Nandralone-Phenylpropionate
This substance is very similar to the more common and well-known Deca Durabolin with main ingredient nandralone decanoate. The main difference between the two is the ester attached to the nandralone compound. Deca 100 Fast has a shorter phenylpriopionate attached than the more popular long acting decanoate.
Deca Durabolin releases from the site of injection over a 2 to 3 weeks period. Deca 100 Fast releases from the injection site and lasts about a week in the system. Deca 100 Fast is therefore best when being injected every 2 to 3 days to keep the levels in the system level. Apart from the time these two substances releases and last in the system Deca Durabolin and Deca 100 Fast are virtually interchangeable.
Nandralone phenylpropionate shows a sharp increase in blood serum levels of the free form of nandralone within 24 to 48 hours from the time of injection. Because of this sharp increase and quick release of nandralone this product is sometimes preferred to the longer acting version. After athletes compete and they battle with joint pain they prefer this substance because the longer acting version will take to long to kick in.
