Semax
Semax
Also known as: SEMAX, Heptapeptide Semax, MEHFPGP
Overview
Key Facts
Primary Goal: Research and therapeutic applications of Semax
Increases BDNF and trkB receptor expression in the hippocampus and cortex. Modulates dopaminergic, serotonergic, and noradrenergic neurotransmission.
Dosing Information
~3-5 minutes (active metabolites persist longer)
200–600 mcg
1-3 times daily
10-30 days (per Russian clinical protocols)
Benefits
- Significant upregulation of BDNF and NGF expression
- Enhanced attention, memory formation, and learning capacity
- Neuroprotective effects against oxidative stress and ischemia
- Reduced anxiety without sedation
- Improved cognitive performance under stress
- Potential stroke recovery support
Side Effects
Mechanism of Action
Increases BDNF and trkB receptor expression in the hippocampus and cortex
Modulates dopaminergic, serotonergic, and noradrenergic neurotransmission
Inhibits enkephalinase activity, prolonging endogenous enkephalin signaling
Melanocortin receptor (MC3/MC4) activation contributes to neuroprotective and anti-inflammatory effects
Contraindications
Do not use this peptide if any of the following apply:
- Active seizure disorders (may lower seizure threshold in susceptible individuals)
- Pregnancy or breastfeeding
- Known hypersensitivity to ACTH-derived peptides
Storage & Reconstitution
Unreconstituted (Powder)
Reconstituted (Mixed)
Research Summary
Semax has been approved in Russia and several CIS countries since 1994 for conditions including stroke recovery, cognitive impairment, and optic nerve atrophy. Russian clinical trials demonstrated improved cognitive scores in post-stroke patients and enhanced memory in healthy volunteers. Research shows robust BDNF upregulation (2-4 fold increases in hippocampal tissue) and significant neuroprotection in ischemia models. It is one of the most well-studied nootropic peptides globally, though it lacks Western regulatory trials.
