SR9011 VS SR9009 SR9011 VS SR9009 ,they play basically the same role when they are used for fitness. The only difference is their molecular formula. SR9009: C20H24ClN3O4S   and SR9011:C23H31ClN4O3S.We can see that SR9011 has more C3H7N1 than SR9009, and of course, an O is missing. From the above molecular structure, SR9011 has three more hydrocarbon chains than SR9009, and …
