The answer is yes:
"The drug known as nandrolone (also known commercially as
Deca-Durabolin)... is an anabolic steroid (a muscle-building chemical)
which occurs naturally in the human body, but only in tiny
quantities... what is detected in the drug tests is the metabolism
product of this molecule, called 19-norandrosterone, which is excreted
from the body in urine, making it easy to obtain samples. A limit of 2
ng per ml of urine (set by the International Olympic Committee) is the
maximum concentration thought possible to occur in human body by
'natural means'... some samples given by athletes have shown levels
up to 100 times higher than this"
However, the test for this steroid is controversial. A number of well
known athletes were banned for showing positive in the test: "...
Linford Christie, Mark Richardson and Dougie Walker (all well known
British sprinters), Merlene Ottey (the Jamaican former 200 m world
champion), and Dieter Baumann (the German 500 m runner). After
protesting their innocence, all were subsequently cleared by their
national athletics organisations, although the International Amateur
Athletics Federation fueled the controversy further by overturning the
reinstatement of Christie and Walker."
One theory is that the combination of heavy training and the use of
supplements such as protein shakes or creatinine can cause a positive
result, and that this is somehow linked to the dehydration that can
result with heavy training.
Also, some Portuguese scientists have shown that people who eat pork
from non-castrated animals can also test positive, due to the high
levels of nandrolone found in the tissues of these animals. Eating 300
grams (just over 10 ounces) of liver from a non-castrated pig is
sufficient to make this happen.
