Testosterone undecanoate (TU) is a recently developed steroid which was designed in an effort to create an orally available testosterone product that isn’t toxic. The demand for this type of product has been great since most oral steroids can’t be taken for long periods of time, yet many users who are on HRT programs dislike needles and having to take injections to sustain their testosterone levels. The design of this steroid is so that it is to be delivered to the blood through the lymphatic system by bypassing absorption by the liver and being taken in as a fatty oil from the digestive system by the lymphatic system. This is why the preparation of this drug comes in oil filled capsules. This is an innovative idea which was first used in the creation of the unsuccessful steroid quinbolone. However, there is a much higher demand to sustain a drug such as TU due to the fact that testosterone has a much more profound use in medicine than does boldenone. The system in which TU was designed to be delivered doesn’t quite work as planned. Test have shown that very little of the hormone actually makes it into the system, and that levels are very inconsistent from day to day with different users.
Results from Testosterone undecanoate are usually similar to those seen from the shorter esters of testosterone such as propionate or suspension. Because of this, estrogenic side effects are easily controllable and the drug is considered usable during all phases of preparation. This also makes the drug favorable for the drug tested athlete, because it can be removed from the system very quickly by discontinuing use. Users will often see noticeable gains in both size and strength, along with heightened libido and a greater sense of well being that is common with the injectable versions of testosterone. Testosterone undecanoate can be stacked with other drugs such as Deca or Trenbolone, and orals such as Winstrol, Dianabol, and Anavar etc. When running TU, users may want to add an anti-estrogen such as arimidex or aromasin to their cycle to prevent any possible estrogen related side effects that may occur. Also, users may want to add Proviron to their cycle in an effort to reduce SHBG binding and free up as much testosterone in the body as possible.
8-16 capsules per day. Testosterone undecanoate has a short half-life of 3-5 hours, and unlike most other orals, is completely ineffective beyond its half life, thus making a dosing schedule of at least three times a day necessary in order to keep some amount of the hormone present in the blood. It is recommended that the capsules be taken with food due to the fact that the lymphatic system by which the drug is delivered is activated by the secretion of stomach bile used for digesting food.
