Creatine, Tone..from a biology view
Maintenance of the right amount of tone requires the use of muscle spindles. Muscle spindles are a special muscle fiber with sensory nerves surrounding them. So what happens is the spindles contract with normal muscle fibers but they also send sensory nerve pulses to the central nervous system, which regulates muscle contraction so that tone is maintained.
As the intensity of nervous stimulation increases, more and more motor units (muscle fiber with motor neurons) are activated. Thes is known as recruitment, results in stronger and stronger contractions.
ATP (your body's basic energy) produced previous to strenuous exercise lasts a few seconds, and then muscles acquire new ATP in three different ways: creatine phosphate breakdown, fermentation, and cellular respiration. The first two are anaerobic, meaning that they do not need oxygen to function.
Creatine Phosphate is a high-energy compound built up when a muscle is resting. Creatine Phosphate connot participate directly in muscle contraction. Instead, it can regenerate ATP very quickly. It is the speediest way to make ATP available to muscles. Creatine Phosphate provides enough energy for only about eight seconds of intense activity, and then its gone. Creatine Phosphate is rebuilt when a muscle is resting by transferring a phosphate group from ATP (ATP means adenosine tri-phosphate) to creatine.
Fermentation also produces ATP however much less at a slower rate. It occurs when your body does not have enough oxygen to carry out cellular respiration and is the back up energy system so that when you run out of oxygen you dont collapse. Fermentation builds up lactic acid in the muscles making them tired. If fermentation occurs for two or more minutes then cramping takes place. The cramping is a lack of ATP needed to carry out some vital functions.
Cellular respiration produces most of the ATP in your body and is a highly efficient mean of energy production. Glycogen and fat are stored in muscle cells. If Oxygen is available, a muscle cell can use the gluclose from glycogen and fatty acids from fat as fuel to produce ATP.
Hope that helps someone out there someway...doubt it will but here it is.

ur wrong i it helps me with my thread, just posted. Oxyshot would works best, much more efficient. Im guessing it wouldnt hold water in your muscle like creatine to get a more pumped look, so what would happen if u took both?
