Noopept
Also known as: N-phenylacetyl-L-prolylglycine ethyl ester, GVS-111, Omberacetam
Noopept is a potent dipeptide-derived nootropic from Russia, structurally related to piracetam but estimated to be 1,000 times more potent by mass. It enhances memory consolidation, learning, and recall while providing neuroprotection via BDNF and NGF upregulation.
Half-Life
~5–10 minutes but metabolite (CPG) effects last hours

Key Benefits
- Enhances memory formation and recall
- Improves learning speed and cognitive processing
- Neuroprotective via BDNF/NGF upregulation
- Anxiolytic at low-to-moderate doses
- Improves verbal fluency and information processing
- Antioxidant (reduces oxidative damage in neurons)
- May improve cognitive symptoms of mild cognitive impairment
Mechanism of Action
Noopept is metabolized to cycloprolylglycine (CPG) in the body, which activates AMPA/NMDA glutamate receptors and enhances long-term potentiation (LTP) — the cellular basis of memory formation. It also upregulates BDNF (brain-derived neurotrophic factor) and NGF (nerve growth factor), promoting neuronal survival and synaptic plasticity. Noopept also modulates alpha brain wave activity, facilitates inter-hemispheric transfer, and has anxiolytic effects at moderate doses via stimulation of inhibitory GABA-A receptors.
Dosing Protocols
Standard Cognitive Protocol
- Dose
- 10–30 mg
- Frequency
- 1–2x daily
- Timing
- Morning and/or midday; avoid evening (stimulating)
- Cycle
- 56 days (standard Russian protocol), then 4 week break
Sublingual fastest onset; may stack with a choline source (Alpha-GPC/CDP-Choline) to prevent headaches
Microdose Nootropic Protocol
- Dose
- 5–10 mg
- Frequency
- 3–5x per week
- Timing
- Morning
- Cycle
- Indefinite with 1-week monthly breaks
Lower doses often reported as more anxiolytic; higher doses more stimulating

Contraindications
Avoid with hypersensitivity to racetams. Use with caution in bipolar disorder (stimulatory effects). Not for pregnant/breastfeeding. Avoid high doses in epilepsy.
Storage
Store powder at room temperature in airtight container away from moisture and light. Very stable compound. Solutions should be stored at 4°C.
