Behind the short name Noopept lies N-phenylacetyl-L-prolylglycine ethyl ester. The molecule is synthetic: a proline–glycine dipeptide forms its backbone, a phenylacetyl group sits on the amino end and an ethyl ester on the carboxyl end. At C17H22N2O4 and 318.37 g/mol it is far lighter than the peptide nootropics it usually gets compared with, Semax and Selank among them. Moscow's Zakusov Institute of Pharmacology designed it as a dipeptide-based counterpart to the racetam structure.
Research interest centres on three things: reports that it alters mRNA levels of BDNF and nerve growth factor in the hippocampus of rodents; anxiety-reducing and neuroprotective effects seen in animal studies; and how it compares with piracetam-family compounds. We sell Noopept as ready-made capsules in two research strengths, packed in a sealed bottle, HPLC-tested and accompanied by a Certificate of Analysis for each lot.

Questions about Noopept
What is Noopept, chemically?
N-phenylacetyl-L-prolylglycine ethyl ester — a synthetic compound whose skeleton is the dipeptide proline–glycine. It was created in Russia as a peptide-based relative of the racetams, and laboratories use it to study neurotrophin expression, memory tests and neuroprotection models.
Should Noopept be called a peptide?
Only partly. Its core is a proline–glycine dipeptide, but with a phenylacetyl cap and an ethyl ester attached it behaves like a small drug-like compound, not a typical peptide. It weighs just 318.37 g/mol — a fraction of peptide nootropics such as Semax or Selank.
How do you verify purity?
Each lot is HPLC-tested to ≥98% purity and its identity checked against the expected mass of 318.37 g/mol. You can view the lot's Certificate of Analysis on this page before buying; it sets out the complete analytical results.
Which strengths can I order?
Bottles of 60 capsules, either 10 mg or 30 mg each, sealed and with desiccant inside. Having two strengths with an identical number of capsules makes it easy to compare concentrations without weighing out loose powder.
