Description:
Testosterone Cypionate is the longest-estered testosterone available today. It has a half-life in the body of 15 to 16 days and is found as injectable oil. Because it reacts in the body for so long, it can cause more water retention than other steroids and is best used as bulking compound in a stack.
As with all testosterone injectables, one can expect a considerable gain in muscle mass and strength during a cycle. Since testosterone readliy converts to estrogen, the mass gained from this drug is likely to be accompanied by quite a bit of water retention. The resulting loss of definition of course makes cypionate a very poor choice for dieting or cutting phases. The excess level of estrogen brought about by this drug can also cause one to develop gynecomastia rather quickly. Should one notice an uncomfortable soreness, swelling or lump under the nipple, an ancillary drug like Nolvadex should be added immediately. This will minimize the effect of estrogen greatly, making the steroid much more tolerable to use. The powerful anti-aromatases Arimidex, Femara, or Aromasin are yet a better choice. Those who have a known sensitivity to estrogen may find it more beneficial to use ancillary drugs like Nolvadex and Proviron from the onset of the cycle, in order to prevent estrogen related side effects before they become apparent.

Applications:
Testosterone cypionate is a steroid hormone from the androgen and is found in mammals and other vertebrates, testosterone cypionate is primarily secreted in the tests of mails and the ovaries of female, although small amount are also secreted by the adrenal glands, testosterone cypionate is the principle male sex hormone and an anabolic steroid.
Testosterone cypionate plays a key role in the development of male reproductive tissue such as the testis and prostates.in addition , testosterone cypionate is essential for health and well-being as well as the prevention of osteoporosis, testosterone cypionate is conserved through most vertebrates, although fish make a slightly difference from called 11-ketotestosterone.
It is also important to remember that the use of an injectable testosterone will quickly suppress endogenous testosterone production. It is therefore mandatory to complete a proper post cycle therapy, constisting of HCG and Clomid or Nolvadex at the conclusion of a cycle. This should help the user avoid a strong “crash” due to hormonal imbalance, which can strip away much of the new muscle mass and strength. This is no doubt the reason why many athletes claim to be very disappointed with the final result of steroid use, as there is often only a slight permanent gain if anabolics are discontinued incorrectly. Of course we cannot expect to retain every pound of new bodyweight after a cycle. This is especially true whenever we are withdrawing a strong (aromatizing) androgen like testosterone, as a considerable drop in weight (and strength) is to be expected as retained water is excreted. This should not be of much concern; instead the user should focus on ancillary drug therapy so as to preserve the solid mass underneath. Another way athletes have found to lessen the “crash”, is to first replace the testosterone with a milder anabolic like Deca-Durabolin. This steroid is administered alone, at a typical dosage (200-400mg per week), for the following month or two. In this “stepping down” procedure the user is attempting to turn the watery bulk of a strong testosterone into the more solid muscularity we see with nandrolone preparations. In many instances this practice proves to be very effective. Of course we must remember to still administer ancillary drugs at the conclusion, as endogenous testosterone production will not be rebounding during the Deca therapy.
