If you're just looking to have a shitload of dry compounds, I'd agree with everyone else about giving up on the primo. It's just too often faked (by the labs, the dealers, or the factories). Doesn't mean you don't have other options. Running Mast into the stratosphere - like, 1g+ - will get expensive in its own right, but might give you something similar. The "drying" effect will top out at around 500-600, yeah, but if you crank it high enough it'll also work fine as a recomp compound or even a bulking agent. Just watch for sides.
