It is vastly different from country to country. Check your country's laws first! check sites like http://www.longecity.org/forum/ or reddit's /r/nootropics for reliable suppliers.
I take noopept 20mg daily sublingually or orally, and occasionally modafinil.
Modafinil works really well for me (300/400mg keeping me awake and FOCUSED but not buzzing/twitchy) but worked poorly for my brother (no noticeable effect at similar dosage).
Since taking noopept I have noticed more of a willingness and now desire to learn, something which was an issue in my past. It also seems to help me work for prolonged periods of time without getting burnt out. (anecdotal, could well be placebo effect but it works for me!) Feel free to ask me anything.
https://news.layervault.com/ Designer News is quite good for design discussion. It's an invite only site though ( I don't have an account so I can't invite - sorry! )
