npp steroid + (1)
Durabolin, better known among bodybuilders as Nandrolone Phenylpropionate, or simply NPP, is also a close relative of Deca Durabolin. However, since for many years NPP steroid was very difficult to obtain and had an inconvenient dosage, few people used it. However, in recent years, clandestine pharmaceutical companies have begun to produce Durabolin in a wide variety of dosages, thereby making it more accessible and convenient to use. Therefore, this steroid deserves the closest attention, as NPP is more than just Deca Durabolin with another ester.
NPP steroid history
NPP steroid and Deca have one common active substance – nandrolone, which very much unites the history of their origin. Few people know, but nandrolone as such was developed in 1957, and initially the most popular version was nandrolone with phenylpropionate ether. However, in 1962, a decanoate ester version came on the market and was named Deca Durabolin. Due to some significant advantages in ease of use, it has become more popular than nandrolone phenylpropionate. As a result, Deca has become one of the most widely used steroids of all time, while NPP has become a rare anabolic androgenic steroid (AAS) that few people know exists.
Be that as it may, clandestine laboratories have eliminated one of the biggest drawbacks of NPP, as Durabolin has become available in a greater variety of dosages. This has allowed nandrolone phenylpropionate to find its place in modern bodybuilding, as the shorter ester has its advantages and is getting more and more popular every day.
Description
The anabolic steroid nandrolone belongs to the 19-nortestosterone family. Moreover, it is very similar to testosterone, with the only difference being that it lacks one carbon at the 19th position. From there comes the name of the family of steroids associated with nandrolone, which are also called 19-nor substances.
As a consequence of this structural difference, unlike testosterone, which is converted to dihydrotestosterone (DHT) by the enzyme 5-alpha reductase, nandrolone is converted to the weaker androgen, dehydronandrolone. Because of this, the stronger DHT cannot bind to androgen receptors, which causes a noticeable suppression of natural testosterone production. Therefore, it is always recommended to take nandrolone in combination with testosterone-based steroids.
NPP vs. Deca Durabolin
Both steroids are based on the same active substance – nandrolone. However, although they share most of the advantages and disadvantages of nandrolone, they have different esters, which creates some differences between them. Durabolin has a phenylpropionate ester attached, which has a very short duration of action, while Deca Durabolin has a much longer-acting decanoate ester. Despite the fact that, in theory, esters can only influence the rate of release of the active substance, these two steroids have more fundamental differences in action, which give different possibilities for use.
A short broadcast of NPP is both an advantage and a disadvantage. On the one hand, due to the shorter half-life, more frequent injections are required compared to deca – 2-3 injections per week versus 1 injection per week. On the other hand, the short half-life makes NPP a faster acting steroid than Deca, allowing for shorter cycles with the same results. For example, an average deca course will last 14-16 weeks, and a longer recovery period will be required after such a course. While with NPP, 10 weeks is enough, which allows you to reduce the recovery time.
Further, the longer deck ester delays the action of this steroid, creating the need for an additional oral steroid to act as a pusher. In turn, the NPP acts much faster, which allows you to use a smaller amount of AAS during the cycle, since there is no need for “pushers”. This also means that NPP leaves the body much faster than Deca; according to some studies, it is flushed out of the body twice as fast.
Nandrolone phenylpropionate Side effects
Nandrolone, especially phenylpropionate, is known to be a steroid with relatively mild side effects. As mentioned before, estrogenic side effects are rare and easy to manage. In terms of androgenic activity, Durabolin has fewer androgenic side effects (oily skin, body/facial hair growth, baldness, etc.) compared to other AAS.
At the same time, despite a moderate rate of conversion to estrogen, NPP may have a suppressive effect on the production of endogenous testosterone. Therefore, it is recommended to take drugs such as HCGenerate ES and Clomid at the end of the course and during post-cycle therapy (PCT). They will stimulate the natural production of testosterone and help the body recover faster.
Nandrolone phenylpropionate dosage and application
The average dose of NPP is 300 mg per week. Therefore, it can be used either twice a week at 150 mg or three times a week at 100 mg. However, there is not much difference between the two approaches and it all comes down to personal taste and preference. As for the duration of the course, thanks to the short broadcast, 10 weeks will be enough to achieve good results.
In terms of combination, most often Durabolin is combined with steroids, which also have short esters, such as testosterone propionate and boldenone acetate. It also combines well with oral steroids such as winstrol and anavar. All these steroids are used in short courses, which fits perfectly with the concept of a short course of taking NPP. But still, Durabolin can also be used in longer cycles, because its mild side effects allow it to be done without compromising health.
Nandrolone phenylpropionate builds muscle mass slowly but very steadily. Due to its ability to retain nitrogen, it gives a very high quality and sinewy muscles, which is also less prone to the rollback phenomenon. This amazing quality, coupled with reduced water retention, makes this steroid one of the best choices for cutting and preparing for competition. It is also worth noting that Deca Durabolin is mainly used in the mass gain phases.
