconstituted: Stable 30 days at 4°C
