Testosterone steroid is the natural substance - major androgenic hormone produced
by the interstitial cells of the testes. It regulates gonadotropic secretion and wolffian duct
differentiation and stimulates skeletal muscle. It is also responsible for other male characteristics.
Testosterone steroid possesses protein anabolic properties, and it plays an important role in
maintaining muscle mass and bone tissue in the adult male. Testosterone steroid has two different
effects on the body: anabolic effects which promote growth and muscle building, and androgenic
effects which develop the male sex organs and secondary sex characteristics such as deepening
of the voice and growth of facial hair. It can be prepared synthetically from cholesterol or isolated
from bull testes, used in the form of various esters in treating male hypogonadism, cryptorchidism,
and the symptoms of the male climacteric; its derivatives may be used for their anabolic properties;
also this drug may increase woman sexuality. It is also used to treat impotence (erectile difficulty,
or the inability to attain or maintain an erection) and other male sexual problems when they are
due to low testosterone levels.
The most common forms of testosterone are:
• Testosterone cypionate
• Testosterone enanthate
• Testosterone propionate
• Testosterone undecanoate
• Testosterone suspension
• Testosterone transdermal (gel,patch or cream)
• Depo testosterone
Testosterone cypionate, Testosterone enanthate, Testosterone propionate, Testosterone
undecanoate, Testosterone transdermal and Depo testosterone contain chemically bound testosterone
in the form of ester. Only testosterone suspension contain free base of testosterone.
The usual adult dose of testosterone in men is 100-400 mg injected every 3 to 10 weeks in the
gluteus maximus muscle (buttocks). For men and women the recommended dose to achieve anabolic
(muscle or bone-building) effect is 200-400 mg injected every 3 to 4 weeks. Low levels of testosterone
can cause symptoms of fatigue, malaise, loss of sex drive, and loss of muscle tissue. These symptoms
can often be treated with synthetic testosterone. Hormone replacement therapy with synthetic testosterone
steroid may help to relieve symptoms of fatigue, muscle wasting, low sex drive, impotence, and
loss of facial or body hair. Women may also develop low testosterone levels and experience symptoms
of fatigue, loss of sex drive, and a decreased sense of well-being. Testosterone therapy can help
them too. In the case of bodybuilding short cycles (6-8 weeks) are often the most beneficial,
in order to minimize potential side effects and maximize potential benefit. Often the most muscle
gain occurs in the first month of the cycle. People should not use testosterone if they have:
diabetes, prostate troubles, serious heart or kidney diseases, excess calcium in the blood or
if you are pregnant or trying to get pregnant. Some side effects can occure when this drug is
used for a long time: Men: frequent or continuing erection, low sperm count, breast enlargement
(breasts usually return to their original size when medication is stopped), frequent urge to urinate.
Women: enlargement of the clitoris, deepening of voice, unnatural hair growth.
