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.
