This pharmaceutical grade creatine is as "straight from the source" as it gets.
Supplement creatine to naturally increase strength, power, endurance, and recovery. The body uses creatine to create the energy you need to make it through that rough training session (and simply make your muscles contract) - ATP. A product of three different amino acids (the building blocks of protein, and eventually muscle), creatine is essential for those hoping to improve either aesthetic or performance qualities.
More creatine available = faster ATP replenishment. Faster ATP replenishment = longer, more intense training. Knowing this, creatine supplementation is a no-brainer.
