Like what is done differently to it? I've noticed the hard stuff is not as potent as the gooey sticky heroin
It's impossible to say, but presumably there's different amounts of material that are not heroin (e.g. cuts)
It is impossible to say with confidence how pure a sample of dope is based upon looks/taste/smell/consistency.
But, gooey stuff can be frozen and dried out and made dry.
