4-PMPD is certainly active and useful >250mg

I shelved it for a while after trying 60mg and barely feeling anything, but then I decided that it's probably just not very potent so I tried 150(obvious change but not useful), 250(feels like amphetamine with less euphoria and motivation), 330mg took today and it has much more energy, feels actually really good compared to my expectations and I now am getting motivational/focus effects. It also has a really gentle comedown for me, urge to redose is there, but not nearly as strong as amphetamine or such.

Enhances vision(and music a lot) and deeper thinking/more creative thoughts.

I know its not so much a nootropic, but it is very nice considering I got 10g when it first came out for like $2 haha.. plus I figured if anyone bought some it would be people here, so just a heads up.

Anyone have similar experiences?
