What is Hydrafinil (Fluorenol)?

Hydrafinil (aka 9-Fluorenol) is a novel eugeroic nootropic that is very similar in action to Modafinil. It was originally developed as a research compound by a biopharmaceutical company named Cephalon Pharmaceuticals to promote wakefulness and alertness. Results from the animal study reported a 39% increase in effectiveness at improving wakefulness over a 4 hour period when compared to Modafinil.1 Due to its reported efficacy as a eugeroic agent, it is becoming popular among advanced nootropics users. Interestingly, users report less stimulating effects than Modafinil, but a greater ability to promote vigilance. Other reported benefits include attentional enhancement, increased motivation, subtle mood boost, improved cognitive function and ability to learn.

Compared to other popular eugeroic nootropics, Hydrafinil (Fluorenol) may have three main advantages: lower price, reduced stimulation and superior eugeroic efficacy.

Key benefits:

•    Increased alertness and wakefulness
•    Reduced fatigue and tiredness
•    Better concentration
•    Enhanced mental energy
•    Higher productivity

Recommended dosage:

The recommended daily dosage of Hydrafinil (Fluorenol) is 50 mg. As it is a powerful eugeroic nootropic you should not exceed the recommended daily dosage.

Mechanisms of action:

The precise mechanism of action is still unknown. However, a few possible mechanisms have been proposed. Firstly, it is believed that Hydrafinil (Fluorenol) may function as a weak dopamine reuptake inhibitor, which means that it increases the levels of dopamine neurotransmitter. As a result, a number of cognitive processes are improved. Secondly, it has been hypothesised that Hydrafinil (Fluorenol) acts as a serotonin 5-HT6 receptor antagonist. 5-HT6 receptors are located in the central nervous system (CNS) and it appears that their blockage can lead to improvements of cognitive performance in many different learning and memory paradigms.2 In addition, serotonin and its system plays a very important role in both cognitive and behavioural control. Therefore, some of the mild mood improvements reported following the use of Hydrafinil (Fluorenol) are attributed to this system.

Chemical structure:

Side effects:

Based on the current available evidence, Hydrafinil (Fluorenol) is reported to be safe. However, most of this evidence is anecdotal. Therefore, more human studies/trials with scientific evidence and analysis of its long-term effects need to be done.

Good premise but...
I am out on this one, I expected a kind of altered armodifinil but this is just not so useful. I may try it again on the odd occasion but for now it is just a novelty.

Verdict Still Out
First let me state that I have tried multiple vendors HYDRIFINAL & actually found it very inconsistent from vendor to vendor. (Inconsistent as in each time it's "different" in appearance, unlike say ADRAFINIL where the different vendors its "usually & should be" as you know a pinkish-salmon colored product & tends to be across the board various vendors. •••••••••••• NOTE: I've gotten HELLA BUNK "HYDRIFINAL" from other tried vendors. From basically being "Chucks of FOAM!" With zero taste nor any effect whatsoever & I CAN HONESTLY SAY THIS "HYDRIFINAL" is unlike Any others as far as "BASE FORM" & thus makes it yet another "variation" as far as appearance compared to "BUNKNESS IVE RECIEVED" , & THUS far (3-days in) I can HONESTLY SAY THIS IS THEE BEST IVE USED & plausible benefits as a nootropic. ••••••••••••••• So, being each time NOT ONE HYDRIFINAL from ANY vendor has been a basic duplicate or in general "consistent raw" & ALL have been TORALLY DIFFERENT. (So I kinda don't know what "REAL HYDRIFINAL" I guess should look like. ••••••••••••••••• THUS FAR: 1st it's also totally different from "other HYDRIFINAL" I've ever gotten. 2nd: I BELIEVE THIS HYDRIFINAL ACTUALLY "WORX" compared to others BEST HANDS DOWN!! As I know it's at least "NOT BUNK" unlike each other HYDRIFINAL I've tried & ALL just chalked up to A LOSS!! This product is "different" so I can only assume without a steady across the board variations make it hard to "compare" however... I will say ITS THEE BEST HYDRIFINAL IVE EVER BOUGHT!! & possibly order more after more testing. (FYI: IF U GET FOAM LOOKING STUFF ITS BUNK AS HELL!!) These are tablets & again the first time I've gotten HYDRIFINAL in a tablet form... However the others HV ALL BEEN BUNK!! These I can't say are the Bomb just yet... But comparative "I DONT FEEL LIKE ITS JUST MORE BUNKNESS" I thus far am the realm of "benefits" after 3days but the "verdict is still out".... IF I ORDER MORE ILL LEAVE ANOTHER REVIEW "VOUCHING" for it or not. I DONT FEEL RIPPED OFF AT LEAST!! •••••••••••••••• & I know the jury is still out about HYDRIFINAL as "more testing" need be done as a whole, but as of now... I WOULD/WILL PROLLY ORDER AGAIN IF RESULTS KEEP UP & BENEFITS SEEN. ---4 out of 5---
