In people

People on MOTS-c most often notice more stamina and less fatigue in workouts within two weeks, with a bit of warmth or flushing after a dose at first. Fasting blood sugar and post-meal crashes improve over the following weeks, and waist size eases. Older users report easier stairs and walks. Inside the body, exercise itself raises MOTS-c in muscle and blood; the vial adds to that same signal.
