If you were going to start a band, more than likely you would enlist the help of other people.... Like lets say you can sing, but don't know shit about the drums or guitar--- Your band is going to suck if you try to do everything yourself.
If you were going to make a movie, you would need the help of a producer, a director...and, it helps if you have actors as well.
One of the biggest reasons sources go under is because some idiot decided to learn the art and science of brewing some shitty gear, then decided (out of greed) that he would also be the guy who did the packaging, the shipping, the fund collection, the website construction / maintenance, materials ordering/reception, as well as the customer service. The undertaking of this business is immense, and requires a complicated system of logistics that involve proper timing and movement of people, material, and product. It is a cohesive system with MANY people working together and those people must be cut from the right cloth--- the ability to work together, maintain honesty, and stand strong in the face of adversity when (not if) things don't go as planned.
When people set out to do this, they often think it's going to be easy... not realizing that in order to be safe (not entirely safe--no such thing.... but safe as possible) they are going to need 8-10 people (some of them in other countries) assisting in some way. So... if your source is having trouble getting packs out frequently, (on a regular basis---ALL sources have occasional lags due to circumstances beyond their control), sends packs that look like shit or not secure, doesn't communicate well with you, or made you cry by yelling at you because he can't deal with the pressure, then those are red flags that should be considered.
And just as a friendly note to my fellow sources---- if you're dealing meth or weed out of your house along with your little steroid racket, it's only a matter of time before your only source of added protein is going to come by taking someones food tray in jail on chicken day..... or.... doing a favor in the shower. Have some consideration for the innocent people here on eroids that had nothing to do with your love of heroin. They trusted you with their hard-illegally-earned cash, and it's not fair to them for you to end up with it in your commissary account.
