NPP by Pharma Tech Labs is Deca Durabolin (Nandrolone Decanoate) attached to a faster ester. It has the nickname fast-acting Deca. Much like Deca, this is a 19-nor Steroid, which basically means that a testosterone hormone has the carbon atom eliminated in the 19th position.
This compound seems to behave very similar to Deca, but it has the benefit of delivering faster results and with less water retention. Many users do not like Deca, because it tends to cause massive water retention. NPP provides all the usual benefits of Deca, such as an increase in lean muscle mass, strength, and joint lubrication without some of the unwanted side effects of Deca. NPP also delivers faster results compared to Deca, because the hormone is attached to a faster-acting ester compared to regular Deca Durabolin.
NPP can be used both during a cutting phase and a bulking phase because it is very anabolic, mildly androgenic, and it does not cause too much water retention. Most users tend to stack with a compound with Testosterone Propionate and an oral Anabolic such as Dianabol or Anadrol for a fast bulking phase. Alternatively, it can also be used with Testosterone Enanthate during a heavy bulking phase, but keep in mind that due to the ester, NPP should be administered ideally every other day or every 3 days.
