N-Propyl-MDA · 3,4-Methylenedioxy-N-propylamphetamine
SYNTHESIS: A total of 20 mL concentrated HCl was added beneath the surface of 20 mL propylamine, and when the addition was complete, the mixture was stripped of volatiles under vacuum. The slightly yellow residual oil weighed 20.7 g and set up to crystals on cooling. It was dissolved in 75 mL MeOH, and there was added 4.45 g of 3,4-methylenedioxyphenylacetone (see under
DOSAGE: greater than 200 mg.
QUALITATIVE COMMENTS: (with 200 mg) “There are the slightest hints of physical response, maybe a smidgin of a lightheadedness at the one hour point. Perhaps a slight teeth clench. Certainly there is no central mental effect.”
EXTENSIONS AND COMMENTARY: This particular drug, considering that it was without activity, has proven one of the richest veins of pharmacological raw material. Two clues suggested its potential value. A number of reports in the 150 to 200 milligram area suggested that something was taking place in the periphery even without any clear central effects. The term “body window” was used occasionally by experimenters, an outgrowth of the term “window” that was used (at that time, the mid-1970’s) to describe the mental effects of

EXTENSIONS AND COMMENTARY: There is need for more commentary. It must be noted that all of the above comments used rather modest dosages of
In general, the use of an MD compound (looking at it as a stimulant and primer) followed by a psychedelic, brings about an exaggeration and enhancement of the latter compound. Much work must be done in this area to make sense of it all.

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.”
The copyright for Book I of PiHKAL has been reserved in all forms and it may not be distributed. Book II of PiHKAL may be distributed for non-commercial reproduction provided that the introductory information, copyright notice, cautionary notice and ordering information remain attached.
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.
