How much does it cost?
I ordered from here at a price of $46 for 500g each of piracetam and choline citrate, plus $10 for gel caps and $20 for a scale (which is independently useful).
How soon do you start becoming desensitized to it, if at all?
I could not find any reported instances of desensitization to piracetam, so I don't think it's an issue.
I'm trying out nootropics, adding them one at a time. Next on my list to try is sulbutiamine; I've seen claims that it prevents mental fatigue, and it too has basically zero side-effect risks. Also on my list to try are lion's mane, aniracetam, l-tyrosine and fish oil. All of these are unregulated in the US.
I also use adrafinil, which greatly improves my focus. However, it's more expensive and it can't be used continuously without extra health risks, so I only use it occasionally rather than as part of my daily regimen. (There's an expensive and prescription-only related drug, modafinil, which can be used continuously.)
Sounds good. Be sure to report back once you test out the others-- nootropics are very interesting to me, and I think generally useful to the community as well.
