Is there an upper that looks very similar to black tar heroin?

I got this stuff that I was told was black tar heroin and it looked like it so I bought it.i shot it up and I felt like I just shot crack, not a downer of any kind. I am so confused...all I had to do was apply water and heat like I would with tar..and it was the same consistency as tar..can any pls help me out and possibly come up with an explanation for this?
