My friend took a Blue Ninja Star last night.
Was a circular pill, that was blue-colored but looked like it was originally a white pill (blue specs everywhere)
Has a ninja star impressed into it. To me it looked like a pipe pill, which is why I was too scared to consume it, but my friend who did consume it said it felt like a decent roll (but weaker than the pokeballs that he took later). Honestly I still am not sure he truly feels and understands the difference between MDMA and Pipes, but I have educated him and he said they weren't pipes, but I still question that.
Overall: I'd be sketchy of Blue Ninja Star's. Hit or miss if you get pipe, and if it's not a pipe pill, it still doesn't sound like a great pill.
