Andriol was developed by the drug company Organon, and it was made available in the early 1980’s. The main objective of the drug was to provide an oral testosterone version that did not go through the liver. In addition, the idea was to create an anabolic-androgenic oral steroid that could be used for androgen replacement therapy and/or hypogonadism for men who had low testosterone. With the current success of topicals such as androgel, andriol has lost the little popularity it ever had.
How it works
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.
Testosterone 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.
Side effects are very low with andriol because it is a weak version of testosterone. Though, like all forms of testosterone, you can expect some aromatization into estrogen. Therefore, if you are prone to estrogenic sides, you still need to use an aromatase inhibitor (AI) with andriol. Although the conversion seems to be low, a small dose of aromasin, or arimidex can be used.
Restandol (Andriol) 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) Restandol (Andriol) has only been available since the early 1980’s. This fact probably explains why Restandol (Andriol) holds a special place among the steroids.
Restandol (Andriol) 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 and immediately deactivated by the liver.
The substance testosterone undecanoate contained in Restandol (Andriol), 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 Restandol (Andriol) 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 Restandol (Andriol) therefore do not experience feminization symptoms such as gynecomastia or increased body fat.
