To understand the other advantages of using Nandrolone Phenylpropionate we must then understand half lives and what they mean. To put it in simple terms NPP will be quicker to build up to peak levels in the body and will be quicker once you stop injecting to filter out of the body. Deca meanwhile because of the extremely long ester will take much longer to build up and worst of all takes longer to trickle out of the body, this will cause a much longer recovery for those of you who cycle. So deca is a poor choice if you like to keep cycles under 10 weeks and want to run multiple cycles per year, and NPP is a realistic option. Deca Durabolin will take about 6 weeks to clear out of your body and is also detectable for up to 18 months! NPP meanwhile will clear out much faster, I would guestimate about 2-3 weeks at the most where the body can begin recovery. This 3-4 week difference is major when dealing with nandrolones.
Another slight disadvantage with NPP is some users will say the injections can be more painful then the much smoother deca injection. However I can assure you it is nothing as bad as prop.
