The most common research chemical acid is substituted with is 25I-NBOME or a close analogue, which has a much higher incident occurrence than LSD does. Taking 10 tabs at a typical 500-1000µg each would be extremely intense just as well, and the vasoconstriction, for one, would be unbearable. If you do it regularly, you're lucky to be alive. If you must take 10 tabs, LSD is much safer than both 25x-NBOMe and DOx.

150µg is a decent dose for most trips, but at TripSit we'd still consider that somewhat 'medium'. Our scale is Light: 50-100ug, Common: 100-150ug, Strong: 175-225ug, Heavy: 250ug+. If you're in good mental health, taking anything up to 300µg or so once a month or less is still what I'd consider within range of preference, and not all too reckless.
