In this section we’re going to focus on Getting The Most From Nandrolone and Phenylpropionate  so that you are able to understand what to expect using nandrolone decanoate.

We’ll break down the basic effects of nandrolone and how they might impact the three primary scenarios they are likely to be implemented into before expanding on the unique benefits of each ester / ester blend available.

By the end of this section, you should be under no illusion in regards to what to expect when using nandrolone and how it can positively impact your chosen sport and your life.

Taking Nandrolone In The Bulking Offseason

Getting The Most From Nandrolone and Phenylpropionate

 Using nandrolone during a bulking phase is extremely commonplace and is primarily where this steroid gets integrated.

When you think about it though (having assessed the chemical structure of this compound previously) deca shouldn’t really be the one of the best choices available for developing mass – on paper, it has a fairly weak anabolic rating when compared to other steroids and it can’t really boast the kind of “extreme” mass that compounds like anadrol are capable of delivering due to estrogen related water retention. Why is it then that nandrolone is and always has been so widely used during a bulking phase?

We’ll first consider the facts (in relation to bulking), which are:

  • Nandrolone has been available for longer than many other steroids, therefore it’s guaranteed to be a “go-to” choice owing to its trusted and well-established history
  • Nandrolone is excellent for retaining nitrogen in the muscle cells
  • Nandrolone can enhance the anabolic atmosphere of the body and lead to other steroids being more effective as a result when used as part of a larger cycle
  • Nandrolone is excellent for enhanced joint recovery
  • Nandrolone is slightly more anabolic than testosterone


Getting The Most From Nandrolone and Phenylpropionate . All of the above positive benefits relate to a bulking phase in some way; they would all be useful when integrated into a cycle of this type.

We’ll start with the first benefit and state that by default, the lifespan of this steroid simply means that it has been used by more people, and as a result has somewhat of an unfair advantage in regards to being deemed as a useful steroid for bulking with (at one point, it was one of the only options a bodybuilder would have available when trying to gain muscle – any benefit at this point would have been better than none at all.) This is actually somewhat of a backhanded compliment; we’re suggesting that its decades old reputation may override its usefulness when being considered for utilisation within a bulk. Or at least, that could be the case if nandrolone didn’t actually prove to be so useful when implemented into a bulk by the right person.

We’ll get onto the latter part of that last statement shortly – for now though, be open to the fact that nandrolone shouldn’t necessarily be viewed as a “mighty” bulking agent purely by default due to its reputation. To make it work effectively, you’ll have to delve into the compound’s structure and work with it intricately as we’ll soon explain.



 Nandrolone Phenyl Propionate (NPP). A Longer Ester Propionate Cycle

Nandrolone Phenyl Propionate (NPP) Explained and why Its a Much Better Steroid Choice Than Long Estered Nandrolone Decanoate.

Nandrolone Phenylpropionate
NPP Steroid

NPP was never really all that popular simply because of availability issues. Many of the pharmacy grade NPP products range between 25mg-50mg/ml and are extremely expensive. Naturally, this limited its use among the bodybuilding crowd. Mexico and the underground did not bother producing it.

The recent increase in popularity of NPP can be attributed to the introduction of BM’s Dubol-100; the first affordable pharmacy grade 100mg/ml NPP. Eventually, more and more Underground Labs started producing the forgotten drug.

PhenylProp vs Decanoate.

Here is some interesting information:

“Let’s calculate the amount accumulated in the body after 6 weeks of 500mg/deca. Let’s say you inject it once a week and we’ll give it a 1.5-week half-life. Note that injection frequency makes a huge difference in blood concentration stability but no difference in amount of esterified in the system
E (greek letter “sigma”) 500*e^(ln(1/2)n/1.5) from n=0 to n=6. So after 6 weeks, about 1300mg of esterified nandrolone remain in the body.
Now lets see how long, after the initial injection, it takes to reduce to a small enough amount that permits recovery.

1300*e^(ln(1/2)n/1.5) After 3 weeks, 325 mg of esterified remain
after 6 weeks, 81 mg of esterified remain.
After 8 weeks, 32mg of esterified remain.”

Nandrolone Decanoate is a long acting depot; it takes quite a while for it to “kick in” and clear out of the system. Depending on how much is used; it will take at least 4-6 weeks after the last shot for Deca to clear out. It also takes about 4 weeks for active blood levels to stabilize. This can easily add up to 8-10 weeks of “dead time” i.e. periods of time when blood levels are not consistent.

These numbers apply to reasonable use of Nandrolone Decanoate; between 200-400mg a week. The more you use, the worst it gets. So a 10-week cycle of Deca can easily end up been a 16-week cycle when you account for clearance time (active blood levels). The first 4 weeks are also somewhat of a waste of time.

So that 10-week cycle ends up been 16 weeks; 6 weeks of optimal blood levels and 10 weeks of dead time. Not a very effective way to cycle.
With NPP, you can bypass all that dead time.

19-Nortestosterone based drugs are known to shutdown HPTA very easily – think Trenbolone. Most bodybuilders will use Tren for around 6 weeks at the beginning of a cycle. NPP should be used in a similar manner.

Here’s an example of a balanced cycle consisting of NPP
W1-6: Dianabol
W1-6: Nandrolone Phenyl Propionate
W1-8: Testosterone Propionate
W1-8: IGF-1 Lr3

It is a good idea to run Test 2 weeks past the NPP, however; NPP can be used as a stand-alone.

Earlier, I compared NPP to Tren. They are similar in some ways but Trenbolone is much more androgenic and stronger in general.

NPP shares some of the same sides associated with Deca (they are after all the same base compound). It should be noted that most of the sides that come with Deca are a result of its long ester. Decanoate ester is very hard to control and Nandrolone side effects are not easily countered like Testosterone related sides (Tamoxifen, Anastrozole, finasteride…)
Overall, Nandrolone is a milder compound than Testosterone and is better mg for mg (but that’s a matter of opinion)

Nandrolone PhenylProp should be injected at least every 3 days.

A typical dose is 350mg-700mg a week for 5-8 weeks.

It stacks very well with Winstrol, Dbol, Test, EQ, Anavar

It does not stack well with Tren and especially Anadrol

Here are some good cycle suggestions:

Fast Acting Classic Test/Deca/Dbol cycle:

W1-8: IGF-1 Lr3: 50mcg ED
W1-6: Dbol 30mg ED
W1-6: NPP 150mg EOD
W1-8: Test Prop 150mg EOD

Highly Anabolic cycles
W1-8: IGF-1 Lr3: 60mcg ED
W1-6: NPP: 200mg E3D
W1-8: Anavar: 30mg ED
W1-6: NPP: 200mg E3D
W1-8: Winny: 50mg ED

A good First cycle:
W1-6: NPP: 150mg E3D
W1-4: Dbol: 25mg ED
(W5-8: Anavar: 30mg ED – optional)
W1-8: IGF-1 Lr3: 30mcg ED

NPP in a typical cycle
W1-10: EQ 400mg a week
W1-9: Test Cyp 600mg a week
W1-8: NPP 200mg E3D
W10-13: Test Prop 150mg EOD
W1-13: IGF-1 Lr3: 50mcg ED

In Conclusion:

Nandrolone got a very bad rap with many bodybuilders; there is no reason to use Nandrolone Decanoate if NPP available aside from year-round juicer using it for joint pain. Nandrolone is a tremendous bodybuilding drug that can take your physique to a whole different level but many people shy away from it because of what they have heard or experienced with Deca.
