Really like this creatine. Easy to take. No mixing needed. Results are very noticeable within a week for me. My muscles feel more firm have more explosiveness in my trainings. Also I feel less sore the day after a good work out.

As an MMA fighter, I need every advantage I can get in the ring. Fighters Knockout has given me the extra energy and focus I need to dominate my opponents. I've noticed a significant improvement in my reaction time and speed, and I'm able to maintain my intensity throughout the entire fight. This is a must-have supplement for any serious MMA athlete.
