NPP is one of the most beneficial anabolic steroids to ever hit the market. The benefits of this steroid can easily be seen in both therapeutic and performance based circles. In a medical setting, along with testosterone this is one of the most important anabolic steroids we have, and the advantages it can provide run extremely deep. While tremendous for medicinal purposes, NPP is also a premier lean mass promoting anabolic steroid. There are very few anabolic steroids that can pack on quality mass along side a high threshold of toleration like NPP. It is also one of the best steroids for athletic enhancement due to the recovery and endurance enhancement it can provide.
NPP is a potent anabolic, slightly more anabolic than testosterone. However, its androgenic nature is far less than testosterone, which makes NPP far more tolerable for many men compared to testosterone. Both hormones should fall in the tolerable category, but the lessened androgenicity gives Nandrolone a slight advantage. This advantage can also be seen when examining its estrogenic activity.
For the off-season individual looking to add large amounts of lean mass, NPP is an excellent steroid to choose. While the overall gains will still come slower compared to many steroids, the quality will be just that, quality. Water retention is possible, but should be extremely easy to control for most men. Significant and substantial amounts of lean tissue should be obtainable with this steroid, but it will only occur with enough calories in your diet. You must consume enough calories to support growth, and this will normally only require a few hundred calories per day above maintenance. Due to this necessary caloric surplus, this will typically promote body fat gain during the off-season, it’s inevitable, but the use of NPP should limit it. Nandrolone Phenylpropionate has been shown to have a very strong metabolic enhancing effect.
As bulking is a primary purpose of use, many rarely think of NPP as part of a cutting cycle, but it can serve a purpose. This steroid will greatly protect lean muscle mass during a necessary caloric restriction. Remember, to lose body fat you must burn more calories than you consume, and this can lead to lean tissue loss. NPP supplementation will prevent this. During the dieting phase, many also choose to use NPP for the recovery, endurance and relief it can provide.
The final point of use that sums up the effects of NPP is direct athletic enhancement. NPP does have the ability to increase strength, but it’s not what we’d consider a premier strength increasing steroid. Where this steroid shines in athletics is once again in its promotion or enhancement of muscular endurance, recovery and relief.
NPP is a faster acting Nandrolone compound and will require more frequent injections.
For the purpose of performance enhancement, 100mg per week will provide some nice therapeutic relief, but most men will find 200mg per week to be the low end dose. 200mg per week will improve recovery, ease joint pain and provide a moderate anabolic boost. Most men will find they can tolerate 300-400mg per week very well. Such doses are very common for the purpose of building lean muscle mass. More can be used, but this will increase the risk of adverse effects. Regardless of the dose, the total dosing should be split into a minimum of two injections per week. Three injections per week will prove to be very efficient with some choosing an every other day injection schedule, especially when supplementing with higher doses. The total duration of use will normally fall in the 8-12 week range.
Women who use NPP for the purpose of performance enhancement will find 50mg per week administered in one injection to be as far as they will want to take it. Total use will normally fall in the 4-6 week range and should not surpass 6 weeks if virilization is to be avoided. Many women will find choosing steroids with even less androgenic activity to be the best way to go, such as steroids like Oxandrolone and Methenolone Enanthate.
NPP side effects
NPP has a low tendency for estrogen conversion, estimated to be only about 20% of that seen with testosterone. This is because while the liver can convert nandrolone to estradiol, in other more active sites of steroid aromatization such as adipose tissue nandrolone is far less open to this process.
The side effects associated with progesterone are similar to those of estrogen, including negative feedback inhibition of testosterone production and enhanced rate of fat storage.
Although classified as an anabolic steroid, androgenic side effects are still possible with this substance, especially with higher doses. This may include bouts of oily skin, acne, and body / facial hair growth. Anabolic / androgenic steroids may also aggravate male pattern hair loss.
NPP can have a negative impact on HDL cholesterol (good cholesterol) and it can be somewhat more significant than testosterone. This negative effect may be exasperated by the use of an AI. It is more than possible to use NPP without cholesterol issues or cardiovascular incident, but a healthy lifestyle is imperative. Regular cardiovascular activity is important as is a cholesterol friendly lifestyle.
The use of NPP will suppress natural testosterone production. As with all Nandrolone compounds, one injection will suppress nearly if not all your natural testosterone production. Your genetics will not prevent this and it is something that’s completely unavoidable with use. Because of this fact, it is imperative that all men who use this steroid do so in conjunction with some form of exogenous testosterone – be it Testosterone Cypionate, Testosterone Enanthate or Testosterone Propionate. This will prevent the individual from falling into a low testosterone condition, which comes with very undesirable symptoms.
on my 8th week now of a sustanon and npp cycle and its my best cycle ever, this has me looking shredded and its only my 2nd cycle. thank you tas i will be be back again soon for my third
