Nandrolone Phenylpropionate (NPP) Powder Overview.

Nandrolone phenylpropionate (powder form) is commonly NPP for short. Nandrolone phenylpropionate (NPP) is a short ester nandrolone which means it has to be injected every other day or every 3 days at the most to keep the level. NPP is usually doesd at 300mg per week. A combination of nandrolone phenylpropionate and nandrolne decanoate should be a better choice.

Must-Know For Nandrolone Phenylpropionate Powder.

Once your nandrolone phenylpropionate powder is received, please store it in a sealed container and put it in refrigerator at around 0~5°C. The shelf life is 4 years if stored properly. And kept away from unauthorized use, pets, sunlight, moisture, and children.

  • The melting point of nandrolone phenylpropionate powder is just around 94~95°C. Brewing temperature can be 94~95°C.
  • Nandrolone phenylpropionate has an active life of 1-2 days, it needs to be injected every other day or every 3 days.
  • The highest strength we made for nandrolone phenylpropionate oil is 150mg/ml with powder and necessary solvents.

More About Nandrolone Phenylpropionate (Powder).

As we mentioned nandrolone phenylpropionate (NPP), I think we have to compare it with nandrolone decanoate (DECA). To understand the other advantages of using Nandrolone Phenylpropionate we must then understand half lives and what they mean.

Nandrolone phenylpropionate has the shorter ester while decanoate 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.

Nandrolone phenylpropionate (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. Nandrolone decanoate (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. A common complaint is that Nandrolone decanoate (DECA) requires either a long cycle or it has to be stacked with fast-acting injectables or orals. 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.

Nandrolone decanoate (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.

In my opinion, 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. 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. But now the highest NPP mg/ml ratio we made is 150mg/ml.

How to use this Anabolic Steroid calculator

To calculate 40ml of oil at 100mg/ml with 2% ba and 18%
(1) In the oil field enter 40
(2) In the dosage field enter 100
(3) Unless you know for sure, usually leave powder weight alone.
(4)  BA Concentration is set at  2%, if you wanted less, then change it accordingly
(5) BB concentration is set at  18%, if you wanted less, then change it accordingly
(6) You should now have the results :
Oil = 29mls
Powder = 4 grams
BA = 0.80ml's
BB = 7.20mls

Notes: BB is not always needed in certain experiments BB = benzyl benzoate BA = benzyl alcohol
Enter Amount Required
Total oil in mL  40ml = 40
Dosage in mg/mL   250mg/ml = 250
Powder Weight  normally .75 to .94
BA percent  2% = 0.02
BB percent   20% = 0.20
Results - Amounts Needed
GSO / Carrier Oil - - ml's
Powder - - grams
BA - - ml's
BB - - ml's
