Open Interactive CalculatorMetabolism & Excretion
Pathway
Rapidly metabolized by peptidases; primary active form is cycloprolylglycine
Elimination
Urine (as cycloprolylglycine and proline)
Important Nuances
Extremely short plasma half-life but neurological effects (BDNF/NGF upregulation) persist much longer (several hours). Effects are not directly tied to plasma concentration — active metabolites exert lasting neuroplastic changes.
Frequently Asked Questions
If Noopept's half-life is 15–30 minutes, why do effects last hours?
Noopept is rapidly converted to its active metabolite cycloprolylglycine, which triggers BDNF and NGF expression. These neuroplastic effects persist long after the parent compound has cleared — similar to how exercise has health effects that last beyond the workout itself. Effects typically last 3–5 hours per dose.
