Fluorenol or 9-fluorenol, (AKA Hydrafinil) is a eugeroic nootropic very similar in action to modafinil.

Shown to increase wakefullness with a 39% increase in effectiveness of that of Modafinil.

Fluorenol is a weaker dopamine releasing agent, thus isn’t as likely to be euphoric and so less addictive than Modafinil.

Higher 5HT-6 affinity compared to Modafinil means less serotonin is removed from the synapse. Suggesting that Fluorenol is a better mood inhancer than Modafinil

Fluorenol belongs to a class of drugs known as Eugeroics. These are stimulants that produce long lasting mental arousal leading to wakefulness. The idea behind the production of these drugs is to enhance alertness without necessarily eliciting the peripheral body effects or better yet the abuse/tolerance/ addiction of the customary stimulants. And Fluorenol is no different.

Flourenol appears to have good chance of becoming a better alterntive to Modafinil and Armodafinil.
