Testex-250 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.
Testosterone is the male sex hormone responsible for many of the physical and emotional traits of men. It creates the deeper voices, sex drive, aggression and, of coarse, larger muscles in men. Testosterone makes the muscles retain more nitrogen, which in turn makes the muscle synthesize proteins better, producing larger muscles.
The downside to testosterone steroids is that they aromatize, or turn into estrogen, in the body. When the body has too much estrogen it begins to take on female characteristics gynocomastia, water retention, fat gain, loss of sex drive and testicular shrinkage are all most certain side effects of taking testosterone and letting it aromatize in the body.
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. 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.
