N-Isopropyl-MDA · 3,4-Methylenedioxy-N-isopropylamphetamine
SYNTHESIS: To a well stirred and cooled solution of 14.75 g isopropylamine in 100 mL MeOH there was added 4.45 g of 3,4-methylenedioxyphenylacetone (see under
DOSAGE: greater than 250 mg.
QUALITATIVE COMMENTS: (with 250 mg) “At 35 minutes there was an extremely slight head disturbance which increased over the next few minutes. I would have missed it if there had been any sensory input at all. At the one hour point there was a slight physical malaise, but no ‘open window’ of any kind, either like baseline.”
EXTENSIONS AND COMMENTARY: The structure of MDIP can be looked at as exactly that of
Here is an example of a primer experiment that involved MDIP. Some five hours following an inactive trial with 120 milligrams of MDIP (maybe a slight disturbance at one hour, nothing at two hours) a calibration dose of 80 milligrams of plus one was achieved at one hour. At this point a second 80 milligrams was added to the inventory that was already on board, and the general intoxication and the eye effects that followed were completely explained by the MDMA alone. It was obvious that the two drugs did not see one-another.
Sometimes an experiment can involve the assay of an unknown material at the supplement time of an active drug. This has been called “piggybacking.” Here is an example. At the five hour point of an experiment with 140 milligrams of plus one which had not laster more than two hours) a dosage of 200 milligrams of MDIP rekindled a +1 experience, a pleasant intoxication of the MDE sort, but one that was quite invested with tremor and some feelings of eye-popping. It was almost as if the physical toxic effects outweighed the mental virtues. Imagine an iceberg, with the bulk of its mass underwater. The MDE had had its own modest effects, and had submerged into invisibility, and the response to a little bit of an otherwise inactive MDIP was to refloat a bit of the otherwise unseeable MDE.

About PiHKAL · info
This version of Book II of PiHKAL is based on the Erowid online version, originally transcribed by Simson Garfinkle and converted into HTML by Lamont Granquist. I drew also on “Tyrone Slothrop’s” (Unfinished) Review of PIHKAL to enumerate the many analogues mentioned in PiHKAL but not described at length. Many, many others have since been added.
I have tried here to expunge any artifacts introduced by the earlier transcriptions and restore the typographic niceties found in the printed edition. I’ve also made minor changes to some chemical names in line with current nomenclature practice. Typically the change is little more than expanding a prefix or setting it in italics. The history page has further details.
“At the present time, restrictive laws are in force in the United States and it is very difficult for researchers to abide by the regulations which govern efforts to obtain legal approval to do work with these compounds in human beings.“No one who is lacking legal authorization should attempt the synthesis of any of the compounds described in these files, with the intent to give them to man. To do so is to risk legal action which might lead to the tragic ruination of a life. It should also be noted that any person anywhere who experiments on himself, or on another human being, with any of the drugs described herein, without being familiar with that drug’s action and aware of the physical and/or mental disturbance or harm it might cause, is acting irresponsibly and immorally, whether or not he is doing so within the bounds of the law.”

PiHKAL is the extraordinary record of the authors’ years exploring the chemistry and transformational power of phenethylamines. This book belongs in the library of anyone seeking a rational, enlightened and candid perspective on psychedelic drugs.
Though Sasha and Ann have put Book II of PiHKAL in the public domain, available to anyone, I strongly encourage you to buy a copy. We owe them — and there’s still nothing quite like holding a real book in your hands.
