Phosphagen is the original creatine monohydrate supplement so even though the name is now a little harder to spell, the product is the same high quality creatine that you have come to expect from one of the industries leaders, EAS.
The phosphagens are energy storage compounds, also known as high energy phosphate compounds, are chiefly found in muscular tissue in animals. They allow a high energy phosphate pool to be maintained in a concentration range which, if it all were ATP, would create problems due to the ATP consuming reactions in these tissues. Muscle tissues will have sudden demands for lots of energy. These compounds can maintain a reserve of high energy phosphates that can kick in as needed, to provide this energy that could not be immediately supplied by glycolysis or oxidative phosphorylation.
The actual biomolecule used as a phosphagen is dependent on the organism. In mammals, the specific compound is creatine. Creatine phosphate, or phosphocreatine, is made from ATP by the enzyme creatine kinase in a reversible reaction. Phosphagen takes creatine transport to the next level with the addition of 4-hydroxyisoleucine, a compound that facilitates creatine transport by potentiating sugar-induced insulin secretion. This means that one can experience unsurpassed creatine transport with fewer sugars. Further, this compound may also increase creatine entry into muscle cells, as research indicates 4-hydroxyisoleucine may increase insulin sensitivity3. Ultimately, this means faster gains in muscle development and athletic performance while maintaining leanness.
ATP is an energy-carrying molecule found in the cells of all living beings. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes. Relevant to us - it is the energy store of the body, the direct fuel for all muscular activity. Energy is created with the release of a phosporous molecule from ATP, as it becomes ADP.
In a resting vertebrate muscle, the available supply of ATP can sustain maximal muscle work for less than one second. The muscle, therefore, must continuously replenish its ATP store, and this is done in many different ways. One mechanism for the formation of ATP operates so rapidly that for a long time scientists were unable to detect any change in the amount of ATP. That mechanism is the release of a phosphorous molecule from creatine, facilitating the resynthesis of ATP, and the renewal of the muscle's energy store, effectivly allowing the muscle to operate longer at peak capacity.
As your ATP generation is directly linked to the amount of Creatine you have, the equation is simple - the more creatine you have, the more ADP you will be able to synthesize and thus the longer your muscle will operate at maximum power. This is what EAS Phosphagen HP aims for. Creatine thus isn't an instant-grow muscle-fix, but rather a supplement which enables an athlete to work out harder and longer, thus reaping greater benefits. Also, the creatine in EAS Phosphagen HP super-hydrates muscle cells, giving athletes the well-known pump look after workouts. Creating effects will be visible within two weeks on a vast majority of people.
