Cortexin vs CJC-1295 & Ipamorelin
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 & Ipamorelin
The most popular growth hormone secretagogue combination. CJC-1295 (a GHRH analog) and Ipamorelin (a ghrelin mimetic) work synergistically to stimulate natural growth hormone release with potentially greater effects than either peptide alone.

| Aspect | Cortexin | CJC-1295 & Ipamorelin |
|---|---|---|
| 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 to sustain GH signaling and extend the half-life of growth hormone release. Ipamorelin triggers strong GH pulses by binding to ghrelin receptors. Together, they create both sustained and pulsatile GH release patterns that more closely mimic natural physiology. |
| Typical Dosage | Clinical protocols: 10mg intramuscularly once daily for 10-20 days. May be repeated after 3-6 month interval. | CJC-1295 (no DAC/Mod GRF 1-29): 100-300mcg combined with Ipamorelin 200-300mcg, administered 1-3 times daily. Best results when administered fasted or before sleep. |
| Administration | Intramuscular injection. Comes as lyophilized powder requiring reconstitution. Treatment given in courses rather than continuously. | Subcutaneous injection. Often administered before bedtime to enhance natural nighttime GH release, or in the morning fasted. The combination is typically pre-mixed or injected simultaneously. |
| Side Effects | Generally well-tolerated. May cause injection site reactions or mild allergic responses in sensitive individuals. | Water retention, tingling in extremities, mild headaches, lightheadedness, or increased hunger. Generally well-tolerated with minimal effect on cortisol or prolactin. |
