Okay, so I got some pills from a buddy and he told me what they were but I forgot (and he didn't know how to spell it anyway), but it's some sort of ritalin or adderall or something but specifically for adults and I know it starts with an "S" and it has some t's in it, but I can't find it on the internet. It's a capsule and it's half blue, half white. On the blue half it says in cursive "Lilly" and right below that "3228", and on the white half it says "25 mg". Any ideas? Your input is greatly appreciated!!!
