What is the half life of deca durabolin. Some websites say 6 days while some other say 9 -14 days?
6 days is what I've come across most often in my reading.
15 days. NPP is the shorter ester.
Most literature supports the 6 day half life of Deca Durabolin.
According to William Llewellyn the half-life of Deca Durabolin is 6 days:
"We can look at the half-life of injectable compounds in two ways. The first is the half-life for the release of the steroid from the injection site. This is usually measured in days with most commercial steroid preparations. In fact the total active lifespan of most oil-based esterified injectables is measured in weeks, sometimes several weeks. The second measure is to look at its half-life in open blood circulation. This is more a figure for personal interest sake than any practical application however, as the only relevant measure to the user is its release half-life. In any event, we can look at a human injection study with nandrolone decanoate (Deca) and see some pretty accurate figures on both measures (4). First we find that Deca exhibits a mean half-life of 6 days for the release of steroid from the injection site. You can see why people say that Deca can technically be active for as long as a month after injection. Next we find a half-live of about 4 hours for the hydrolysis of serum nandrolone decanoate to free nandrolone, and the total distribution and metabolism of nandrolone. The half-life for simply the removal of the decanoate ester was about an hour or less. Provided in the chart below as well are the relative half-lives of nandrolone and two other esters of it from intramuscular injection depot (5)."

thanks guys

Do some research on the decanoate ester and you will understand. Half life is not 6 days. It's sister compound, nandrolone phenylpropionate (NPP) is the shorter ester with a half life of 4.5 days.
