Andriol is one of the few new steroids developed in recent years. Unlike most anabolic steroids introduced to the market in the 50s and 60s (and some of which have now disappeared), Andriol has only been around since the early 80s.

This is certainly the reason why this product holds a special place among steroids. Andriol is a revolutionary steroid, indeed, apart from methyltestosterone, it is the only effective oral testosterone preparation.

Testosterone taken by mouth is normally ineffective because it is absorbed through the portal vein and immediately neutralized by the liver. The substance in Andriol, on the other hand, testosterone undecanoate, is absorbed from the intestine through the lymphatic system, bypassing the liver, so the substance taken by mouth remains effective. The preparation does not affect the functioning of the liver.

Testosterone undecanoate is an ester of the fatty acid contained in the natural androgen, testosterone, and is largely transformed in the body into dihydrotestosterone, a metabolite of testosterone. This is the reason why Andriol changes its composition very little, so only a small amount of the substance can convert into estrogen, because dihydro-testosterone itself does not change its composition.

Andriol therefore does not cause feminization in its users, resulting in gynecomastia or fat overload.


This product is therefore particularly well appreciated by athletes who are not satisfied with the usual preparations based on injectable testosterone. Andriol is therefore a product that is well suited to the preparation phase preceding competitions.

The absence of modification of the components of Andriol also has the advantage of influencing the production of hormones made by the body only after a long period of administration and with high doses. Andriol has only a weak inhibitory action on the functioning of the hypotalamus by which the release of LHRH (Luteinizing Hormone Releasing Hormone) is hardly changed.

This is very important because (as we know) LHRH stimulates the pituitary gland which then releases gonadotropin, which allows the Leydig cells in the testicles to produce testosterone. Everything suggests that Andriol is the perfect steroid. However, it is not the case.


For athletes, Andriol has the disadvantage of only being effective in very high doses. Even taking 200mg per day, blood testosterone levels are not sufficient to assure bodybuilders proper muscle development and increased strength.

The product having an extremely short half-life, it is therefore essential to take it daily in a high dose. The body, in fact, very quickly eliminates testosterone undecanoate through the urinary tract.

The capsules are therefore only effective for a few hours, which is why you must take 6 to 7 per day, at a rate of 240 to 280 mg (minimum) per day, if you want to obtain the same results as with injection preparations. However, in the presence of such a dosage, the hormonal production is necessarily influenced and the preparation tends to be transformed more into estrogens. Such a dosage can also lead to an increase in water and sodium retention.This is a factor that athletes, especially competitive athletes, should consider.


The Andriol/Oxandrolone formula allows athletes with little experience with steroids to obtain an appreciable gain in strength and, most of the time, a satisfactory development of muscle mass. This formula is also interesting for athletes over the age of forty.

Those who are preparing for a competition and who dread regular injections can replace Testosterone Propionate with Andriol. Andriol is very quickly eliminated by the body, which makes it a product that can be administered before competitions involving doping controls.

It is a product, however, not recommended for women because the androgenic components – as is generally the case with testosterones – are strongly dosed in it. In some cases, the use of Andriol can be the cause of high blood pressure, water retention, acne, hyper sexual arousal and, in women, the famous phenomena of virilization.


Andriol has the advantage of being well supported by the body. For example, it can be used in combination with Deca-Durabolin as part of a long-term treatment and this product combination can be an alternative for health-conscious athletes to the well-known Dianabol/Deca-Durabolin mix.

Like Sustanon 250 and Testoviron Depot 250, proven injectable testosterones, Andriol should theoretically lead to a rapid and safe development of power and muscle mass as well as significant water retention. Alas, this is not the case.

Athletes who, when preparing for a competition, retain too much water and whose tissues remain smooth after taking Testosterone Depot Injection (but who despite everything do not want to give up testosterones) should not have estrogen-related problems, as long as they do not exceed the daily dose of 240 mg of Andriol, in addition they should be able to reduce their water retention. It is necessary to keep estrogen levels as low as possible during this phase, otherwise even the best diet would not work.

The use of Andriol is entirely indicated here and generally gives satisfactory results.
