If you want to know that the drug you brought from the store are original or duplicate is just by easy 3 steps. Behind the each medicine there is one seven/eight number which is the batch number, just message that number to 9901099010, after 10 sec, you will get one response message. If the medicine is original then you will get the reply with the proper batch number and the name of the pharma company. which you can cross check with your strips or any medicine which you bought. and if the number is not matching then you just have to resent the same message so the complaint will be registered. Please share with all.
