There's really not a lot of solid info out there on Isopropylphenidate, so although I don't often post reviews, I feel compelled to contribute to the community. I hate reading trip reports because they're usually too long, and they're usually painstaking to read because most people who write them think they're Shakespeare or some shit, so this review is going to be my subjective opinion of the Isopropylphenidate.
I have a vast history of drug, RC, entheogen and supplement use, including a wide variety stimulants; however, I don't a lot of experience with cocaine and related substances, which I suppose puts me at a disadvantage in this review since Isopropylphenidate is said to affect dopamine. I do have some experience with Ritalin, though, and as you would expect, Isopropylphenidate is nowhere near as good as Ritalin. I have a moderate amount of experience with ethylphenidate, but this is from back when there were still good cathinone and PV-like substances available, so that comparison would be fruitless because it would be in relation to actual good stimulants.
I mainly got Isopropylphenidate as a study-aid for college courses and to enhance my performance in exercise and at work; however, I also used and abused it recreationally, which I feel is necessary if you want to get a good understanding of the true character of a drug. That said Isopropylphenidate is far better as a functional drug than a recreational drug. I feel very little urge to compulsively redose with Isopropylphenidate, but large amounts of the drug go well with alcohol. I started out with doses around 20 mg to be safe, but quickly worked my way up to doses of around 100-150 mg. Tolerance seems to build fast, but after years of drug use and abuse my tolerance tends to do that with just about everything.
My main complaint with Isopropylphenidate is the nausea I experience as I work my way up to higher doses. I've read that excess dopamine can do that, but Isopropylphenidate doesn't really seem to affect dopamine that much. If it did it would be far more euphoric and habit-forming, so there must be something else going on there. Adding alcohol diminished the nausea significantly, and taking a break to let tolerance get closer to baseline also helps.
I also tried Isopropylphenidate as a substitute to cycle off Modafinil for awhile, as I developed an insane tolerance. In comparison to Modafinil, I feel that Isopropylphenidate is complete crap. Using Isopropylphenidate as substitute for Modafinil is like using a hot dog as a substitute for a hammer. Furthermore, at this point in time when quality RCs are so difficult to get a hold of here in the states, I find it easier to get my hands on Modafinil, although it can take forever to receive from overseas.
In conclusion, if you are looking for a chemical to slightly enhance your productivity, Isopropylphenidate does an ok job. Is has very little habit-forming liability, and won't make you appear twisted to other people like amphetamines often do. Because it's a relatively weak drug, I wouldn't want to pay a lot of $ for my Isopropylphenidate; however, most RCs on the market in the states are overpriced right now, so I won't likely be ordering more Isopropylphenidate any time soon. I'd like to try 3,4-Dichloromethylphenidate, but I can't find it in the states and I'm reluctant to order from overseas cause I'm concerned my package will sit in customs forever, as my last few foreign RC packages did. One last aspect of Isopropylphenidate is that the effects only last about 4 hours, which is good if you like to sleep occasionally
