In 1983 Nandrolone was approved by the FDA for the treatment of variety of medical conditions including metastatic breast cancer in woman. This drug is also effective for increasing Haemoglobin and red blood cell mass so therefore effective in treatment of anemia of the kidneys. Nandrolone has even been used as a female contraceptive and treatment of osteoporosis after menopause. Deca-Durabolin/NPP active compound Nandrolone is a natural occurring hormone in our body (19-nortestosterone), hence the close resemblance to testosterone except an absence of a carbon atom in the 19th position and has an anabolic to androgenic ratio of 125:37. Among the bodybuilding community after a recent survey Nandrolone was named the most widely used anabolic steroid on the market.

Nandrolone has been shown to interact with both the androgen and progesterone receptors as well as increase IGF-1 levels in the body. This drug is also highly suppressive when supraphysiologic doses are used; some people say a single shot of Deca can completely supress natural testosterone production. It is also recommended to use an Aromatase Inhibitor compound like Anastrozolone (Arimidex) and even included prolactin lowering drugs like Dostinex or Parlodel (Bromocriptine) to your cycles or during PCT. It has been reported that elevated Prolactin levels may affect how you find your recovery when doing your Post Cycle Therapy and elevated Prolactin levels caused by increased progesterone and estrogen can cause side effects like erectile dysfunction and I am guessing that is where the name deca dick came from. Do not self-medicate Prolactin Lowering drugs without actually having blood tests done; they come with their own list of side effects.

Nandrolone is a steroid that is administrated intramuscular and when using the long ester version weekly shots would be the best protocol to follow. Although there used to be an oral version of this drug, this no longer exists on the market. Deca-Durabolin gives its users a new foundation of strength with nice quality muscle growth, Deca stacked with Sustanon is actually called your bread and butter cycle. And with that said Deca is very rarely used on its own and is commonly advised to be cycled with Testosterone and extend the Testosterone 2 weeks after the discontinued use of Nandrolone.

One of the reasons people are starting to find favour with NNP is that it is quick acting and gets out of the body allot quicker, whereas the long ester version takes around 4 weeks to kick in and another 4 weeks to get out of your system before an effective PCT can be administrated, that is close on 8 weeks of your cycle that is wasted. Reported doses are around the 200mg to 600mg per week based on the sum of 2mg Deca-Durabolin per pound of bodyweight, however I would not advise anything under 400mg if you are looking to build muscle. Common doses for Intermediate to Advance users are around 500mg per week upward. Based on those figures you are looking in the region of 1 to 2ml per week of Precision Gear Works (PGW) Deca 350. Or just less than 1ml EOD (every other day) of their short acting version of the drug called Nandrolone Phenyl Propionate (NPP) dosed at 150mg per ml. The reason why it is advised to take less of the faster acting ester when compared to the same drug with a long acting ester is that the short esters release more of the hormone on a mg to mg basis.

Just like Deca, NPP can be detected in the urine for well over a year. Yes our bodies naturally produce 19-nortestosterone, so users have reported false positives in their doping tests. Another quick note, doses over 600mg a week mark do not necessarily pose greater anabolic effects, so in saying that a weekly dose of 600mg compared to a 800/1000mg may show no improved anabolic effect and you just asking for more side effects and marginal difference in results. So in this case more is not always better and unless you going to be doing regular blood tests throughout your cycle I would take this advice and keep a moderate yet extended cycle period.
