Information: Nandrolone Phenylpropionate is a 19-nortestostrone (19-nor) androgenic anabolic steroid. The 19-nor classification refers to a structural change in the hormone testosterone in that the carbon atom was removed at the 19th position. This simple structural change gives us nandrolone, and adding the short ester of phnylpropionate we have nandrolone phnylpropionate.

Since nuclear power plant and deca share the same active substance, nandrolone, their history is very closely linked. Not many people know that nandrolone as such was developed in 1957, and the most popular version of this steroid was actually the one with phenylpropionate ester attached to it.

Nandrolone phenylpropionate has two positive moments over Deca: 1st is a shorter ester reduces the risk of side effects. 2sd is that in case of side effects or poor tolerance, the cycle can be stopped and all reactions will stop.

Nandrolone Phnylpropionate Profile

Androgen index – 37-30
Anabolic Index – 125-150
Estrogne Level – Low
Progestin activity – Moderate
Liver Toxicity – Low


Nandrolone Phenylpropionate (aka Durabolin) has a good anabolic effect which leads to steady and consistent muscle growth.This is accompanied by a moderate androgenic effect, thus accelerating regeneration and maintaining mass even during the diet. Additionally, it is associated with much lower water retention than Nandrolone Decanoate (Deca-Durabolin), making it more suitable for cutting (pre-competition) cycles, while Nandrolone Decanoate is more suitable for mass and strength.

  • Increases protein synthesis
  • Improves absorption of amino acids from the small intestine
  • Increases prolactin
  • Increases your red blood cell count
  • Boosts the immune system
  • Therapeutic benefits for the joints
  • Improves bone density
  • Increases collagen synthesis

Many people think that there is a big difference between Deca and Nandrolone Phenylpropionate, but the active substance is the same Nandrolone, so the only difference is the speed of action.

Side effects

There are several possible side effects of using Nandrolone Phenylpropionate, but it is also one of the most user-friendly side effects. The key to managing and avoiding side effects is understanding how they happen and using the hormone correctly. For most men, serious side effects should be completely avoidable.

The reason for most side effects is high prolactin levels.

high doses, possibility of water retention and high blood pressure caused by severe water retention. These side effects can be avoided by using an Aromatase Inhibitor (AI) such as Anastrozole (Arimidex).

Hair loss in men predisposed to male pattern baldness is possible, as is acne in susceptible men.

Nandrolone reduces the level of endogenous gonadotropin and testosterone production. And this is the main reason for the long recovery after the cycle.

After cycle therapy

To reduce the level of prolactin, it is strongly recommended to use cabergoline (Dostinex) or bromocriptine.

Post cycle therapy is recommended and begins 12 to 16 days after the last injection.

Post cycle therapy with Nolvadex and Clomid is beneficial for restoring the production of natural hormone levels, including testosterone levels, as quickly and effectively as possible.

This will help stimulate natural testosterone production and increase the chances of a successful recovery. The PCT will not complete the recovery, it will still take several months after the PCT, but it will give you a better start.

The Nandrolone Phnylpropionate cycle is recommended for use with testosterone, to avoid the progestin effect and the consequences of low testosterone (low libido, weak erection).
