I recently came into possession of some bk-mbdb from a somewhat dubious vendor(Had some bad some good feedback was hard to tell what was real and what wasn't). Anyways I have had experience with Methylone and was expecting something very similar to it(I had heard some people thought it was better than Methylone). Well I took 200mg and he never felt that same peak he got every single time with Methylone. The strong head rush OH GOD I FEEL SO GOOD. He felt good and talkative and speedy. Music sounded great but he never got that peak. Is this normal for this substance at all?
