"There is a spelling error on package which is in most cases a sign of fake product... Original brands don't have spelling errors on boxAlso, I counted the pills... They were 119 instead of 120... But that is no problem.... It just gives off one more wrong signal about whether the product is genuine or notThese kind of mistakes don't happen in big brandsCan't say anything about pill quality right now... Will have to try more before writing the full review.. I will update later"
