Fluorenol or 9-fluorenol, (AKA Hydrafinil) is a eugeroic nootropic very similar in action to modafinil.
Creators of the drug, Cephalon, propose that it’s more potent in its stimulating effects and can be considered as the successor of modafinil.
The creators found a 39% higher effectiveness in prolonging wakefulness in mice over four hours. It can be considered less addictive than modafinil being a weaker dopamine reuptake inhibitor, responsible for the rewarding effects of the drug. As of 2014, this has not been clinically studied nor confirmed.
Fluorenol vs Modafinil
Some of the differences between Modafinil and Fluorenol:
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
As mentioned earlier, this drug hasn’t been involved in any human clinicial testing or trials therefore a safe dosage and any potential side effects have not been established.
Ceretropic hypothesise that hydrafinil has a higher potency than modafinil and suggest to take just a fraction of the dose you might take of modafinil.
In relation to side effects, one person said he suffered a period of sleep paralysis following hydrafinil usage.
The majority of users online agree that hydrafinil appears to have weaker effects than its analogue and that the crash is considerably milder.
Again, these are just anecdotal claims and have not been supported by any scientific evidence.
