Hey guys. SWIM bought pills from a friend. The friend said they were ritalin. He showed SWIM the container they came in. The prescription container said "Methylphenidate Hydrochloride - 5mg". The pills are approximately 4 mm in diameter, round, and pink/orange. Kind of the same color as gravol. On on side it says 130. The other side says MP with a line under it that divides the pill in half and under the line it says 5. SWIM assumed they were real because SWIM thought MP stood for methylphenidate. SWIM also thought the "5" meant 5 mg, and it said 5 mg on the prescription container. SWIM took 4 and nothing happened. Please tell me what these are. Thanks
