Someone I know had an a-pvp sample a while back and and ethylphenidate one as well. Without having had any other moreish research chems, he does find the less is more thing to be sooo sooo true. He has honestly found that IV'ing works best for him as when he's on the road a lot and the whole preparation ritual takes some time... time which he could have fiendishly done a copious amount of lines. Also, he does get a rush which is somewhat absent from other roa's (he quit inhaling anything into his lungs after years of marijuana and then the another 7 of spice). So, he's no stranger to addiction, which this one has a strong potential for. It can keep you awake an ungodly long time after even minimal dosing reports another friend who did not accept the xanax offered as he doubted the small line he did would affect him so. He was texting at 4:45am- friend one smartly had his ringer turned off so as not to set off the family. So, friend one needs to sleep at night to not seem manic and on drugs so as to not lose his family. Which brings him back to IV'ing which seems to not last as long, thus having less hours to consume for consuming sake. With 100 mg seroquel, friend one can sleep 4-6 hours before waking and then redosing (of course). Hmm, this could end tragic. Be careful. It's not a brain stimulant like ADHD meds, it's a moreish'ish body thing that can cloud your thinking (at least it has mine). Oh, and after IV'ing 100mg +- (not suggested), he did hallucinate some. However, he did get sleepy for some reason (maybe that was the 3mg xanax kicking in too), speech was kinda screwed up (even tone) and he was afraid of being "caught" for being f'up. Heartrate never seems to get into or even near dangerous territory. He had a plunger filled w like 70mg this morning, found a vein in his hand, got about a third of the way through and felt a little stinging like he had lost it. So, he stopped and pulled out and has been high as hell. More adictive than euphoric. He needs to get some work done.
