Nandrolone Phenylpropionate – NPP Steroid

Nandrolone Phenylpropionate or shortly called NPP is the first version of Nandrolone. This is a 19-nor steroid having less androgenic and more anabolic activity compared to base testosterone.

  • NPP comes only as an injection. There is no oral version of NPP (such as NPP tablets).

NPP was created many years ago for various medical purposes. It was used to treat breast cancer in women, osteoporosis, and many other health conditions. However, due to its amazing properties for physique and performance enhancement purposes NPP is popular in bodybuilding. It has powerful anabolic effects (higher than that of testosterone) and weaker effects (lower than testosterone).

As you can notice, the active substance is the same as in Nandrolone Decanoate (Deca). This is the second version of Nandrolone, which ended up more popular than NPP because of the longer ester. This means Deca should be used less frequently than NPP.

That’s why Deca became the favored version in medical settings. It soon became more popular in the bodybuilding world too. They both offer the same active substance but NPP should be used more frequently.

Nevertheless, NPP still has its own advantages over Deca. So, Deca Durabolin (Nandrolone Decanoate) may be more popular than Durabolin (Nandrolone Phenylpropionate). But many people don’t even know the advantages of NPP.

For example, there’s no need to run a kickstarter with NPP as you would need with Deca cycle. That’s because Deca needs a long time to start offering effects while NPP kicks in much faster. At the same time, if you get side effects and stop using the product, with Deca those effects would linger for a long time.

Also, the side effects are much easier to control with NPP steroid. You can adjust dosage according to how you feel it working. Also, a lot of people swear that they get less water retention and less libido loss with NPP than Deca. So you get a leaner bulk.

In the end, both Nandrolone versions are amazing with their own advantages and disadvantages. Which one to choose highly depends on your own needs, tolerance, goals, etc.
