Testosterone Undecanoate

Andriol is a unique oral testosterone product, developed by the international drug firm Organon. One of the more recently developed anabolic steroids, Andriol first became available in the early 1980's. This compound contains 40 mg of testosterone undecanoate, based in oil (oleic acid) and sealed inside a capsule. Subtracting the ester weight, this equates to a dosage of approximately 25mg of raw testosterone per cap. The design of this steroid is quite different from that of most oral steroids. Drugs administered orally generally enter the blood stream through the liver. When a steroid compound is given this way without some form of structural protection, it will be quickly broken down during the "first pass". This process leaves very little steroid intact, basically deactivating the drug. Adding a methyl group (c-17 AA) to the structure is one way to protect it from this process, however stress is also placed on the liver as a result. In some instances this stress can lead to actual damage to liver tissues, so the designers of this steroid sought another way to protect the testosterone molecule. With Andriol, this was accomplished by making a form of testosterone that would be absorbed through the lymphatic system. This is due to its high fat solubility brought about by the ester, and its suspension in oil. Having the compound absorbed this way was thought to be very advantageous, as it allows the steroid to bypass the destructive first-pass through liver. This should permit the compound to enter the blood stream intact, without the need for a harsh chemical alteration. The ester breaks off once it is in circulation of course, yielding free active Pharmacokinetics of Orai Testosterone testosterone. In design this steroid appears to be undecanoate that of a completely liver safe and orally active form of testosterone.

Applications:

 

Testosterone Undecanoate is a fatty acid ester of the natural androgen, Testosterone, and in the body is for the most part transformed into Dihydrotestosterone, a metabolite of testosterone. For this reason Andriol aromatizes only minimally, meaning that only a very small part of the substance can be converted into Estrogen, since the Dihydrotestosterone does not aromatize. The users of Andriol therefore do not experience feminization symptoms such as gynecomastia or increased body fat.

 

 

Testosterone undecanoate or testosterone undecylate is an ester of testosterone which is used for the treatment of male hypogonadism, and is currently under research for use as a male contraceptive, testosterone undecanoate is sold and distributed under the brand names Andriol, understor, nebido, pantestone, restandol.

Andriol is a version of the anabolic steroid testosterone undecanoatedeveloped by the pharmaceutical company organon, testosterone is said to enter the body as a fat through the lymphatic system, experience from user indicates that in dose of less than 240mg per day, effects are negligible, except at every onset of use, while even in higher dose , effects are still minimal , testosterone undecanoate is therefor thought that most of the steroid is somehow not making it into the blood stream.
