Noopept (Also known as GVS-111) is a relatively new Russian nootropic substance, developed in 1992 by Zakusov Institute of Pharmacology. Noopept is a dipeptide drug, which is a combination of non-peptide Piracetam and a fragment of Vasopressin peptide. Pharmacological study of the drug showed its advantages over peptide and non-peptide analogs.   
The developments were done within the idea that some regulatory neuropeptides may have a significant impact on memory and learning process. Unlike Vasopressin, which shows nootropic activity only when delivered to the brain structures, Noopept is active even upon oral administration. It affects memory and learning process, and effective in the treatment of a wide variety of cognitive disorders.  
Pharmacokinetic studies of this Nootropic showed good bioavailability to the brain.   


Studies show that a 20-30mg daily dose of Noopept provides mild stimulating and anxiolytic effect, and also improves attention, memory and cognitive functions. By its anxiolytic action, it can reduce anxiety, irritability, insomnia and affective lability (mood swings). Noopept has a broad spectrum of nootropic action. It improves not only initial memory acquisition and consolidation but also the process of memory recalling, unlike Piracetam.   
Neuroprotective effects of the drug manifested in increasing the resistance of brain tissue to damaging conditions like hypoxia (oxygen deficiency), intoxication, stressful events or traumatic injuries. Studies have shown that Noopept prevents neurodegeneration (the death of neurons) caused by the influence of toxic concentrations of glutamate and active forms of oxygen.    
Noopept also can be considered as BDNF (Brain-derived neurotrophic factor) and NGF (nerve growth factor) supplement. Studies done in rats show that prolonged usage of Noopept does increase BDNF and NGF levels in the hippocampus. Those neurotrophic factors promote growth and survival of neurons and modulate the long-term memory.   
Summing this up, you can expect the following effects of taking Noopept: 
  • Improvement of memory, attention, and cognitive functions.
  • Anti-anxiety effect.
  • Increased brain resistance to stressful conditions.
  • Mild stimulating effect.


Noopept has a complex mechanism of action. The principle of memory-enhancing effect based not on simple cerebral blood flow improvement. Noopept has a direct impact on the synaptic structure, especially at the Hippocampus. The nootropic effect of the drug associated with one of its active metabolites, cyclo-Glycyl-L-Proline. Cycloprolylglycine is an endogenous peptide with anti-amnesic and selective anxiolytic effect. Recent studies show that Cycloprolylglycine can increase BDNF levels and acts as a positive allosteric AMPA modulator, thus having a significant impact on memory and learning.  
In Russian clinical practice, Noopept used as the treatment of various neurodegenerative diseases. The reason for this its wide spectrum of Neuroprotective action.   
  Here are ways how Noopept protects your brain:
  • Activation of endogenous antioxidant systems.
  • Blockage of voltage-dependent calcium and potassium channels.
  • Anti-inflammatory activity.
  • Reduction of glutamate release.
  • Increasing the level of antibodies to beta-amyloid and decreasing its toxicity. Beta-amyloid is a peptide that is involved in the development of Alzheimer’s disease. It is toxic to the nerve cells.


The most frequent reported side effect is a headache, which usually is a result of poor Choline intake. This side effect can be overcome with Choline supplementation. You can either take choline supplement like Alpha-GPC, CDP-choline, and Choline Bitartrate or eat a choline-rich diet. Eggs, liver, fish, and nuts are high in choline.   
Less frequent and noticeable side effect is an increased blood pressure. If you suffer from hypertension, you should use Noopept cautiously.  
The least possible side effects are anxiety and dizziness. Some people who take Noopept before bed experience insomnia. This is why it should be taken not later than 6 PM.  

Most people, however, don’t experience any side effects. But you should know about possible difficulties when taking this Nootropic. The responsible usage is the key to the satisfying results.  
The Ability of Noopept to be metabolized to endogenous substances (substances that produce naturally in the body) is the main reason of its low toxicity and high therapeutic index.   
The therapeutic index is the ratio between the lethal dosage and effective dosage. A safer drug has a higher therapeutic index. TI for Piracetam is 60, while TI for Noopept is 10.000. Such low toxicity determines the possibility of long-term usage with less risk of side effects.  


Noopept is a very effective Nootropic for memory. It can increase your concentration and improve your cognitive functions as well. Besides that, some people may experience the stimulating and anxiolytic effect.   
This Nootropic has higher bioavailability compared to Piracetam, and significantly less effective dosage. Low toxicity and abuse potential allow long-term usage of Noopept.   
Some people experience side-effects. For someone, the benefits of Noopept overweight it, for some people not. So the best way to test how your body responds to this substance is to start with the small dosages. Just like with any Nootropic or any other supplement.   
The benefits of Noopept  
  • Strong Nootropic effect. Significantly improves memory processing and recall, concentration and cognitive functions.
  • A wide range of Neuroprotective action.
  • Small therapeutic dosage, particularly in the intranasal administration.
  • Low toxicity (20 times higher therapeutic index than Piracetam).
  • May used long-term.
The downside  
  • It may be difficult to dose such little amount of powder precisely. Having a pocket scales or taking capsulated version makes everything easier.
  • Extremely bitter taste. It’s even more noticeable during sublingual usage of Noopept. And again, capsules are a solution.
  • Side effects. They are rare but possible.
