Testosterone Decanoate CAS 5721-91-5 :
Testosterone Decanoate, combination of Testosterone and ester Decanoate, is androgenic steroid with a pronounced anabolic effect. This hormone is an extremely effective bulking agent, and in fact is one of the best muscle-builders known. It will cause an increase in IGF-1 levels, Red Blood Cell count. Testosterone Decanoate is subject to aromatization as well as 5alpha-reduction, which are the pathways through which testosterone is converted to estrogen and dihydrotestosterone respectively.
PCT plan essential
Testosterone use will quickly shut down the bodys natural production of the hormone, thus making a proper PCT plan essential for restoring the bodys natural function and maintaining gains as best as possible after use of the steroid has been discontinued. At cycles end, bodybuilders often choose to use a combination of Clomid, Tamoxifen, and HCG for a period of 3-4wks in order to restore pituitary gland and testes operation quickly and effectively.
Woman bodybuilders often use testosterone to build mass, although of course the dosage is significantly less than what males would use due to the possibility of masculizing side effects.
Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
