I've never bought H before because of fear of fentanyl cuts but my U-47700 usage is starting to decimate my nose and I'm already iffy on lack of research. I ALWAYS test all my shit with several reagents but I've heard it's hard to test for fentanyl and fentanyl analog cuts since there is so much more heroin than fentanyl by weight. My area also had a big OD problem and I suspect it's due to potent cuts.
How safe is most DNM heroin? If I buy good product from reputable dealers should I worry? Has there been any recorded cases of potent cut heroin on the dnms, and if so is it at all common?
EDIT: Main reason I'm looking into H is to get off u-4. Safety profile is still relatively unknown but I'm hearing some not so great things and my nose is already getting destroyed so I'm looking into alternatives. For the most part pills are too expensive and I only trust them marginally more than H for cuts (since they're probably pressed anyways, right? Only have experience with alorazolam bars as far as DNM pills go) so H is my only feasible alternative
If you feel iffy about it, just don't do it bro. Your life is so much more important than a high.. I know there are good vendors out there but fuck man, love yourself I'd hate for something to happen to you. ily <3
