I've tried MDPV today, it was the beige stuff. Snorted 30mg in total over 7 hours (I am a quite heavy guy). I felt fine, slightly euphoric, very focused and was prone to discussions about anything. Didn't experience anything related to sex drive though, even though after reading about that effect, I tried to watch some porn. No effect apart from the usual.
Now the effect is almost completely gone and I have a very very slight headache, but that could be because I haven't eaten all day. And I just tried some milk with strawberry nesquick. It tasted like a bite of old sofa. Well, like I imagine an old sofa would taste like.
