Chemical structure of Testosterone Undecanoate

As previously mentioned, Andriol(Testosterone Undecanoate) is merely an esterified variant of Testosterone, whereby Testosterone has been affixed with the Undecanoate ester at the 17-beta hydroxyl group. It is vastly different from all other oral anabolic steroids because it does not contain methylation (C-17 alpha alkylation) on the 17th carbon, and therefore does not exhibit any of the negative effects on the liver that C-17 alpha alkylated compounds do. It also does not exhibit the same method of absorption and avoidance of the first pass of the liver that C-17 alpha alkylated oral compounds do. 

Instead, because of Andriol’s very long-chain fatty acid ester, it is extremely lipophilic and enters the body via the lymphatic system through the GI tract.

Dosage of Testosterone Undecanoate

Medically, Andriol dosages are prescribed in the range of 120-160 mg per day for the first 2 to 3 weeks. Following this initial period, prescription guidelines call for a reduction of Andriol dosage to a maintenance schedule of 40 - 120mg per day.

For performance and physique enhancement, the Andriol dosage must understandably be far greater. A minimum of 250mg per day is required (6 or 7 capsules) to see any measurable effect, and many individuals claim that the results at this range are on the low end. Commonly, Andriol is used at a dosage of 400-500 (10 - 14 capsules) per day. 

Advanced or experienced users may require even higher dosages than that.

Due to the lipophilic nature of Andriol's pharmacology, it is recommended that Andriol dosages be administered with the consumption of food / meals, ideally with a higher fat content in order to maximize its absorption in the body through the lymphatic system. When taken on an empty stomach, studies have demonstrated extremely low absorption and bioavailability of Andriol. Andriol dosages should also be split into two evenly spaced dosages (e.g. morning and evening) in order to maintain steady and stable blood serum levels of Testosterone.
