Testosterone is a steroid hormone made by the testes that stimulates the development of men sex characteristics and manages male reproduc-tive function. That is called the best muscle-building hormone because it does just that-builds muscle and strength fast. Testo-sterone increases muscle protein synthesis and net muscle protein balance, result-ing in increased muscular mass. "Testosterone is one of the most effective hormones for burning body fat in both men and women, " states Dr . Ullis. Signs of low testosterone levels include low energy levels, muscle weakness, depression, and sexual dysfunction. Too much testosterone in males can convert into dihydrotestosterone (DHT), which can have adverse effects on the prostate gland plus cause tresses loss, and estrogen, aromatization of which can business lead to water retention, increased fat storage, and gynecomas-ha in males. It is important to measure both "free" testosterone (the lively form) levels and estrogen levels to ensure there is not too much estro-gen being produced. Estrogen can halt your muscle-building initiatives.
Below we have listed the supplements for bodybuilding that will provide the highest Testosterone-Boost from clinical studies.
um ZMA(R). ZMA is a highly specific and unique vitamin and mineral com-bination. There are certain mineral deposits that contain a positive impact on athletic performance as well as testosterone levels. ZMA is a special com-bination of zinc, magnesium, and vitamin B6. Test Boost Elite Zinc is involved in the action of several human hormones, including insulin, growth junk, testosterone, and estrogen, and in more than 200 enzymatic reactions. Research has pointed out that exercising individuals have a greater need for zinc and are more prone to a zinc deficiency. It is proven to increase testosterone levels in healthy subjects. A 1996 study showed that taking 30 mg of additional zinc daily by healthy men experiencing moderate zinc defi-ciency doubled their testo-sterone levels in a six-month time frame. Magnesium is involved in over 300 enzymatic reactions in the body, including glycolysis, the Karzinom cycle, creative phosphate development, nucleic acid synthesis, amino acid activation, cardiac and smooth muscle contractabil-ity, cyclic AMP formation, and, most of all for strength athletes, proteins synthesis. Vitamin B6 is also known as pyridoxine and has some major implications in protein activity. The coenzyme form of this vita-min is of a vast number of nutrients, the majority as part of amino acid metabolism. B6 is necessary in glycogen catabolism to "unlock" carbohydrate energy and it has also been shown to diminish the actions of certain catabolic steroids, such as glucocorticoid hor-mones (cortisol). This can boost the testosterone-to-cortisol ratio, lead-ing to positive muscle-building effects. This device has been also combined with HMB supplements to improve the effects.
The zinc in this product is specifically formulated as zinc aspartate and zinc mono-L-methionine, which makes it more bioavailable. The magne-sium is in a chelated form sure to aspartate, which boosts its bio-availabity. Research with ZMA conducted on strength athletes demonstrates this mixture of zinc, magnesium, and vitamin B6 can increase total and free testosterone levels by 30 percent. A study published in Medi-cine and Science in Sports and Exercise showed that nightly supplemen-tation with ZMA also increased durability and power. Taking one dose of ZMA about thirty minutes before bed time highly recommended.
? Tribulus Terrestris. This herb, used in Ayurvedic medicine, is also known as puncture vine and contains been used as a testosterone booster to increase levels natu-rally through a unique mechanism. It stimulates leutinizing hormone (LH) manufacturing from the anterior pituitary gland, which in turn stimulates testosterone production. Scientific studies have shown that Tribulus can enhance LH and free testosterone levels in healthy subjects by 70 per-cent and 40 percent, respectively. A Bulgarian study revealed that more than 200 men enduring from impotence-which is often caused by low androgenic hormone or testosterone levels-showed improved testosterone and LH levels as well as sperm production after the subjects supplemented with a prepa-ration of Tribulus terrestris. The research also shows it to be very safe. It works at a divided dosage of approximately 750-1, 500 magnesium daily; good times to take it are initial thing in the morning and one hour before a workout.
? Eurycoma Longifolia. The main of this herb, commonly known as Tongkat Ali in Malaysia, has already been used for centuries for treating fatigue, loss of sexual desire, and impotence. Plenty of research shows that it boosts sexual function as well as sexual interest. Several human studies also show that it may enhance testosterone levels through various mechanisms. The lively ingredients include glycosaponins and eurypeptide compounds. Recent human being clinical trials have shown that Eurycoma products from HP Ingredients and patented LongjaXTM increase IGF-1 levels and modulate natural testo-sterone and cortisol levels. The bioactive eurypep-tides appear to boost interest in sex and functionality, in both men and women, by increasing testo-sterone levels and inhibiting sexual intercourse hormone-binding glob-ulin (SHBG), so that more free testo-sterone remains in blood. Individual clinical research conducted by Dr. Ismail Tambi, from the Specialist Reproduction Analysis Center, in Malaysia, has confirmed that LJ100 boosts serum testosterone and DHEA levels and decreases SHBG lev-els significantly. Eurycoma holds promise for boosting testo-sterone lev-els and bettering common health. Recommended amounts range from 100-300 mg in divided doses daily.
