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 -NH-(amine group) replaces -O-(carbonyl group). This makes SR9011 VS SR9009 is more bioavailable and has a longer half-life.
