Testosterone levels in the body increase when one hits puberty. Further, this triggers muscle growth, sperm making, and facial hair growth in boys. The pituitary gland controls the level of testosterone in the body and it releases a hormone called Luteinizing Hormone (LH) which signals the testicles to produce testosterone. Testosterone is the primary growth hormone, and thus these supplements are quite popular with athletes and body builders. However, these supplements need to be taken under a physician's guidance as they can have some irreversible side effects. These are also used by men who have a low sex drive as it is this hormone that is responsible for the male sex drive. In some cases, doctors prescribe testosterone injections if an individual has naturally low levels of the hormone. The problem is that the side effects caused by these injections are irreversible and when taken over a period of time, the body stops producing it naturally.
The bottom line is that these supplements make one bigger and stronger, by strengthening the bones and boosting one's energy levels. Body builders consume supplements to boost muscle growth as this is the fastest way to do so. Few experiments have even suggested that the use of these supplements after the age of 30 is beneficial for men. Tribulus is one of the most well-known booster of this hormone and is extracted from Tribulus Terrestris, a wine plant found in United States, Mexico, India, and China. Athletes use these supplements to improve their performance, but most of these are banned in competitive sports. Sometimes men over the age of 40 are affected by low levels of the hormone and it could be caused due to andropause or hypogonadism. In such cases, external delivery of this hormone is recommended. Some other diseases like type 2 diabetes or diabetes mellitus also causes depletion in the levels, and a physician may recommend testosterone therapy in such cases. Most bodybuilding supplements boost muscle growth and when incorporated with a good weight training workout, would give one a great physique in no time. Scientifically designed anabolic mineral formula 'ZMA' is widely used by athletes for its ability to increase hormone levels and strength. It is the most widely used testosterone for bodybuilding.
There are quite a few side effects of these supplements, and some of these are irreversible. So, one needs to consult a doctor before taking them. If they are consumed regularly over a period of time, they can stop the body's natural ability to produce this hormone. One of the most common side effects of these boosters is acne, as the intake of these supplements leads to oily skin. Baldness is also a major, visible side effect of this supplementation. Liver damage is attributed to the oral intake of the supplements and in some cases, prolonged use has known to cause liver cancer. Gynecomastia (man breasts) is an undesirable side effect of these boosters along with infertility and prostate problems. Some of the early signs of the side effects are prolonged and painful erections, along with swelling of arms and legs. Psychological side effects include constant irritation and increased aggression levels. Sleep deprivation and stress are some of the other side effects common to testosterone replacement therapy.
Some natural testosterone supplements in herbal medicines have no side effects, and a nutritious diet will also help you increase the hormone naturally. Regular exercise and healthy lifestyle routines are the easiest way to maintain and increase the levels naturally.
