ahh...I had one of them once but it was speed...Very very fucked up...the high was like 7 hours instead of 4 that average pills give me.
I never did mind a decent speed cut, especially if your feeling active, just means you can't go overboard with the batch, risk overheating etc.
Me and some buddies had some music notes about a month ago. They looked exactly like those, but more blue. It was the worst E trip I have ever had. It lasted soo long, and it was extremely unpleasant, speedy, and paranoia-filled. Nothing like a real ecstacy. Uhhh I hope no one has to experience those things ehh. Im sure yours were different though.
