All medications are required to have an imprint which allows the ability to identify what they are. The only exceptions are herbal preparations and vitamins. I have no clue what this is. You could take it to an herbal store and ask them if they've ever seen it before. I'm certain it is not a commercially manufactured medication. Good Luck!
IM A YOUNG ADULT USER. and what i may beleive is that there is a concerta er (extened relaease). Normally they come in a gray plastic coating and will be scratched or washed off to release the medication all at once. but the ones i have seen and done look EXACT:Y like thoes. hope this help
