It depends who you are dealing with... If your dealing with literal street dealers then yes, but if you know some guys up top then no.
When the heroin comes in, at least 12 years ago or so, it was all very similar in purity and potency. It’s not until it gets broken down and distributed that the need for branding is important to help keep track of batch potency.
For me, there was no names or branding. You couldn’t spend less than 100$ but they preferred to sell grams. A gram of pure uncut #4 heroin isn’t cheap lol. I’ll never forget my first gram, lasted me weeks.. Also each time was negotiable, it was all about how much product was in supply and how much was needed at the time.
