This news story is a bit old:
But they talk about cyclopropyl fentanyl being seized in counterfeit tablets and this is the first time I have ever seen cyclopropyl being mentioned. In fact I have never seen it for sale.
THIS IS NOT FOR SOURCING But has anyone else seen it for sale? I'm asking because I wonder if someone is just putting this shit into bags and selling it as a different fentanyl. As if fentanyls are not dangerous enough, switching from something someone ordered and researched (hopefully) is just flat out bullshit.
TL/DR Anyone ever seen cyclopropyl fentanyl for sale?
What's the difference between all these different fentanyls? Is it just potency?
