Some of my best trips have been in the form of alphabet soups.
Usually it starts of with me just ingesting 1 substance, then after awhile i get bored and want to go further.
One i had last year was that i started with a nice dose of DIPT, but after the peak wore off i had just started hitting some nitrous and wanted to keep going going.
So i took a hefty dose of 4-aco-dmt and just a tad of 25-c (well under 500ug) and it was on!
Another time i had eaten some pretty weak lsd, but adding 300ug of 25i actually made it very interesting and euphoric.
Overall im not a fan of the nbomes, but when used in low doses as an additive they are quite good.
As long as one takes tolerance and total dosages into consideration it can be very interesting and novel to try these crazy combos.
The trips you get are totally unique and can be very giving.
But please use a mg scale and not a chinese porsline sppon please...
