>> general information

Andriol is a unique oral testosterone product, it is one of the more recently developed anabolic steroids. This compound can be made as based in oil (oleic acid) and sealed inside a capsule, contains 40 mg of testosterone undecylenate per 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 Undecylenate that of a completely liver safe and orally active form of testosterone.


>> testosterone undecylenate is a mild oral steroid

Most athletes today consider Andriol a very poor buy. I know other references do find use for this drug, which is defendable because some amount of steroid clearly does enter the blood stream in tact. Technically it is still an oral testosterone, and definitely does not carry the same liver-toxicity risks associated with most steroids designed for this type of administration, so all is not Post. Those specifically looking for a mild oral at times do purchase this product, and occasionally are even satisfied with their results. But for most its high price and required high daily dosages usually causes them to avoided it when crossing it on the black market. Besides, if we want a mild steroid the last thing we really should shop for is a testosterone.
