MMUSA Cyclist-Optimized Creatine Serum. Amplifies Cycling Sports Performance, Boosts Nitric Oxide Levels, Stamina, Energy, Endurance & Focus. Fights Fatigue & Lactic Acid Build Up. Cherry, 5.1 Fl Oz

Mainly use the serum when running more than 10 miles, and as advertised, it helps me go the extra miles without feeling fatigue and exhausted. Since I am taking the drops while drinking water it goes in smoothly, taste great and do not have any side effects. Highly recommend this product for long distance runners.

I have used this product for months. I take it 10 minutes before I arrive at the Gym. It works for @45 minutes, and can deliver high intense energy work out.

I purchased this product in hopes of getting slight boost in my endurance and performance while cycling. Tried it more than several times, with no visible results. The only thing good about this product was the taste.I realize that everyone’s physiology is different, but this product did absolutely nothing for me. A waste of 30 bucks.

OK
