Testosterone undecanoate is best known by its common trade name of Andriol . It was developed to be a safer , oral testosterone alternative to the injectible testosterone that most athletes are familiar with . This brings some advantages and also some disadvantages for users . On the one hand , Andriol is easy to use because it is ingested as a pill and there is no need for syringes . However , muscle gains from using Andriol alone are very slight . Also , because the drug is only active in the body for several hours , users must take several pills a day to feel the effects of the drug . 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 .

1. Testosterone undecanoate is an ester of testosterone which is used for the treatment in males to treat primary hypogonadism ( congenital or acquired ) - testicular failure due to cryptorchidism , bilateral torsion , orchitis, vanishing testis syndrome , or orchidectomy and is currently under research for use as a male contraceptive .
2. Testosterone 500 USP injection provides Testosterone undecanoate , a derivative of the principal endogenous androgen testosterone , for intramuscular administration . The esterification of the 17 - beta - hydroxyl group increases the duration of the action of testosterone . Testosterone esters in oil injected intramuscularly are absorbed slowly from the lipid phase , so Testosterone 500 can be administered at intervals of 10 - 14 weeks .
3. Testosterone 500 contains Testosterone undecanoate in a 10ml solution for injection ( 500mg Testosterone undecanoate / ml ) .
4. Testosterone 500 is a clear , yellowish oily solution for intramuscular injection .
