My girl and I tried Proscaline a couple of times together recently, last time I have mixed 45mg of 6-APDB, 28mg of 3C-P and 30mg of P, when she took just 25mg of Proscaline.
I am always interested in my girlfriend's opinion on psychoactives as she doesn't really know much about pharmacology or chemistry (not that I'm a professor at it :D), neither she has basic information on drugs, unless I'd tell her. Also she is terribly afraid of bad trips and a "mindfuck" in general but she is always curious about my research. So her opinion on this matter is very unbiased and genuine. She tried quite a lot of different psychedelics over the time of being with me, her favorites are LSD, AL-LAD and Mescaline, she likes MDMA and 6-APDB too.
After trying 25 mg of Proscaline, she said: "I feel like nothing can shake my calm, like I don't care anymore and it's good and fluffy! It reminds me of Mescaline in how it makes me feel. Yes, I feel pretty good, I like it!"
So we had great time playing mini-golf in a forestry settings, walking park trails and listening to music. Truly, the high from Proscaline (at doses less than 40mg) is very life-affirming, warm, with no "mindfuck" at all. Music sounded great, I truly was enjoying everything from classical to techno - music made me feel quite euphoric!
IME Proscaline synergised very well preloading with 700mg Aniracetam (usually enhances music appreciation for me), 500mg Phenibut and 600mg Agmatine. Also felt synergistic effects of P taken on the tail end of 6-APDB and 3C-P mix. Took forever before I went to sleep after all that taken (3C-P just lasts and lasts), stayed up for about 30hrs, then slept for 20hrs straight %)
IMO Proscaline is a great psychedelic "mixer" and very pleasant on its own - perfect "museum" level at 25-30mg and a definite mood boost. I think I'm going to need more of this material for thorougher research, it felt very pleasant!
