Cortexin vs CJC-1295
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Cortexin
Cortexin is a polypeptide complex derived from pig brain cortex, used clinically in Russia and Eastern Europe for neurological conditions including stroke recovery, traumatic brain injury, and cognitive decline.
Full details →CJC-1295
CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to produce more growth hormone.
Full details →Side-by-Side Comparison
| Aspect | Cortexin | CJC-1295 |
|---|---|---|
| Mechanism | Contains a mixture of neuropeptides and amino acids that support neuronal metabolism, provide neuroprotection, and enhance synaptic transmission. Specific mechanisms not fully characterized. | CJC-1295 binds to GHRH receptors in the pituitary, triggering increased production and release of growth hormone. The DAC (Drug Affinity Complex) version extends half-life significantly. |
| Typical Dosage | Clinical protocols: 10mg intramuscularly once daily for 10-20 days. May be repeated after 3-6 month interval. | CJC-1295 DAC: 1-2mg weekly. CJC-1295 no DAC (Mod GRF 1-29): 100-300mcg 2-3 times daily. |
| Administration | Intramuscular injection. Comes as lyophilized powder requiring reconstitution. Treatment given in courses rather than continuously. | Subcutaneous injection, often combined with a GHRP like Ipamorelin for synergistic effects. Best administered before sleep or fasted. |
| Side Effects | Generally well-tolerated. May cause injection site reactions or mild allergic responses in sensitive individuals. | Water retention, tingling in extremities, potential increase in cortisol and prolactin levels. |
