Very interesting. Can you develop more? I tried to find some informations about HGH and whether it can be detected or not.
According to WADA website, HGH tests are reliable.
http://www.wada-ama.org/en/Science-Medicine/Science-topics/Q-A-hGH/
well
athletes take HGH, that is to say that it's the same hormone that we have naturally in our body (if it is legit HGH)
http://www.somatropin.net/hgh-brands.htm
they are really easy to get
since it's real HGH, you can detect it, but not prove it wasn't your naturally produced HGH
every lawyer will say (and he will be right) that a single measure of HGH means nothing
to really know if the person has abnormal level of HGH you have to do it in an hospital, during 24 hours, the patient being in a bed
why?
because HGH secretion is around 0 most of the day, with small peaks that appears randomly, and then the biggest peaks are at night, 1h30 after we fall asleep
http://www.ironmagazine.com/images/gh1.gif
this is an example of HGH secretion during a day
if you measure during a peak, the test will be positive, and if you measure outside a peak, the test will be negative
so a single measure means nothing
then, a lot of factors can create a peak of GH, like glycemy
so you have to do test to see how the body responds to the variations of glycemy
ect ect
an athlete can say for example that he had hyperglycemy, so it's logical that he had a peak of HGH at the moment of the dosage of HGH
HGH dosage is very complicated, very hard to do, and a single measurement means nothing
WADA tries to tell you the sport is clean , so they tell you the test works
yes, it works, but it means nothing, and every lawyer will tell it
when you will hear about a positive control to HGH, that will mean that the athlete tested positive, and that he admitted using HGH, or that they found proof that he bought HGH
other axample of HGH measurement:

(the graph on the left)
from wikipedia:
" A single value of the growth hormone (GH) is not useful in view of its pulsatality (levels in the blood vary greatly even in healthy individuals)"
"Frequent blood sampling with serum GH measurement shows that in normal subjects (left panel) GH can fluctuate between undetectable levels (most of the time) and peaks of up to 30 μg/l (90 mIU/l), owing to the episodic nature of GH secretion"
