Please feel free to correct me in regards to the following but based on what I've read over at examine.com and elsewhere, the half lives for the various racetams are as follows
Aniracetam 2 hrs
Phena, Prama and Pira 4-5hours
Oxiractem the longest at 8+ hours
Others?
Based on personal experience only with Aniracetam, even though it has a short 2 hour half life, I still notice residual effects in the evening if I take a single modest dose first thing in the morning.
So what are some estimates on how long before the various racetams are completely eliminated from the body?
