    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.

    This product is a synthetic androgen, mainly used in the clinical treatment of infertility or infertility, cryptorchidism, functional uterine bleeding, menorrhagia, endometriosis, uterine fibroids, climacteric syndrome, metastatic breast cancer and ovarian cancer, pituitary dwarfism, senile osteoporosis, aplastic anemia.
