It's a square beige pill with a big R on the back and a 100 l MG on the front but the 100 is on top then there's a split line and then the MG on the bottom. I honestly have no idea what or where this pill came from, I already compared it to all the pills in my house but nothing matched, I am concerned that my friends boyfriend (they both live with me) has been putting it in my food when I'm gone because the pill (s) were found inside an oven mitt in my kitchen and he keeps a mortar and pestle inside his room and gets weird when anyone touches it.
