About a week and a half ago I wrote a rave review of smoking 15 mg of 4-AcO-DALT, but I deleted it a few days later because it was too informal and I didn't want my first impression to paint the wrong picture of this substance. This time, I decided to write a more professional trip report and give my thoughts.
Setting: House Party Regular Meds: Currently none Drugs taken in past 24hours: I had done some ethylphenidate, etizolam and mebroqualone the night before and had drunk around 1/4 of a bottle of rum before taking the 4-AcO-DALT Previous psychedelics experience: Phens: 2C-B, 2C-B-FLY, 2C-C, 2C-D, 2C-E, 2C-I, 2C-P, 2C-T-7...
At the time of the Experience, I'm taking almost daily; 200mg magnesium citrate, 1000mg Cod liver oil, B-complex (100% RDA rec)+ 0.25 mg Melatonin at night to Help with sleep. 16.15- took 60 mg 1 hr after a light meal, also took one sickness pill with the meal in case of nausea.
Experience - more substances than I care to mention but not many tryptamines, only 5-MeO-DALT and whatever's in mushrooms before this. I am not on any meds. Set and setting - I'm home, I'm happy, I've had a couple of beers. Let's give this a try...
Used mixture: 35mg of 4-AcO-DALT and a hint of citric acid, dissolved in saline solution. Set & Setting: Alone in a studio with some low lights and soft trance music. Interested in the substance, emotionally a bit shaken, but well, physically healthy.
