The anabolic steroid nandrolone is most often referred to as Deca Durabolin, the trade name for its decanoate ester. However, the phenylpropionate ester, known as nandrolone phenylpropionate (a.k.a. "NPP"), is also very popular. In fact, some bodybuilders like the NPP steroid far more than the deca steroid because it acts extremely fast and clears out of your system quicker. Nandrolone, in general, is a great drug because it's highly anabolic and only aromatizes at 20% the rate of testosterone. So if you're interested in using NPP to attain fast muscle gains and cut fat, keep reading as we discuss 31 critical tips that you should know about this drug.<br />
<br />
1. You'll pack on Massive Amounts of Lean Muscle with NPP<br />
<br />
Few steroids can help you pack on lean muscle and boost your strength better than nandrolone phenylpropionate (1). It's not uncommon to see bodybuilders on forums boasting of up to 20 to 30-pound gains on a 10 to 12-week cycle. Research backs these claims up since NPP is commonly used to help muscle-wasting patients regain what they've lost (2) (3). What's more is that this drug helps you heal up much faster from brutal workouts (4). So if you're looking for an anabolic steroid that can dramatically transform your physique, then you'll definitely want to consider NPP.<br />
<br />
2. NPP will Boost Nitrogen Retention in Your Muscles<br />
<br />
As you may know, nitrogen is key to gaining lean muscle because muscle cells assimilate extra protein when they have a positive nitrogen balance. And this brings us to yet another benefit of nandrolone phenylpropionate since it helps your muscles retain more nitrogen (5). But the key is that you must keep your diet and protein intake strong if you're going to benefit from this nitrogen-boosting effect. So even if you're cutting, don't just rely on wheatgrass and hemp milk to feed your muscles for rapid growth.<br />
<br />
3. You'll have Higher IGF-1 Levels thanks to NPP<br />
<br />
You should see a significant rise in insulin-like-growth factor (IGF-1) when on nandrolone phenylpropionate. Research backs this up by showing that nandrolone increases IGF-1 mRNA expression levels in animals (6). And this is important because IGF-1 is a hormone that's key to packing on more lean muscle. Combining this with the nitrogen-boosting effect of NPP, you can really see how this drug has such a strong effect on muscle growth.<br />
<br />
4. Nandrolone Phenylpropionate helps provide Joint Relief<br />
<br />
The combination of lifting heavy weights and intense cardio on a consistent basis is not exactly easy on your joints. So it's not uncommon for bodybuilders to complain about joint pain after they've been training for a while. And this is where NPP can be of great benefit since it aids in collagen synthesis. One study showed that, even when dosed at just 50mg every three weeks, nandrolone boosted type III collagen synthesis (7). Anecdotal evidence backs up the research because many bodybuilders post on forums about the joint relief that nandrolone provides.<br />
<br />
5. Your Appetite will be out of Control<br />
<br />
If you're looking to pack on some serious lean muscle, then you'll find that NPP is an excellent drug for this! Nandrolone has a very powerful appetite-stimulating effect that should have you craving just about anything you can get your hands on. Assuming you have a difficult time stuffing calories down on cycle, nandrolone phenylpropionate will help you immensely. And this is a big reason some athletes report gaining up to 30 pounds or more during an anabolic steroid cycle.<br />
<br />
6. NPP is a Versatile Drug that can help you Bulk or Cut<br />
<br />
It might seem contradictory to follow the last point up with this, but it's worth mentioning that nandrolone is a versatile drug that can be used for both cutting and bulking cycles. The latter is most popular; however, NPP can certainly be a great aid to anybody who's trying to shed fat and get ripped. The key thing, though, will be keeping yourself out of the fridge late at night when you get hungry. But as long as you eat clean and do a decent job of staying away from Wendy's and McDonald's, you should get good cutting results from this drug.<br />
<br />
7. This Drug has many Medical Uses<br />
<br />
Most anabolic steroids can trace their origins back to therapeutic uses. Nandrolone phenylpropionate is no different in this regard because research has shown that it has many potential benefits. For starters, it can treat osteoporosis (8) and improve bone mineral density (9). NPP also raises red blood cell counts and has been used to treat anemia (10); this benefit helps deliver more oxygen to muscles, which boosts muscular endurance in athletes. And nandrolone phenylpropionate is also extremely useful in helping HIV patients gain back weight.<br />
<br />
<br />
8. You'll be More Dominant in Competitive Situations<br />
<br />
Many guys feel more powerful and better overall when they're on anabolic steroids cycles. And nandrolone phenylpropionate takes this a step further by actually helping one excel in a competitive situation. Research backs this up by revealing that mice on nandrolone were more dominant than placebo subjects (11). So if you're looking to crush the competition in any situation, then NPP is a good drug to take.<br />
<br />
NPP vs. Deca<br />
<br />
9. NPP causes Muscle Gain Far Quicker than Deca<br />
