For many years DHEA, or dehydroepiandosterone, was considered a "junk" hormone, since researchers could not attribute any specific function to it. In the past few years, DHEA's image problem has been totally refurbished. It is the most abundant hormone in humans and other mammals, and it plays a critical role in many different bodily functions. In fact, decrease in DHEA levels is being increasingly used as an indicator of reduced immune response, loss of libido and lack of a sense of general wellbeing. Clinical studies over the past ten years show that DHEA may be the most critical single chemical in predicting health and disease.

The body produces DHEA in the adrenal gland using cholesterol as the starting material. It is metabolized to androstenedione, which is converted directly to testosterone. Like testosterone (estrogen in women) and other critical hormones, DHEA levels peak in the second or third decade of life, after which the decline begins. In men, roughly one-half of DHEA is lost by age 40. Reduced levels of DHEA mean reduced amounts of androstenedione, testosterone and other steroid hormone metabolites. It is interesting to note that as cholesterol in general increases with age, DHEA levels decrease. As a result, DHEA deficiency is associated with an array of chronic conditions, such as obesity, diabetes, high blood pressure, coronary artery disease, and various immune deficiencies, including autoimmune diseases.

Ultimate Nutrition's Crea Pure Creatine is the highest quality micronized creatine that is specifically designed to enhance biovoluminization. Crea Pure Creatine is scientifically tested to provide the ready source of energy for the athlete on the go.

The major challenge for athletes and physical fitness buffs is to keep the muscles and brain energized. This is especially the case for endurance athletes who also need to recover their muscle power quickly after an intense workout and exercise.

Muscle contraction and relaxation are driven by energy in the cells provided by the compound adenosine triphosphate (ATP). Muscles have only a limited supply of ATP, however. The ATP levels are rapidly used up during exercise, particularly in short, intense bursts of anaerobic activity. Many an athletes needs immediate replenishment of energy in the muscle during demanding regimens, such as sprinting and weightlifting. In these situations, the body produces ATP: The energy currency in the cells, which powers muscle movement and control.

To gain muscle weight you need a high caloric formula with a 2:1 ratio of carbs to protein and a proper exercise program. Massive Whey Gainer has over 30% high quality whey protein per serving. Many so called gainers are 5-10% protein, the balance, sugars. Massive Whey Gainer is the Ultimate weight gain formula on the market today.

Each nutritionally complete dose supplies your body with 55 grams of the highest quality (as measured by Biological Value, BV) peptide-bonded and free form amino acids, predigested complex carbohydrates (glucose polymers), pure crystalline fructose and U.S.P. quality vitamins. No soy protein or artificial sweeteners used. Find out what all the hype is about.

Body builders take protein powders to develop muscles. Weight lifters take extra protein to help them get stronger. People who are underweight take protein to gain weight. As people age, in general, they tend to lose weight. Protein is an excellent source of gaining weight in cases of both nutritional deficiency and weight loss for unknown reasons and, particularly, due to advancing years. Proteins are used in the production of skin, hair, muscles and bones. In addition, protein is used to manufacture hormones, enzymes, cellular messengers, and immune system components. Without adequate protein, the body does not have the ability to put cells, tissues and organs together.

Despite the central role played by proteins in all life processes, it is only recently that researchers have begun to understand the role of certain dietary proteins in muscle toning, immune enhancement and, in fact, in longevity. One particular protein has garnered considerable attention that is found in all milks called whey, which is processed to transform into whey protein concentrate. Ultimate Nutrition's Supreme Whey is the whey protein.

Protein is probably the most important supplement for all athletes, but it is especially indispensable for those involved in long-term, high intensity endurance training. It is the fuel for the build-up, mass and toning of the muscle. In fact, protein is essential for growth and development. The proteins that make up the human body are not obtained directly from the diet; rather, dietary protein is broken down into its constituent parts known as amino acids, which are the basic building blocks of life. That means that it is the amino acids, and not protein per se, which are essential nutrients.

Of the 20 amino acids that the body needs to make protein, eleven are designated as nonessential amino acids, because they can be produced by the human body from other amino acids and do not need to be obtained from the diet. The remaining nine amino acids cannot be synthesized by the body and are, therefore, called essential amino acids. These amino acids must be obtained by degradation of the dietary protein. All of these essential amino acids must be present in the body in order for it to build and repair muscle.
