I ran SS-31 for 6 weeks and then Mots-C. I'm following the 14-week protocol that you can find here. It's been posted several times. The thesis is that SS-31 rebuilds the function of any damaged mitochondria and the Mots-c then recharges and optimizes them. I also take 600 mg of NR daily. I didn't feel much on the SS-31, although many do, but Mots-C is like rocket fuel so maybe SS-31 did it's job. The protocol specifies 5 mg of Mots-C on MFW for 6 weeks, but I had to drop to 3 mg because it was just too much, although I may try 5 mg again after some time at 3 mg. The protocol was on aged rats, which corresponds to older people, of which I am one. Younger people may not get the same results because they haven't incurred the damage that age brings.