<br />
As mentioned in the introduction, the NPP steroid begins producing results much faster than Deca Durabolin (a.k.a. nandrolone decanoate). But exactly how much faster? Many athletes who take this drug can see results as quickly as 1-2 weeks; compare this to deca, where you're looking at a minimum of 4-5 weeks before you start experiencing significant muscle gains. So if you're looking for lean muscle growth sooner rather than later, NPP is definitely your steroid!<br />
<br />
10. You can also expect NPP to clear your System Faster<br />
<br />
Another advantage that nandrolone phenylpropionate has over deca is that it doesn't stay in your system as long. Given that it's faster acting, NPP metabolites clear your body within 10-12 months. Contrast this to the deca steroid, which can turn up on a drug test 18 months after your last injection. Neither drug is perfect for an athlete who's bulking in the offseason and fears a future drug test. However, NPP will at least be completely gone from your body several months sooner.<br />
<br />
11. Nandrolone Phenylpropionate also requires More Frequent Injections<br />
<br />
So if NPP provides faster results and exits your system faster, why aren't more people choosing it over deca? There are a few reasons why, but the biggest is the fact that it must be injected more frequently. NPP's half-life is only 2.5 days while deca has a much longer half-life of 6 days (12). This means that, with the phenylpropionate ester, more frequent injections must be administered to keep the drug running consistently strong in your bloodstream. The absolute minimum that you want to pin NPP is 3 days while most bodybuilders inject it every 1-2 days.<br />
<br />
12. The NPP Steroid used to come in Small Quantities<br />
<br />
Another reason for why NPP isn't as popular as deca today has to do with its history. Going further, nandrolone phenylpropionate wasn't as prevalent in the past, and its mg/ml ratios were really small compared to deca. So most guys just preferred the convenience of getting 200mg of deca from a 1ml syringe. This has largely changed thanks to online steroid pharmacies, which offer NPP in bigger mg/ml ratios; but older bodybuilders still use the deca steroid because they're used to it.<br />
<br />
How to use NPP?<br />
<br />
13. Here are Typical NPP Dosages<br />
<br />
Like any anabolic steroid, the amount of nandrolone phenylpropionate that you run largely depends on your experience, muscle-building goals and how well you handle side effects. But generally speaking, beginners usually dose NPP at 300-400mg per week while experienced users may take anywhere from 500-600mg. So if you're new to NPP, you could pin 50mg every day or 100mg every two days. As mentioned earlier, injecting NPP every 3 days is the absolute maximum you want to wait; but most guys will at least inject every 2 days for best results.<br />
<br />
14. You can run Shorter Cycles with this Drug<br />
<br />
Given that nandrolone phenylpropionate acts much faster than deca, it's great for running shorter cycles with. You can do a solid NPP cycle in as little as 6-8 weeks, which is good for those wanting fast gains without staying on gear forever. Contrast this to Deca Durabolin, where, due to the fact that it doesn't kick in for 4-5 weeks, the minimum recommended run time is 10-12 weeks. So while NPP might require far more pins than its nandrolone cousin, you won't have to use it as long either.<br />
<br />
15. You won't need an Oral Kickstarter with an NPP Cycle<br />
<br />
Oral steroids are often used as kickstarters with cycles involving long-ester injectables so that bodybuilders can get quick gains while waiting for the injectable to kick in. But what's great about nandrolone phenylpropionate is that you don't need to use an oral kickstarter to get fast gains. As mentioned earlier, NPP helps produce muscle gains within 2 weeks, meaning it's fast enough that there's no need to kick-start your cycle with Dianabol or another quick-acting oral steroid.<br />
<br />
16. Testosterone is usually run with NPP to keep Libido High<br />
<br />
Nandrolone phenylpropionate can have a very negative impact on your libido, which we'll discuss in the side effects section. And due to this potential problem, many bodybuilders like to run NPP alongside testosterone. Not only does this enhance your gains on a cycle, but it also keeps your libido going strong. There's some debate on the ratio of NPP vs. testosterone that you should run; however, a typical ratio is 5:4 in favor of testosterone. So if you run 400mg of NPP per week, you'd dose 500mg of testosterone each week.<br />
<br />
17. Here's a Sample NPP Cycle<br />
<br />
There's certainly no one-size-fits-all cycle for nandrolone phenylpropionate. It's popular to match up the NPP steroid with a long-ester injectable so that you get quicker results. However, some bodybuilders also like to run two short-ester injectables together as well. Such is the case in the following cycle I'm going to share with you, where the OP asks if they should inject 100mg of NPP every day, while being told that this is too much. They are instead advised only run 400mg of NPP per week and inject every other day. Below you can see what their final cycle looks like based on the advice given by everybody:<br />
Ancillaries: HCG (250iu x2 per week), Caber (0.25mg x2 per week), Arimidex (0.25mg EOD)<br />
<br />
PCT: Clomid<br />
