Powders into solid (opiates)

[dopeyfour]

So i live between 2 major opiate/fent open air markets. One market the stuff is heavily cut with variety of substances such as Xylazine, benzos, dormin sleep pills, form of quinine. It comes in powder form. Obviously there's tons of cut but they potentiate each other. The other market, ppl only buy chunks. $20 chunk with a dormin pill or half gram or full gram...having tried both I believe they are similar I'm potency. My guess is they are buying fent adding cuts or heroin ot nitazenes or whatever n then somehow getting it back into a rock form. I've heard of a couple methods of doing this (adding cut) & somehow turning back into rock form. Does someone have experience with this & know a simple way? Obv sellers it's best to keep as uncut as possible but some areas adding certain things is a must to stay competitive......(someone once suggested mixing well then using strong hydraulic press or jamming into a door.) I'm not mechanically proficient btw)
