Class & Mechanism
Semax is a synthetic peptide and a fragment of the adrenocorticotropic hormone (ACTH, ACTH4-10). It exhibits nootropic, psycho-stimulating, antioxidant, and antihypoxic effects. Semax works by elevating the expression of BDNF and the TrkB receptor, activating dopaminergic and serotonergic stems, and attenuating chronic stress effects. It also has potential as a melanocortin antagonist (MC3R, MC4R) [18][24].
Research-documented benefits
– Counteracts inhibition of learning and memory induced by heavy metals [18].
– Inhibits neurodegeneration caused by dopamine oxidation [18].
– Promotes neuron survival during hypoxia and glutamate neurotoxicity [18].
– Increases the amount and mobility of immune cells [18].
– Enhances the expression of chemokine and immunoglobulin genes [18].
General-knowledge benefits
– Semax has been shown to improve memory and cognitive disorders.
– It boosts the immune system and helps treat peptic ulcers.
– The peptide supports the optic nerve and has neuroprotective properties.
Typical injectable protocol
Adult human dose: 750–1000 mcg intranasally, 100–300 mcg Sub Q daily. It is advised not to exceed these maximum dosages to avoid desensitization, and the dose depends on patient response [18].
Key risks / contraindications
– More than the maximum dosages can lead to desensitization [18].
– Semax should be used with caution in individuals with a history of psychiatric disorders or those taking medications that affect neurotransmitter levels.
Bottom line
Semax is a potent cognitive-enhancing and neuroprotective peptide used to treat memory and cognitive disorders, support the immune system, and improve neuronal survival under stress.
