    Nandrolone Phenylpropionate Ontario Pharma


    Nandrolone phenylpropionate is an injectable form of the anabolic steroid nandrolone. The properties of this are strikingly close to those of Deca-Durabolin®, which uses the slower acting drug Nandrolone Decanoate. The most important difference between these two preparations is the speed of release into the blood of Nandrolone. While Nandrolone Decanoate provides a release of Nandrolone from the area of injection lasting approximately 3 weeks, Nandrolone Phenylpropionate is active for only about a week. In clinical situations, Deca-Durabolin can be injected once every 2 or 3 weeks, while Durabolin® is usually administered every few days to once weekly. Otherwise, the two drugs are virtually interchangeable. Like Deca-Durabolin, Durabolin is valued by athletes and bodybuilders for its abilities to promote strength and lean muscle mass gains without significant estrogenic or androgenic side effects.

    Side effects

    Nandrolone has a low tendency to convert to Estrogen, estimated to be only about 20% of the case seen with testosterone. This is because while the liver can convert nandrolone to estradiol, in other more active sites of steroid aromatization, such as adipose tissue, Nandrolone is far less prone to this process. It is of note that Nandrolone has some activity as Progestin in the body. The side effects associated with progesterone are similar to those of estrogen, including negative feedback inhibition of testosterone production and enhanced rate of fat storage. Although classified as an anabolic steroid, androgenic side effects are still possible with this substance, especially at higher doses. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male-pattern hair loss.


    The usual dosage for physique- or performance-enhancing purposes is in the range of 200-400 mg per week, taken in cycles of 8 to 12 weeks in duration. Intake at this level is assumed to provide measurable gains in lean muscle mass and strength.
