Nandrolone Phenylpropionate (NPP) is the lesser known and less popular phenylpropionate ester version of nandrolone. First off its important to understand the difference between what we know as ‘deca’ and what we know as “NPP”. To put it in simple terms the difference is simply the ester. NPP has the shorter ester while deca durabolin version of nandrolone has the longer ‘deca’ ester. Many lifters have no clue they can use the compound they love so much in a shorter ester. The only disadvantage would be the amount of injections, the shorter ester would have to be injected every other day or every 3 days at the most, while the long ‘deca’ ester can be injected once or twice a week. However the advantages are there which I will discuss as we go along.
The main reason Nandrolone Phenylpropionate never became as popular as the deca ester is because of the availability and the small amount of amount per ml in the pharm grade version. Deca Durabolin meanwhile came in 200mg per ml so really guys found it much easier to inject 200mg twice a week using just 1ml per injection. Now with the growth of underground labs this issue has disappeared and now you can get NPP in all kinds of mg/ml ratios.
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.
nandrolone phenylpropionate genesisNow that we understand the difference between the two nandrolones lets take a look at the compound as a whole. First off, nandrolone is used to treat anemia so logic says it will be very good at raising RBC count which helps delivery of oxygen to muscles.. Its not a tremendous amount but it does the job. Also there is aromatization, so an AI is recommended of course. Nandrolone will aromatize about half as much as testosterone so you can see how deca got so popular with the old school crowd. Since they didn’t have AI’s back then they would use deca over testosterone or dbol (dianabol) to lessen their water weight. Many older lifters at your gym still juice today and have no clue what an AI even means, just ask them, and ask them their favorite steroid and they will likely say deca. Well that’s the reason!
NPP is commonly dosed between 300-1,000 mg per week for a period of 8-16 weeks in length. If one is using NPP solely for the alleviation of joint discomfort, a dose of 200-300 mg per week will usually suffice.
Sample Bulking Cycle
Testosterone Enanthate 500 mg/week 1-12weeks
Nandrolone Phenylpropionate 500 mg/week 1-12weeks
Dianabol 25 mg/day 1-6weeks
GHRP-6 300 mcg after workouts 1-12weeks
Nandrolone Phenylpropionate, also known as “NPP” is very similar to the very popular steroid “Deca” which is Nandrolone with a longer ester (Decanoate). Nandrolone Phenylpropionate is, therefore, a shorter acting “Deca” for all practical intents and purposes. Anecdotally, it seems to produce less water retention than its longer acting cousin, and this would be very consistent with injectable testosterones, where we find that shorter esters provide much less water retention.
