Nootropics 9-Fluorenol

Hydrafinil, also known as 9 Fluorenol is an unregulated synthetic drug by Cephalon Pharmaceuticals used as an eugeroic (attentiveness advancing agent). After its synthesis, fluorenol was one of the few agents to be considered as a theoretical successor to the advanced and FDA-approved drug. Studies on animals demonstrated that fluorenol displayed approximately 39% more noteworthy eugeroic viability than modafiniI over a short-term span.
Cephalon scrapped advancement of fluorenol as a potential eugeroic. Instead they guided their research and development in the creation of armodafiniI. ArmodafiniI, which is sold under the brand name "Nuvigil" would get to be known as the official pharmaceutical successor to ProvigiI, leaving numerous to ponder why not fluorenol?
Discussions hypothesize that fluorenol's was previously used as a bug spray in the late 1930s, and that it demonstrated lethality to aquatic life, and a lapsing Cephalon patent may have been the cause to suspend its development. Starting 2015, fluorenol has recaptured prevalence among nootropic fans and is presently being sold as an unregulated compound online under the brand name "Hydrafinil."

Dopamine reuptake inhibitor:

 An increase in dopamine production is known to improve cognition. 

Hydrafinil plays a role as a dopamine reuptake inhibitor, increasing dopamine concentrations.
5-HT6 antagonist: Antagonism of 5-HT6 receptor can result to increase in norepinephrine and dopamine concentrations in the prefrontal cortex, as well as increasing the production of choline and glutamate in different parts of the brain. Makers of Hydrafinil theorize that it functions as a 5-HT6 receptor antagonist.

Increase Glutamate levels: 

As mentioned earlier, antagonism of 5-HT6 receptors increases the production of glutamate in the brain. This could lead to enhanced memory and learning process. There is a great possibility that Hydrafinil's function as a 5-HT6 receptor antagonist could result in the improvement of cognitive performance.

Increase Norepinephrine levels: 

Manufacturers of Hydrafinil(9 Fluorenol) claim that it increases norepinephrine levels specifically in the prefrontal cortex by antagonizing 5-HT6 receptor. Increase in concentrations of norepinephrine could result to improvement of cognition. However, there's no enough evidence to prove this theory.

Increase Histamine levels: 

Hydrafinil(9 Fluorenol) is known to enhance histamine levels in the hypothalamus. Histamine plays an important role in normalizing our circadian rhythm and regulating sleep-wake cycles.

Dosage and Cautions:

In any case, it is always good to start at the smallest dose then gradually increase it once you have become familiar with its effects. The usual dose of Hydrafinil is 50 mg, taken 1 to 3 times a day as needed.
