What got worse for some people
In their own words
“Yes that work but still don't have enough energy for training.. well clearly you gotta stack mots-c. Yeah but after mot-c I feel nervous and anxious.”
“Mots-c hands down. Great for energy and mitochondria repair and rejuvenation. I get tons of energy but doesn't keep me awake.”
“Took my first dose of Mots-C yesterday morning and felt great all day. Unfortunately, I could not sleep at all last night.”
“I am in week 3 and taking it every 3 days and I feel completely shot. A lot of fatigue and feeling much weaker during workouts.”
“Mots-C has also shot my cardio/lifting endurance through the roof even when in a large calorie deficit I still feel energized.”
“Now I'm on week 3 of 5mg every 5 days of MOTS-C and definitely noticing body comp changes. No sleep issues at the lower dose.”
