Semax vs ARA-290
Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: SEMAX, Heptapeptide SEMAX
A synthetic peptide derived from ACTH (4-10) fragment with added Pro-Gly-Pro sequence. Approved in Russia for stroke and cognitive enhancement. Known for nootropic and neuroprotective effects.
Also: Cibinetide, ARA 290
An 11-amino acid peptide derived from erythropoietin (EPO) that activates the innate repair receptor. Unlike EPO, it has no erythropoietic activity but provides cytoprotective, anti-inflammatory, and tissue-protective effects.
Key Comparison Insights
- Both peptides belong to the Cognitive category, suggesting similar primary applications.
Detailed Comparison
| Attribute | Semax | ARA-290 |
|---|---|---|
| Category | Cognitive | Cognitive |
| FDA Status | Not FDA Approved | Not FDA Approved |
| Clinical Status | Pre I II III IV FDA | Pre I II III IV FDA |
| Mechanism of Action | Semax increases BDNF and NGF expression, modulates dopamine and serotonin systems, and has anti-inflammatory effects in the brain. It enhances neuroplasticity and protects neurons from oxidative stress and excitotoxicity. | ARA-290 selectively activates the innate repair receptor (IRR), a heterodimer of EPOR and CD131 (β common receptor). This receptor is expressed on damaged and inflamed tissues. Activation triggers anti-apoptotic, anti-inflammatory, and tissue-protective pathways without stimulating red blood cell production. |
| Common Dosing | 200-600 mcg intranasal daily 1-3x daily, intranasal | 4 mg daily Once daily |
| Administration | Intranasal spray (most common) | Subcutaneous injection |
| Typical Duration | 10-30 days typical | 28-day courses in trials |
| Best Time to Take | Morning or early afternoon | Consistent daily timing |
Possible Side Effects May vary by individual |

|
| Research Summary | Russian research shows cognitive enhancement, improved memory and attention, and benefits for stroke recovery. Studies demonstrate increased BDNF levels and neuroprotective effects. Used clinically in Russia for stroke, TBI, and cognitive disorders. | Phase II/III clinical trials for diabetic neuropathy show improvement in corneal nerve fiber density and small fiber function. Orphan Drug Designation granted in both US and EU for sarcoidosis treatment. Studies demonstrate efficacy in small fiber neuropathy, neuropathic pain, and sarcoidosis-related symptoms. Being developed by Araim Pharmaceuticals. |
Frequently Asked Questions: Semax vs ARA-290
What is the difference between Semax and ARA-290?
