any differences in these acids in extraction ability or yield? or is the only important thing in an A/B getting the ph low enough?

was about to start an extraction using vinegar but then read in the handbook that vinegar didn't extract as well as phos. if that's the case I might as well use that, but a lot of people seem to prefer vinegar for some reason.

SWIM lost over half a gram of DMT when he dissolved it in PH 2 HCl for a tincture.
It completely denatured the spice which was tested to be very potent before the tincture was made.
SWIM is scared to use it for DMT now.

Vinegar has always served SWIM well. Whether for A of the A/B or making tinctures it has given excellent results.

No idea about phosphoric, never used it.
