Did a pill identifier and it said it was a hydrocodone 10/500mg. Did further reveiw and it said Hydocodone would have imprinted a M636 on it. Now I am confused on what I found. To make it worse a pharmasitis says it has Caffine, Ace something and a drug like morphine in this pill. Pill identifier said nothing of the sort so please help this confused girl out. Thank you.
