Phenylpiracetam (Phenotropil) is a nootropic of the racetam family, and as its name suggests it is a phenyl- derivative of piracetam. Phenylpiracetam is reported to be more neuroprotective than piracetam is, but also possesses psychostimulatory properties and is reported to enhance physical performance.

There is a fair bit of research to suggest that phenylpiracetam is effective, like other racetam drugs, in attenuating the rate of and symptoms of cognitive decline. Many of these studies use phenylpiracetam for over one month's time, and the benefits seen may only apply to organic causes of cognitive decline (dementia and stroke) rather than traumatic brain injury.

There is only one rat study noting cognitive enhancement in otherwise healthy young rats, and this study only noted benefit with the R-isomer (the racemic mixture, which is commonly sold, failed to outperform control). While cognitive enhancing properties of phenylpiracetam in youth cannot be ruled out, they are possibly distinct from the psychostimulatory properties (which occur with said racemic mixture and the R-isomer).

Cognitive Function and Brain Health



Do not confuse with piracetam (Parent molecule).

It is banned by the World Anti-Doping Agency (Olympics) due to its reported psychostimulatory and cold resistance properties

How to Take It

Phenylpiracetam is taken at a dosage of 100-200mg acutely, and this dose is taken 2-3 times per day (totaling a daily range of 200-600mg).

The lower range seems effective, but the optimal dosage is not yet known.

The R-isomer appears to be more active on the common usages of phenylpiracetam (stimulation and cognition) than does the S-isomer, and while the racemic mixture (commonly sold version) is effective for cognitive decline it is not certain if it works for nootropic purposes in youth.
