Testosterone cypionate profile


Testosterone cypionatethis is one of the longest ester of testosterone available today. Its half-life in the body is approximately 15 to 16 days ( half-life 6.8 days). The drug is available in the form of an oily solution. Because it operates over such a long period of time, it can cause water retention to a greater extent than other anabolic steroids. Most often, it is used in the combined set of cycles to muscle mass.

In the body, testosterone cypionate acts like the natural hormone testosterone – a male sex hormone that is responsible for many of the physical and emotional quality of men. It causes deepening of the voice, sex drive, aggression and muscle growth. Testosterone operates through anabolic receptors, causing the muscle to retain more nitrogen, which, in turn, are the muscle proteins.

Testosterone cypionate disadvantage is that it is flavored, or in other words is converted into estrogen . When in the male body produces too much estrogen begin to appear feminine traits: gynecomastia , water retention, fat deposition on the female type, and there is a decrease in sexual desire and testicular atrophy . Most of the undesirable effects can be avoided if you use the drug correctly.


The rate of elimination from the body is comparable with enanthate

Especially prevalent testosterone cypionate in the United States. Although Testosterone enanthate is produced at an increasing rate around the world, cypionate is produced mainly in the United States. It is therefore not surprising that American athletes often use it it in their practice.

Many argue that the American athletes preferences have less to do with the greater availability of cypionate, compared with other esters, as with his great anabolic effect. Disadvantages of the drug, including fluid retention can be eliminated by antiestrogens .

If we compare testosterone cypionate or enanthate objectively, we can conclude that these two steroids are interchangeable, and cypionate is essentially no better. Both long-acting oil-based injection administered. This allows you to maintain a high level of testosterone for about two weeks. Enanthate may be more preferable from the viewpoint of free testosterone release form, as in the air on one carbon atom less (duration of action of testosterone esters is greater than the longer chain ester). Despite the stormy arguments on forums, in practice, the difference is very small, so the choice may be dictated by the availability of more than pharmacological properties.



As with all injectable form of testosterone cypionate is a significant increase in muscle mass and strength during a cycle. Because testosterone is easily converted into estrogen, about 30% of the mass is accounted for fluid that is lost quickly after the cycle.

For this reason, testosterone cypionate is not very suitable for the cycle. Excess estrogen levels caused by this drug can lead fairly quickly to the development of gynecomastia, which is manifested as pain, swelling or induration at the nipples. To prevent this, use ancillary drugs ( Nolvadex and Clomid ). Antiestrogens minimize the effects of estrogen, and reduce the action of anabolic steroids in the directional direction. It is best to use aromatase blockers.

Since testosterone is the primary male androgen , we can also expect the development of pronounced androgenic side effects . Their expression is largely related to the rate at which the body converts testosterone into dihydrotestosterone (DHT). This substance is a metabolite of testosterone, which is responsible for the development of certain androgenic effects that are associated with the use of testosterone cypionate. These include: increased secretion of sebum, acne , hair growth on the body and face, as well as male-pattern baldness.

color of hair loss is not expressed at all. Worry about it should first of all those who have a genetic predisposition (the case of baldness in the family). To prevent this side effect, the drug may be used Propecia (Proscar), which blocks the conversion of testosterone to dihydrotestosterone. Propecia significantly reduces the risk of alopecia, and reduces the likelihood of remaining androgenic effects.


Despite the fact that the duration of action of the drug is quite large, injections are performed once a week, to keep the concentration constantly high.

The average single dose is 250-500 mg per week, with a view to gaining lean muscle. The drug gives good results during the cycle of “solo”. Experience has shown that higher doses of 800-1000 mg does not lead to better results, but sharply increases the risk of side effects.

As noted above, to block the action of estrogen should be used tamoxifen (10 mg per day, starting from the second week of the cycle, and ending his welcome after 2 weeks after discontinuation of testosterone). A more preferred embodiment: use during the cycle of Proviron. After administration of testosterone Proviron should be replaced by Tamoxifen, to restore the secretion of testosterone. The use of anti-estrogens reduces the accumulation of fluid in the body and suppresses the development of gynecomastia. Be sure to read the article about the PCT .

If the rate exceeds the duration of 4 weeks, use of gonadotropin of 500 IU, 1 times a week throughout the cycle ranging from 3 weeks.

Combined Cycle

Combined testosterone cypionate cycle is not much different from the “solo”. The drug is often combined with nandrolone 200 mg per week. Cypionate average dosage of 200 mg per week.
