Testosterone Cypionate is long acting formulation of testosterone which is indicated in the treatment of individuals who have absent or very low levels of the hormone. It is sometimes known as Depo testosterone.
The testosterone is esterified and thus is quite long acting. It is only available in an injection form. The anabolic steroid is typically dissolved in sesame or cotton seed oil and injected into the buttock area. The drug is slowly released from the injection site for about 7-12 days.
The formulation comes as white milky powder and is insoluble in water but freely soluble in most organic solvents including vegetable oil.
The body normally makes sex hormones like testosterone which is responsible for the normal growth and development of the secondary sexual features. This includes growth of the prostate, testes, penis, scrotum, body hair, vocal cord thickening, alterations in body fat and musculature. When testosterone deficiency occurs, the secondary sexual characteristics and body growth is always abnormal. Thus, one of the indications of testosterone therapy is in the treatment of individuals who lack testosterone or are infertile.
Indications for use
Testosterone Cypionate is used to treat conditions in made where there is a failure of testosterone to be secreted like:
primary failure of the testes to make the hormone
failure of the pituitary to release Gonadotropins
Testosterone and its analogues are widely used by athletes and bodybuilders. The steroid is taken principally to enhance the body and stimulate the psyche. Most bodybuilders who take this drug claim that it causes spontaneous bursts in energy associated with increased aggression. This feature of the drug is used primarily by weight lifters and professional wrestlers. Many athletes also claim that the drug improves their ability to perform exercise at intense levels.
Testosterone has moderate anabolic properties but also is a powerful androgenic agent.
Because the drug is given by an injection, its effects on the body are not rapid. One may not see any effects for at least 3-4 weeks after starting the injections. Unlike the oral testosterone, the injected formulations last a longer in the body.
When taken for more than 4-6 weeks, it can increase body mass and protein anabolism. However, for the body to build muscle one also has to eat a diet rich in calories. Most bodybuilders also take a combination of other hormones at the same time. Because testosterone is converted to estrogen in the fatty tissues, there is always the chance of developing gynecomastia and water retention. To prevent this, most bodybuilders add Arimidex or tamoxifen during the off cycle.
During testosterone injections, the natural body testosterone release is inhibited by feedback mechanism through inhibition of pituitary LH. At large doses, even spermatogenesis can be impaired. To allow for the hypothalamic-pituitary axis to recover, it is highly recommended that the drug be tapered off slowly over a period of a few weeks. Sudden discontinuation of the drug can lead to extreme fatigue, weight loss and susceptibility to fractures.
There are some individuals who should avoid testosterone like steroids because it can worsen the clinical condition. These conditions include:
those with allergy to the drug
males with breast cancer
males with prostate cancer
Women who are pregnant or breast feeding
Individuals who have liver, kidney or heart problems
When Testosterone Cypionate is injected at low doses, the side effects are rare. However, long term use is known to be associated with a varied number of side effects – all of which are reversible when the drug is stopped. For the female who decides to take testosterone, there are virilizing side effects which are not always reversible when the drug is stopped. Like all anabolic steroids, testosterone also has a number of side effects which includes:
abdominal cramps, diarrhea
ncreased /decreased libido
acne, oily skin
mental change including anger, depression, insomnia
loss of hair
When taken by females, the drug definitely can cause virilizing effects like:
deepening of voice
excess hair growth
irregular menstrual cycles
Testosterone Cypionate is converted into estrogen in the fatty tissues. The estrogen than leads to development of breast enlargement and water retention. This effect is typically seen after the steroid has been used for more than 4 weeks. The gynecomastia does reverse when the steroid is discontinued.
Over dose with Testosterone Cypionate is very rare. The drug is usually administered as an injection. If excess dose is injected, there are no acute side effects but the individual may feel sick for a few weeks. Depending on the dose injected, a visit to the hospital or a physician’s office would not be a bad idea.
In clinical medicine, Testosterone Cypionate is administered as an injection. The oily suspension is injected only into the muscles. Testosterone Cypionate is available in two strengths 100mg/ml and 200 mg/ml. It is only made for intramuscular injection. The drug can be injected into the buttock area once every 7-12 days. The majority of the Testosterone Cypionate is bound to protein and only 2% is free. The drug is supposed to be injected once a week, but there are some bodybuilders who do inject it every other day.
This is not recommended and can lead to the formation of abscess, sores and skin infections.
The injection site needs to be rotated if the injections are to be continued for a long time. The oily suspension should not be injected into the arms or the abdomen. The dose of Testosterone Cypionate ranges from 50mg-400mg/week, depending on the condition being treated. Bodybuilders tend to inject the higher amount of the drug- 200mg-400mg/week. The drug is then slowly absorbed into the blood stream over the next few days.
