What are your thoughts on doing, let's say speed, 4-FA or 3-FPM, while still on things like LSD, DOC or 25I-NBOMe? Are they safe to combine at all? Do they synergize? I only know from experience, that 3-FPM kills the visuals from bk-2C-B for a while but otherwise the combo seems save, done it multiple times. Thanks for input!
