what kind of concentrate do i have?

Hey guys, im kinda new here i'd guess you'd say. I've had my account for a while just browsing but I never really post. Anyway, I have a question about hash oil. For a while I've been dabbing this black, very sticky, kinda hard to manage oil that my friend had. This was the first oil I was ever introduced to so it's really the only one I've ever known. Well, I've been researching for a while trying to learn more about the whole oil scene, because it's becoming more popular around me, but I'm still kinda new to the whole thing. I managed to get my hands on some stuff thats much lighter and different looking, kinda greenish in color. Haven't been able to dab any of it yet, but it looks much more manageable than the old stuff I had. From what I've read and such it seems like this is a much better concentrate. I'll be dabbin some of it tomorrow, but I just wanted to see what ya'll think I have
