MDMA: Because it makes music sound beyond amazing, it makes a very introverted and shy guerillabedlam become more social and willing to open up to people. I learned how to dance due to it's effects on inhibition and it takes a little bit of everything from the psychoactive world (some stimulation, some psychedelia, some relaxation) Great compound! MDA: Pretty much the same as MDMA except it's a bit more exhausting of an experience, not quite as empathogenic but many quality features to the experience. Methylone: A bit more controllable than the MDxx's and mephedrone at usual oral doses, fairly hallucinogenic when injected. Mephedrone: Crazy, wacky entactogen. Adderall: Prefer the high from Meth but I have limited experience with Meth and Adderall doesn't produce nearly as bad as a crash.
By far, my favorite is Dextro-amphetamine. It has all of the euphoria and mental stimulation of "Adderall" (which is a mix of dextro AND levo amphetamine, levo being exclusively physically stimulating) but without any of the nasty jitters, heart rate increases, or feelings of being strung out that accompany high doses of Adderall. Until I had D-Amphetamine, my favorite stimulant, actually, was Methylphenidate (Ritalin). If crushed and insufflated, it provides a wonderful euphoric high. It also has less jitteriness than Adderall. But D-Amphetamine is 10 times as euphoric and even less physically bothersome. The pharmaceutical brands for D-Amphetamine are Dexedrine and Vyvanse. Vyvanse technically only turns into D-Amphetamine in the stomach but for all intents and purposes, it is straight D-Amphetamine.
MDMA, by far. I can't recall how many raves and bike rides I did with my friend Molly. The rush of euphoria I felt while going downhill at full speed and making jumps during the peak is out of this world.
Probably gotta say MDMA but only if I have a nice downer afterwards. I enjoy the clarity it gives me and the ability to have thoughts similar to those on LSD without the confusion and chance of everything spiralling out of control. To me MDMA is like LSD but you're gaurenteed to have a good trip and tons of energy. Only thing I don't like is the yucky feeling I get afterward, but usually that can be cured with a nice dose of Oxy or a similar opiate or downer.
I'll always have a place in my heart for 4-MMC. Although I prefer M1 to it, Mephedrone was more of a stimulant with empathogen effects.
