Realistically would a producer of drugs be able to cut out the middleman and sell on the markets? Could the markets handle the type of weight a producer would make? Lets say for example a large meth lab. Instead of supplying the cartel, could you ship packages through the DNMs, or is there not even close too enough people who use this too make that a viable option for producers?
People literally do this. You can literally order kilos of MDMA from labs in the Netherlands. TGUK sells bulk LSD from the UK, he seems to only be limited by blotter paper to put the shit on..... And theres several other crazy bulk suppliers of LSD in Europe, and you could even get in there and compete with them if you could match their prices and the quality was spot on.
You better be able to supply the cleanest, least cut product possible tohugh. Preferablly uncut, but, you know how that goes for things like heroin and cociane...
The biggest problem you're going to run into is supplying small orders. No one will buy bulk from a brand new vendor without trying them with smaller orders first, and selling small quantities is going to rake in a fuck ton of sales. It will quickly become difficult to handle the volume of shipping. Don't forget you have to be super careful about your OPSEC while shipping as well.
