Nandrolone phenylpropionate has strong anabolic effects and relatively mild androgenic effects, this feature makes it good choice for those prone to androgenic side-effects. Nandrolone seems to have beneficial influence on connective tissue (joints) through its anti-inflammatory effects and increased collagen synthesis. Interestingly, nandrolone phenylpropionate seems to significantly increase the number of androgenic receptors.

One of the most beneficial effects of nandrolone is that it helps to shed the subcutaneous fat tissue. This action is more pronounced with higher doses.
Probably the main difference between Durabolin and Deca Durabolin is that Durabolin doesn’t cause water retention, or at least in much smaller scale.
