Are there reputable sources online to obtain Modafinil safely? It seems to be a very popular nootropic but on the other hand is only available in the US via prescription.
From Wikipedia:
"Adrafinil is a prodrug; it is primarily metabolized in vivo to modafinil, resulting in very similar pharmacological effects. Unlike modafinil, however, it takes time for the metabolite to accumulate to active levels in the bloodstream."
You should monitor your kidney enzymes if using it long-term; I've never had any issues.
Plenty of places selling it for $20/30 300mg caps via Google Shopping search.
I don't think there are (m)any cases of people being busted for importing/simple possession, but if you were to get arrested for something else and had it on you, I wouldn't be surprised if you get additional charges.
Point being, this isn't a legal supplement you're ordering through the US Postal Service.
