Testosterone Undecanoate (Andriol) profile

Testosterone undecanoate or testosterone undecylate androgel is an ester of testosterone. This hormone is used in androgen replacement therapy primarily for the treatment of male hypogonadism, and is currently under research for use as a male contraceptive. It is sold and distributed under the brand names Aveed, Andriol, Undestor, Nebido, Pantestone, Restandol, Cernos Depot, Nebido-R and Reandron 1000.

Andriol (testosterone undecanoate) is an orally-active version of the anabolic steroid testosterone developed by Organon. This version of testosterone is based in oil and is sealed in a capsule to be taken orally. According to the manufacturer, this method bypasses the liver and enters the body as a fat through the lymphatic system.

In theory this seems quite interesting, however, athletes find Organon’s claims about Andriol don’t hold up well. In doses of less than 240mg per day effects are generally non-existent. With higher doses, effects are small at best. This leads one to think most of the steroid is not making it to circulation.

Generally, steroid users experienced with any strong anabolics will be disappointed with Andriol’s results. Combined with other anabolics androgel it may lend some effectiveness but should be questioned.

Unlike other oral steroids, Andriol does not go through the liver, instead it goes through the lymphatic system. This allows the steroid to avoid being destructed by the liver, and enter the blood stream, intact. Interestingly, this would set it apart from the other oral steroids which are 17-aa or methylated.

Tell your doctor right away if you have any serious side effects, including: breast swelling/tenderness, mental/mood changes (such as depression, agitation, hostility), unusual snoring or difficulty breathing during sleep, swelling hands/ankles/feet, symptoms of liver problems (such as loss of appetite, persistent nausea/vomiting, severe stomach/abdominal pain, yellowing eyes/skin, dark urine), trouble urinating, too frequent/prolonged erections, fast/irregular heartbeat.

Andriol effects

Testosterone androgel is the male hormone responsible for gaining muscle, losing fat, gaining strength and other man-like features. Bodybuilders will utilize hormones such as testosterone as performance enhancing drugs during cycles. Usually, pure testosterone can serve as a safe and low side effect way to get a test base during a cycle.

Although it is considered a weak steroid, andriol will still have positive effects on recovery, workouts, and libido when used at higher dosages. Bodybuilders who do not want to inject, or use topicals due to allergies or convenience, can use oral andriol instead without fear of damaging their livers.

It is not recommended you run andriol alone, as it is too weak to see results. If you don’t stack it, you’ll see results comparable to using proviron alone.
