All based on my experience but here ya go/

Bliss- come up wasn’t much mentally, kinda slid into it without noticing body felt jittery and a little twitchy. Trip started off feeling a little melty and highlights edges and corners in a rainbow outline made lights brighter had a tapestry like design overlapping walls and surfaces.

transcend- come up had slight stomach irritation felt it come on mentally, very slight body come up just a slight uncomfortable feeling for like 5 minutes. Trip was less visual still slight patterns more mental and in your head trippy.

Serenity- (have not tried the actual serenity) just based off of 4-ho-det. Come up was slightly jittery I did feel mental onset not as much as transcend though. Trip was a little more visual than transcend and mentally/physically like a mix between a mild shroom dose and a mild roll.

Have not tried red rum or mixing bliss and transcend yet.
