I think when I did my first nexus flip I took around 220mg of MDMA in two doses and maybe 15mg of 2C-B 2.5-3 hours after my redose and that was pretty much perfect for me. It created an extremely euphoric but very different entity than both substances on their own. The body feeling, the closed eye visuals and the physical euphoria were insane, I really need to revisit this combination some time, it's been a while. Even thinking about it makes my mouth water lol. I combined 5-MAPB with a little bit of 4-HO-MET a few weeks ago and while it was a really good combination it doesn't hold a candle to MDMA + 2C-B. They just stacked on top of each other without interacting too much while MDMA and 2C-B create a completely different, extremely euphoric, synergistic high when timed properly.
Yup AL-LAD + 2C-B was the best psychedelic combination up to date, completely obliterated my field of vision. Tripped absolute sack that day. Good times
