15-20mg's Insufflated is quite lovely. Isn't "fiendish" or anything, and I could also eat on it. (Still on it, so not sure on the duration, first time trying it) Very little stimulant tolerance. I'm guessing 3-4 hours. Will update if anything changes drastically. First impressions (About +45 minutes) /very/ clean, and feels like I've taken a shot of Whisky, as I feel quite warm. So far I /doubt/ this will be a bingy drug. Or well, I would pick just Amphetamine if I needed to work say 30ish hours straight. Quite impressed so far, sadly I didn't just take Isophenmetrazine. Currently on
22mg's of Isophenmetrazine
30mg's Temazepam
15mg's Oxycodone
800mg's Gabapentin.
I do plan on trying this on it's own soon.
EDIT: Lasted 4 and a half hours, very very very easy comedown, that reminded me of Amfonelic acid. Which every time I did the latter I just hit baseline and fell asleep. Exact same thing here. Very relaxing drug (That sounds weird when I'm talking about a stimulant) yet just watching the leaves fall to the ground and being outside laying on a couch was perfectly fine, no bad side-effects. My BP/HR stayed normal the entire time. This isn't a drug to party on, I honestly would describe it being more of a nootropic than a pure stimulant. Lasted 4.5 hours total. Will 100% come back to this. The desire to work was there, but I was just content watching leaves fall off of trees and browsing Reddit.
Note: The reason the above /could/ have happened was because of the combo I was on. So do /not/ take this as a trip report, take this as just /my/ experience. Which well... there aren't many TR's I thought I should have added a tiny one to my post.
Overall: Very interesting drug, and I'm going to try it with just .5mg Clonazepam (Benzodiazpine addict) and see how that goes in a few weeks

If any questions, I will try to answer them (and if I can't, I'm 99.99999% sure someone else on here can)
