    Testosterone undecanoate or testosterone undecylate 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.

    Bodybuilding

    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.

    Dosages and Half-Life

    Hormone replacement therapy (HRT) doctors will typically kickstart treatment with 120-160mg of andriol per day, split dose, and then stay at 120mg per day thereafter. For bodybuilders and competitive athletes, this dosage will not do very much, and they tend to dose up to 480mg per day. Though, personally I found these doses to be a bit excessive. If you combine it with other orals, 200-250mgs per day can work fine. It is recommended to take andriol before a meal.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.

    The half-life of andriol is fairly short, you’ll need twice a day dosage. The suggested split is in AM, before breakfast, and in PM, before dinner.

    Side effects

    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.
