Creatine Monohydrate

Creatine is an amino acid. It is normally produced in the body from arginine, glycine and methionine. Creatine plays a vital role in cellular energy production as creatine phosphate (phosphocreatine) in regenerating adenosine triphosphate (ATP) in skeletal muscle. Without ATP, muscle contraction is not possible. Oral administration of creatine increases muscle stores and may increase muscle strength and improve exercise performance. In the diet, creatine is found in meat and fish - although cooking destroys most of it. Most of the creatine in the diet comes from meat (an 8-ounce steak might have a gram), but about half of the body’s supply is manufactured in the liver and kidneys. On average, your muscles require about 2 grams of creatine a day (somewhat more for muscular people, a bit less for skinny folks), but more or less depending on your activity level and degree of muscle mass

Creatine is stored in muscle cells as phosphocreatine and is used to help generate cellular energy for muscle contractions. It also may increase the amount of water that each muscle cell holds - thus increasing the size of the muscle (and possibly its function as well). Creatine is used in the body to produce creatine phosphate or CP, which can be thought of as a storage form of quick energy. The function of CP is to regenerate the primary supply of cellular energy - which comes from adenosine triphosphate (ATP). ATP supplies energy for all cells in your body. Upon giving up some of its energy, ATP becomes ADP (diphosphate) and needs to be regenerated back to ATP to do it all over again. CP performs this crucial ATP regeneration step by donating a phosphate group to ADP

Tribulus Terrestris

Tribulus (puncture vine) is a vine that has been used as a general tonic (energy) and herbal treatment for impotence, but is found primarily in dietary supplements marketed for increasing testosterone levels in bodybuilders and power athletes.

The idea behind tribulus is that it may increase testosterone levels indirectly by raising blood levels of another hormone, luteinizing hormone (LH). LH is a hormone produced by the pituitary gland and plays a role in regulating natural testosterone production and serum levels.

The active ingredient in tribulus is unknown, but is though to be a component known as furostanol saponins. There has been very little research conducted on the effectiveness of tribulus in elevating testosterone levels – the main claim made by body building products which contain the herb. In some cultures, the tribulus terrestris plant has been used as a "tonic" to in crease energy levels and treat sexual dysfunction (usually in males). In animals, tribulus may stimulate "mounting" behavior. Some European studies suggest that tribulus extract can increase testosterone levels 30-50% above baseline levels – but still well within the normal range. Unfortunately, however, these same studies also suggest a similar increase in estradiol levels – not exactly what the hardcore muscle builders should be interested in boosting
