Noopept

Also known as Omberacetam, GVS-111, N-phenylacetyl-L-prolylglycine ethyl ester

Human trials

Not strictly a peptide: a small dipeptide derived molecule related to the racetams. Registered in Russia; human evidence is limited to small studies.

Not an approved medicine. Noopept is not an approved medicine for this use in Australia or the United States. This page summarises published research for information only. It is not a recommendation to use Noopept, and VialOwl does not sell or supply it.

Background

Noopept (omberacetam, GVS-111) was developed in Russia in the 1990s by designing a small dipeptide based molecule that mimics the structure of piracetam. It is registered as a medicine in Russia but not approved in Australia, the US or Europe.

How it is thought to work

Its exact mechanism is not well established. Russian lab studies propose antioxidant and anti inflammatory effects, protection against glutamate and calcium toxicity, and activation of the transcription factor HIF-1.

What is claimed, and the evidence

Side effects

EffectHow oftenNotes
Headache, irritability, sleep disturbanceFrequency unknownCommonly mentioned in user reports; no systematic human safety data in English literature.
Exposure to mislabelled or undeclared drugs in supplements
Serious
CommonA 2021 analysis of cognitive supplements found omberacetam at up to four times a typical dose, undeclared drugs, and 75 per cent of declared amounts inaccurate.

Warnings

  • Schedule 4 (prescription only) in Australia as omberacetam and not on the ARTG.
  • Supplements sold as cognitive enhancers have been found to contain unlisted drugs and wrong amounts of omberacetam.
  • Human evidence is limited to small studies from the developing country.
