I take motsc, nad+, and ss31 all at once. I'm not sure ss31 does anything noticeable for me. I use ss31 fasted before bed and motsc with nad+ fasted in the morning ahead of a fasted workout. The workouts feel strong.
I'm currently using a combination that includes reta, tb, bpc, cjc/ipa, and mots. I've taken 1.5 mg of mots before workouts Monday through Friday for a month now, but I'm considering a couple months of ss31 to support mitochondrial repair. I want to know if I can keep the mots going during the ss31 protocol or if that would simply be pointless.
