Noopept (developmental code GVS-111) is a dipeptide nootropic compound developed in Russia in the 1990s as a novel cognitive enhancer with neuroprotective properties. Structurally, it is a cycloprolyl-glycine derivative that shares some pharmacological similarities with racetams (particularly piracetam), but with significantly higher potency—estimated to be approximately 1,000 times more potent than piracetam.
Key : Unlike most nootropics that require weeks to show effects, Noopept has demonstrated rapid onset in research models. It exhibits both cognitive-enhancing and neuroprotective properties, including protection against oxidative stress, excitotoxicity, and ischemia-reperfusion injury. Noopept also increases brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) levels in the hippocampus.
Noopept exerts its effects through multiple pathways, distinguishing it from classic racetams:
| Pathway | Mechanism | Research Finding |
|---|---|---|
| BDNF/NGF upregulation | Increases brain-derived neurotrophic factor and nerve growth factor in hippocampus | Supports synaptic plasticity, neurogenesis |
| AMPA/kainate receptor modulation | Positive allosteric modulation (similar to racetams) | Enhances glutamatergic transmission |
| Neuroprotection | Reduces oxidative stress, inhibits lipid peroxidation, protects against excitotoxicity | Preclinical models of ischemia, traumatic brain injury |
| Cholinergic system | May enhance acetylcholine release (indirect) | Memory and learning support |
| Anti-inflammatory | Reduces neuroinflammation (preclinical) | Neuroprotection |
Noopept has been shown to protect against neurodegeneration in animal models of Alzheimer’s disease, Parkinson’s disease, and cerebral ischemia. It reduces amyloid-β toxicity and may have disease-modifying potential (preclinical only).

Q: Is Noopept the same as Piracetam?
A: No. Noopept is a dipeptide derivative with different chemical structure, significantly higher potency (~1,000x), and distinct mechanisms (including BDNF/NGF upregulation). It is not a racetam, though it shares some pharmacological similarities.
Q: Is Noopept FDA-approved?
A: No. Noopept is not FDA-approved for medical use in the United States. It is available as a research chemical for laboratory use only. It has been used as a prescription medication in Russia.
Q: What is the difference between Noopept and other nootropics?
A: Noopept is unique in its ability to upregulate BDNF and NGF in the hippocampus—a property not shared by classic racetams. It is also significantly more potent (microgram vs. milligram dosing).
Q: What is the primary active metabolite of Noopept?
A: Cycloprolylglycine (CPG). Noopept is rapidly metabolized to CPG, which is believed to contribute significantly to its pharmacological effects.
Q: Does Noopept have neuroprotective properties?
A: Yes. Preclinical studies have demonstrated neuroprotective effects in models of stroke, traumatic brain injury, excitotoxicity, and neurodegeneration (Alzheimer’s, Parkinson’s models).
Q: What is the effective dose range in animal studies?
A: Published studies report cognitive-enhancing and neuroprotective effects at 0.1–1 mg/kg (oral) in rodents—approximately 1,000 times more potent than piracetam.
Q: Are there human clinical trials for Noopept?
A: Limited human studies have been conducted in Russia, where Noopept is approved as a prescription nootropic.
