Nandrolone Phenylpropionate (NPP) 10ml – 100mg/ml. NPP is a well known drug in bodybuilding for Canadians and is usually the preferred option for Canadian bodybuilders over other Nandrolones such as Deca Durabolin.



NPP is also used in order to treat an array of medical conditions. Patients with HIV and cancer may benefit from injecting it, as may patients with fatigue and muscle-wasting illnesses. As well, those who are anemic may benefit. Other examples of conditions which may be treated with Nandrolone Phenylpropioniate include breast cancer, anemia, pituitary dwarfism, serious burns, ulcers, mental development problems (in children) and osteoporosis.


  • Estrogenic: Since this steroid is estrogenic, it may trigger development of male breast tissue, bloating and higher blood pressure.To avoid these side effects, men may wish to use Aromatase inhibitors.
  • Androgenic: The risk of androgenic side effects is lower, but not non-existent. Examples of androgenic side effects include acne and hair loss (male pattern baldness). In women, virilization is a possibility. If women notice virilization problems, they should stop taking NPP immediately. For example, a women may find that her clitoris grows larger, that her voice deepens and so on. It’s important to stop injection of this steroid immediately if these problems begin to manifest.
  • Female Side Effects: When a woman stops using NPP right away, the chances of the virilization symptoms being reversed will be great. If she persists in using the steroid, despite symptoms of virilization, it’s possible that the symptoms won’t reverse.
  • Cholesterol: This steroid may negatively impact good cholesterol levels.
  • Testosterone Inhibition: This hormone will inhibit the production of natural testosterone. Men who use the steroid should do so while using exogenous testosterone.


For best results and to minimize the risk of side effects, fifty to one hundred milligrams (50-100mg) of NPP per day is recommended. This injectable steroid can be used daily or three times per week. Advanced level bodybuilders can use larger doses, such as 400-800mg per week.
