Welcome to Wikipedia. We welcome and appreciate your contributions, but we cannot accept original research. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. Thank you. Materialscientist (talk) 22:39, 19 April 2016 (UTC)

Please refrain from making unconstructive edits to Wikipedia, as you did at Methylphenidate. Your edits continue to appear to constitute vandalism and have been automatically reverted. Thank you. ClueBot NG (talk) 22:39, 19 April 2016 (UTC)
