cocaine has a 17,000% markup from the original form
steroids are at about 500% on the wholesale side (of course depends on powers / quality etc...)
Imagine if you could buy a bottle of water for $1 and resell for $17,000, that's why the gov. keeps trying but fails with drugs like cocaine; thus, the next possible choice is steroids, smaller markup (less profits) but easier to shut down the little guys and EVEN the big guys.
This whole "investigation" really depends on how serious it's taken, if the gov (LE) has a lot of resources invested, then NO SOURCE IS SECURE - especially if you're out in the open. It would probably take 12 months, but a person even abroad could be discovered with time - just like any outside private investigation. I've seen sources go down in the past - even from China; it is true that they could have dealt 'other' products ont he side, but I have no proof of that.
I say, stick to your guns and stay safe; if you are a newcomer, just drop off for a while, and old-timer will make his/her own decisions. With all this heat and sources going down left and right, why risk anything? just get out. Personally, I see too many kids getting into the 'business' (so I hear it's called) and really not knowing what to do - you don't start a dental office with you working in it if you're not a dentist, do you? so don't get into these hot businesses if you dont know what you're doing.
I personally believe that running these 'hot' business ventures is just not worth it, for I can start a small->medium sized business and make about the same profits as I hear these kids make; however, it would be hands-off, legal and I wouldn't have a heart attack everytime I go to the mailbox. I see people brag that their business makes $10K per week, well, I hate to break it to you but legally I have ran 2 retail locations (food related) in the past that brought in net $12K per week (after tax), so don't let this stigma get you. USE YOUR HEAD!
