Noopept is the brand name for N-phenylacetyl-L-prolylglycine ethyl ester, a Nootropic molecule similar to Piracetam. Noopept may alleviate cognitive decline.

Noopept is most often used for


Noopept is the brand name for N-phenylacetyl-L-prolylglycine ethyl ester , a synthetic nootropic molecule.

Noopept has a similar effect to piracetam, in that it provides a mild cognitive boost after supplementation. Noopept also provides a subtle psychostimulatory effect.

Noopept has a much lower standard dose than piracetam (10-30mg, compared to 4800mg), and it provides a general neuroprotective effect after supplementation. This neuroprotective effect occurs during various states of cognitive trauma, including oxidative stress and physical trauma. There is, however, no evidence to suggest Noopept provides benefits for people with no cognitive ailments.

More studies are needed to determine the main mechanisms responsible for Noopept’s neuroprotective effect.

The only human study comparing Noopept and piracetam suggests the two have a comparable effect, once the smaller effective dose is taken into account.

What else is Noopept known as?
Note that Noopept is also known as:
  • N-phenylacetyl-L-prolylglycine ethyl ester
  • Noopeptide
  • Ноопепт
  • GVS-111
Noopept should not be confused with:
  • Piracetam (Basic racetam
  • but different molecule)
Dosage information

To supplement Noopept, take 10 – 30 mg, once a day, for up to 56 days at a time. More research is needed to determine the optimal human dose for Noopept.
