Fladrafinil (CRL-40,941) Powder Vs Modafinil, Adrafinil powder

Many people often wonder – what is the difference between Fladrafinil powder, Adrafinil powder, and Modafinil powder? To understand the difference between these three smart drugs powder, you have to know them individually. Modafinil is a prescription drug for narcolepsy, which is a sleeping disorder that makes you fall asleep during the day. This drug consists of two different molecules namely Sinister (S-Modafinil) and Rectus (R-Modafinil), which is Latin for “left” and “right” respectively.

Both the S-Modafinil and R-Modafinil variants produce the same positive wakefulness effect. However, the body is quicker at processing the S variant, which means that it has a shorter half-life than the R variant. S-Modafinil has a half-life if about 4 hours only, while R-Modafinil has a longer half-life of 15 hours.

Since S-Modafinil and R-Modafinil have different half-lives, you will expect to get the strongest effects of Modafinil during the first five hours or so. Afterwards, most of the S-Modafinil will be filtered out of your body, but the R-Modafinil will still be left. Therefore, you will have about 50 percent of the initial dose in your bloodstream for another 7-10 hours.

Adrafinil powder, on the other hand, is a drug that gets converted to Modafinil in the body. It also consists of S-Adrafinil and R-Adrafinil. Since it has to be converted to Modafinil, it takes more time to “kick-in” compared to Modafinil. After it is converted, it has the same effects as Modafinil. So, the effects of Adrafinil are also strongest in the first five hours, and they slowly reduce in the next five hours.

Fladrafinil powder is similar to Modafinil and Adrafinil in terms of composition and effects. Actually, it is basically the same substance, except that Fladrafinil contains an additional molecule of fluoride. This addition significantly enhances the effects of Fladrafinil, making it easy for the body to absorb. In humans, Fladrafinil has an elimination half-life of 12-15 hours

Fladrafinil powder is said to be 3-4 times more powerful than Modafinil and Adrafinil. The minor alteration of one molecule induces an anti-aggressive response that Modafinil and Adrafinil aren’t capable of inducing. What’s more is that Fladrafinil is not only more effective than the two similar drugs, but it also has fewer side effects.
