Modafinil vs Hydrafinil: Difference Between…

Unlike modafinil, Hydrafinil is NOT approved by the Food and Drug Administration (FDA), nor is it administered to treat any of the sleep disorders for which modafinil is prescribed [5]. Without FDA authorization, its strength & safety profile isn’t strictly regulated, so it is most reasonable to approach its use with extreme caution. Also, it doesn’t stay long in the body, thereby benefiting a satisfactory night’s sleep.

Let’s explore more between their dosage, negative effects, & interaction.


As noted earlier, Hydrafinil is deemed 39% more influential than modafinil. In simple math, this implies that Hydrafinil 50 to 100 mg dose equals 100 to 200 mg of modafinil.

Because there are yet more scientific investigations required to confine the exact Hydrafinil dosage, it’s great to employ the compound, obtainable in the form of powder or capsules, in the dose of 50 to 150 mg. A max. of 150 mg of Hydrafinil powder can be administered in hourly intervals. Additionally, vigilance should be exerted to not consume too much of it due to its high strength.

The physician’s counsel is very important to adhere to when taking such a product to obtain more precise dosage recommendations.

Ingesting the highest dosage of Hydrafinil for many days in a row isn’t prudent. Sticking to a 50 mg dose is certainly safe, since it’s unlikely to induce any negative effects. Besides, if taking 50 mg isn’t giving you the anticipated effects, consult a physician before opting to raise the dosage.

Modafinil dosage is well studied, and it’s advisable to use 200 mg. However, based on the outcome, it can be increased to max. 400 mg or lower to 100 mg or so.

However, most individuals who have used Hydrafinil report no extreme health risks. It’s typically contemplated to induce more infrequent adverse reactions than modafinil. Since Hydrafinil hasn’t gone through any human clinical trials at the time of writing this guide, there is no way of fathoming the safety of its long-term use.

Both nootropics can be taken with or without food. However, taking then a fat meal may result in a little longer time to start working. Also, circumvent mixing any of the nootropics with alcohol.
