^Love isn't a chemical, its a chemical response.
Oxytocin would be a better chemical for the closest effects to love. Of course it also has to do with serotonin, but the loving everything comes from oxytocin.
Methylone, it lacks some of the empathy but everything feels really nice, maybe it doesn't act on oxytocin... The tactile response is still very much there, but its not as lovey... Its a hedonistic one, but its on a similar level.
Feels a little lighter than MDMA, like a few cups of coffee worth of energy and lots of warm and happy.
2c-b has some rollish qualities for most people, but its a little visual. Most of the people who have tried 2c-b loved it. Doses 20mg and under are generally accepted as one that most could go to a museum and look at art without turning any heads. It feels ok to be around people, social interaction is easy, its bright and colorful. Its a favorite.
