NEP - functional use?

Anyone using this for functional purposes? It's convenient how fast, rapid and cheap it is. Perfect if you don't want to commit to a full use of an amphetamine/phenidate. Recent post a user mentioned he preferred it to them for his work, gave him nice stimulation without the robotic focus of the others.

I don't do the whole gigadegen vaping/stimfap thing, I know it's a factor for many but don't bother warning me about this. I have a 1g pack on my shelves for a couple months now and never had any problems, still haven't finished it. Problem is it's not as productive as amphetamines/phenidates actually, trades robotic feeling for scatterbrain-ness for me, and it gives me an anxious heart even in small doses, so the returns diminish extremely fast.

Anyone here using NEP (or similar non-serotonergic cathinones) for productivity purposes please report your regimen or any tips to improve effects.
