I will not use an outline to this post. I'm here to warn you that this is almost definitely some kind of RC opioid (I'm not sure which one to be exact). Here's why it is:
1) SMELL - It hardly smells like vinegar.
2) TASTE - I dipped my hand in the bag and had a completely unique taste. It was somewhat bitter, but in a chemical way if that makes since. It tastes like a less strong version of tianeptine.
3) EFFECTS - When shot it does have a euphoric rush, then it fades away after 10 minutes into feeling disoriented. The effects don't last long of course.
That's pretty much all I can think of. Anyone have any idea what it is?
Edit: 4) OTHER
-I've been doing this all day (I'm a fiend) since noon and it is making me really mentally mushy.
-I also had 4mg of Suboxone today and it went through that.
OTHER REVIEWS (VENDOR FEEDBACK ON PRODUCT
"This is mostly fent...strong initial rush with no legs...for the price not bad..for fent that is"
"FENTANYL WARNING BEWARE!"
"Tast sour but never tasted H like this [...]"
Yeah, fent has NO euphoria.
Pure dope (diacetylmorphine HCl) is supposed to be the whitest white powder, clear in a solution, with no vinegar smell (as the acetylation of the morphine will be done properly without excess of the acetylation chemical left).
Sounds like it could possibly dope mixed with U-47700, judging by the euphoric rush followed by disorientation + quickly fading effects.
Hell lol, could be plain U-4 with a "vinegar" taste added to it.
Also, U-4 can break through sub quite easily, from my own experiences and anecdotal evidence I've read.
