Hi hiren Hope you're doing good buddy There is nothing called as a chemical Rp... Its only original and other made By tantriks which again is hard to believe As far as my knowledge is concern If the rice colour is blue then Its a dp and only the final Checker can differentiate if the Rp is og or no There are certain things which are kept Concealed by the company only The final check knows them
