ah yes, the Family...what is it? its a state of mind - nah, a way of life. no borders, no corners. you know by the eyes. this, of course, helps maintain a constant benchmark as far as quality goes.
so what makes family acid? for one thing, its free. hence its not commercially available. the intent is not to line pockets but to bring more anti-entropic light and to heal. this assures the material - family acid - is always of visionary / psychotherapeutic grade; white fluff / needlepoint or one-off / mythical guru batches - which as far as the world believes don't exist...of course.
for these reasons the actual dosage may per unit stray wide from commercially viable range, 500ug tabs are not unheard of and there is one crew that makes their liqqy at 2,000 ug/drop - for internal use of course.
but a couple dooods with a bottle of amber / t.j. mother liqqy and half a book of off-the-net paper does not a family make...
