Piracetam

Supplement

A racetam nootropic claimed by many to have cognitive benefits however this has never been strongly supported in healthy individuals. Prescribed in the UK as a treatment for myoclonus. Potentially an ampakine. One of the first popular 'nootropics.'

Harm reduction

Supplements are not risk-free. St John's Wort, 5-HTP, MAO-B and MAO-A inhibitors interact seriously with recreational drugs.
Never take 5-HTP at the same time as MDMA or other serotonin releasers - the combination is implicated in serotonin syndrome. At most it is used in the days after, and even that is debated.
Melatonin and L-theanine are sedating; that is fine for sleep but adds to depressant load if you have been drinking.
Dose information here reflects general-use amounts from the sources, not an endorsement of using them in combination with other drugs.

Reagent tests show what a substance probably is, not how pure it is or what else is in the mix. Fentanyl and nitazene test strips are the only reliable check for those, and quantitative lab testing is better than both.

Tolerance, dependence and detection

Tolerancehalf tolerance after 3 - 7 days; back to baseline after 1 - 2 weeks

Addiction potentialnot addictive with a low potential for abuse
