Aniracetam provides calm focus vs stimulatory racetams (phenylpiracetam, oxiracetam)
Aniracetam is contrasted with phenylpiracetam hydrazide and oxiracetam, which are described as hyper-stimulatory (rapid heartbeat, 'sped up' feeling). Aniracetam produces the same cognitive enhancement outcome — laser-sharp focus — without stimulation. For anxiety patients who still need to function, aniracetam provides 'smarter but calm.' Oxiracetam is noted as needing to be mixed with DMSO for effectiveness.
