Science
Mechanism of Action
Semax is a synthetic heptapeptide developed in Russia, derived from ACTH (adrenocorticotropic hormone) fragments. It exhibits pronounced nootropic, neuroprotective, and neuroregenerative effects without affecting cortisol levels. It modulates brain-derived neurotrophic factor (BDNF) and serotonin/dopamine systems, enhancing cognitive function, memory consolidation, and attention.
Benefits
Research Benefits
- Enhances memory consolidation and recall
- Improves focus, attention, and mental clarity
- Neuroprotective effects after stroke or ischemia
- Upregulates BDNF (Brain-Derived Neurotrophic Factor)
- Reduces anxiety and improves stress resilience
- Potential ADHD and cognitive decline research applications

Dosage Protocol
Research protocols typically use 300-600mcg daily via intranasal administration, often divided into 2-3 doses. Subcutaneous dosing at 250-500mcg also studied. Cycles of 5-14 days common.

Stability
Storage Guidelines
Store lyophilized powder at -20°C. Reconstituted solution stable at 2-8°C for up to 30 days. Intranasal solutions should be kept refrigerated.
Safety
Safety & Effects
Generally well-tolerated. Some research subjects reported mild irritability, nasal irritation (intranasal route), or sleep disturbances if taken late in the day. No significant cortisol elevation observed.
