Active: Testosterone Undecanoate. Androxon is one of the few new steroids developed during the last few years. Unlike most anabolic steroids which were found on the market during the 1950’s and 1960’s (and which in part, have disappeared). Test Undecanoate has only been available since the early 1 980’s. This fact probably explains why Androxon holds a special place among the steroids. Test Undecanoate is a revolutionary steroid because besides methyltestosterone, it is the only effective oral testosterone compound. Testosterone itself, if taken orally, is ineffective since it is reabsorbed through the portal vein (1) and immediately deactivated by the liver. The substance testosterone undecanoate contained in Androxon, however, is reabsorbed from the intestine through the lymphatic system, thus bypassing the liver and becoming effective. The liver function is not affected by this. 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 Androxon 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 Test Undecanoate therefore do not experience feminization symptoms such as gynecomastia or increased body fat. This makes it a welcome alternative for athletes who have problems with the common injectable testosterone compounds. Due to this, Androxon is also suitable for pre-competition workouts. An additional advantage of Androxon’s non-aromatizing quality consists of the fact that the body’s own hormone production is only affected after a long—term administration of very high dosages. Androxon has only a low inhibitive effect on the hypothalamus so that the release of LHRH (luteinizing hormone releasing hormone) is rarely inﬂuenced. This is very important since—as we know LH-RH stimulates the hypophysis to release gonadotropine which causes the Ledig’s cells in the testes to produce testosterone. Consequently, Test Undecanoate should be the perfect steroid; however, this is not the case.
The disadvantage of Test Undecanoate is that it only becomes effective if taken in high doses. Even if a dose of 200 mg of Androxon/day is taken, the testosterone level in the blood is still too low for a bodybuilder to gain strength and muscle growth. The need for such a high daily dosage can be explained by its extremely short half—life time since the substance testosterone undecanoate is excreted very quickly by the body through the urine. The capsules, therefore, are effective for only a few hours so that 6—7 capsules, that is 240-280 mg (minimum), must be taken daily to achieve good results comparable to those of injectable compounds. This, however, puts the athlete in a dosage range which begins to inﬂuence the hormone production and the compound now more readily converts into estrogen. Such a dose can also manifest itself in a higher retention of sodium and water. This is one factor which competing athletes must consider.
The capsules should be taken three times daily (approximately every 8 hours) after meals so that the substance can be properly reabsorbed. However, even this high dosage does not guarantee satisfactory results. Those of you who believe that you need even higher doses should then consider that it might be more sensible to switch to the injectable testosterone. Androxon is often combined with Oxandrolone since oxandrolone also does not suppress the production of testosterone and, in addition, does not aromatize. The Androxon/Oxandrolone stack gives athletes who do not yet have much experience with steroids a fairly large strength increase and also often substantial muscle growth.
For athletes over forty this combination is also of interest. Those working out for competitions and wanting to avoid injections on a regular basis can substitute Testosterone propionate with Androxon. Since Androxon is quickly eliminated by the body it should also be considered for use before competitions requiring doping tests.
Women should avoid Test Undecanoate since the androgenic component, common with testosterone, is also strongly developed in this compound. Test Undecanoate intake can occasionally lead to high blood pressure, retention of fluids, acne, sexual overstimulation, and, in women, the well-known virilization symptoms.
In recent years testosterone undecanoate has been used in hormone replacement therapy for men with low testosterone levels. In this version, known as Nibedo, a single 4ml injection is used every 3 months. It is extremely effective in this regard. Due to the cost of the oral versions, Androxon is rarely available on the black market.
