@Dan_Dascalescu thanks for signing up
Do you expect the survey questions to be sufficient, vs., say, a Quantified Mind cognitive test? The site is well-suited for this type of experimentation.
I'm in contact with Quantified Mind and considering using them in addition to surveys.
Modafinil, as long as you manage to guarantee users will stay legally safe.
Modafinil is probably not going to make sense for our model because it requires a prescription in the US, so users would have to supply their own. How would you organize this experiment if it were up to you?
It depends on the supplement, but I think at least month, and at most six months (see the Gotu Kola supplementation, which allegedly kicks in only after 6 months).
Cool, thanks for the feedback. I agree that it'll depend on the drug and how long it takes to take effect. Bacopa is another one that doesn't seem to work until a few months in.

Cool. Thanks, interesting!
