Yes there is and i would highly advise against doing it.
A suspension is a heterogeneous mixture unlike a solution which is homogeneous. Solutions have even distribution of the solute in the solvent whereas suspensions don't. Suspensions are good enough for some drugs and oral AAS bc if you over or underdose it won't make a significant difference in most cases. If you accidentally overdose on DNP bc it wasn't mixed enough or some settled and you drew from the higher concentration area, you could end up in the hospital and/or die. I use DNP, I have nothing against it at all but putting it in a suspension outside of a lab facility or without a heavy science background is dumb.
