In a clinical study, stroke patients receiving omberacetam (Noopept) alongside physical rehabilitation showed greater improvement in cognitive function and asthenic symptoms than rehabilitation alone.
Omberacetam (Noopept)
Omberacetam (also known as Noopept or GVS-111) is a synthetic nootropic dipeptide (N-phenylacetyl-L-prolylglycine ethyl ester) developed in Russia in 1996 for its potent cognitive-enhancing and neuroprotective properties.

Available Evidence
Small clinical studies, mostly Russian, have reported cognitive improvements — e.g., in patients recovering from stroke when omberacetam was combined with physical rehabilitation. The evidence base is thin by Western standards: small samples, few independent replications, and no large multinational trials.
Rodent studies report improved learning and memory in amnesia models and neuroprotective effects, attributed in part to the active metabolite cycloprolylglycine (CPG) and glutamatergic (AMPA/NMDA) modulation.
Cell-based work characterizes omberacetam as a prodrug converted to cycloprolylglycine, with effects on glutamatergic signaling and neurotrophin-related pathways.
Claims that omberacetam is far more potent than piracetam, and of broad 'nootropic' benefits in healthy people, rest mainly on small Russian studies and animal data, with limited peer-reviewed replication.

Frequently Asked Questions
Is Noopept approved in the US?
No. Omberacetam is not FDA approved; it is sold as a research/nootropic compound.
How does omberacetam work?
It is a prodrug converted to cycloprolylglycine (CPG), which is proposed to modulate glutamatergic (AMPA/NMDA) signaling and neuroplasticity-related pathways.
Is there strong evidence for Noopept in healthy adults?
No — evidence is mostly from small Russian clinical studies and animal models; rigorous large trials in healthy adults are lacking.

Quick Facts
Mechanism
Rapidly absorbed orally and converted to active metabolite cycloprolylglycine (CPG) which modulates AMPA/NMDA glutamate receptors and enhances cholinergic neurotransmission
Safety Information
Start with 10mg once daily to assess individual response before increasing dose. Always pair with a choline source (Alpha-GPC or CDP-Choline) to prevent headaches. Avoid evening dosing as cognitive stimulation may interfere with sleep. Do not combine with other strong cholinergic or glutamatergic compounds without caution. Not recommended for pregnant or breastfeeding women due to lack of safety data. Individuals with liver conditions should consult healthcare provider before use.
