Just be aware that you are increasing your metabolic rate, and there is little to say what the very long term effects are. Piracetam is effective in a number of ways, and it would be very dangerous to assume that this is the one drug which has profound effects without the possiblity of profound adverse reactions.
That said, other than major overdose, the issue seems to be primarily an issue for those with a pre-exisitng psychiatric disorder (especially anxiety), but then, it's also effects clotting in a fairily unusual (albeit helpful) way.
To be blunt, I wouldn't take this drug as a nootropic, it has too many other effects. Yes, it seems to clear your brain nicely, and even reverse some damage in mice, but we're not mice, and it may be that you're cashing in life-span or your endocrine system for a boost now. That is pure supposition, but keep in mind how "miraculous" amphetamines have been... with a few NOTABLE downside.
If you don't NEED a drug, don't take it. Yes, it doesn't act as a stumulent or depressent in the neurological sense, because it does its work at the enzymatic and
mitochondrial level. Here is a quote from Wikipedia (which does a good job for the Method of Action)
wikipedia said:
Piracetam improves the function of the neurotransmitter acetylcholine via muscarinic cholinergic (ACh) receptors which are implicated in memory processes.[14] Furthermore, Piracetam may have an effect on NMDA glutamate receptors, which are involved with learning and memory processes. Piracetam is thought to increase cell membrane permeability.[14][15] Piracetam may exert its global effect on brain neurotransmission via modulation of ion channels (i.e., Na+, K+).[12] It has been found to increase oxygen consumption in the brain, apparently in connection to ATP metabolism, and increases the activity of adenylate kinase in rat brain.[16][17] Piracetam appears to increase the synthesis of cytochrome b5,[18] which is a part of the electron transport mechanism in
mitochondria. It also increases the permeability of the
mitochondria of some intermediaries of the Krebs cycle.[16]
That's doing a LOT, and it's also increasing your most basic measure of metabolic rate. I would save this for when one NEEDS it, not for fun and pofit, so to speak. Then again, we still pump our soldiers full of "go/no-go" drugs (from Dextroamphetamine, to newer versions such as Modafinil), and it usually takes time for the full ramifacations of that to become clear. These are people who's alert state is life-or-death... is yours?
