I had these 2 nights ago. (the ones with some tiny beige specks in it). They were really good, but weird. I only had one, but it was my first pill in 10 months (i used to take them heaps, but stopped). Anyway, i did it with 2 friends who take pills a fair bit. It came on REALLY strong really suddenly, and me and my friend both got really panicky which I have NEVER felt before, not even on psychedelics. It was just not a pleasant feeling at all, and i felt really worried and uncomfortable. I made myself throw up to get it out of my system, but it was too late. But I told myself to get a grip and chill out and have a dance and it got much better, and I started enjoying it a lot. It was REALLY strong but I didn't feel that euphoric- although I think that's because we just took it at my friends house, not at a party or club or anything. I think if I had it in a different environment it would have been really good. It lasted a really long time- took it at about 3am, and was still feeling it well into the morning. There was no comedown at all, which makes me think it was a very clean pill
