making suspensions in WATER is difficult, and water suspension are much more prone to bacteria, etc.
iow, if you are not a true lab, i wouldn't think it was worth it, and would be risky and difficult
as for suspensions in oil - i haven't used them for 3-a, but i have used them for other base compounds (4-ad). they work fine
BA, BB, Oil as carrier, and about 10% peg - that's the ticket.
it will seperate into layers. shake it up before use.
not unpleasant at all with 4-ad. as for 3-a? who knows?
