The problem is the ones NOT on their radar screen.

OK, but . . . [hang in there, I think I'm closing in on SOMETHING here!] aren't there other things, like HGH, that are used legitimately by medicine, but cannot be accounted for by the current drug testing technology?

Well you already mentioned EPO. I'd have to do some research to find others but as I said above I think you are overestimating the number of useful things that are out there.

Viagra? It wouldn't surprise me, it seems to be a one drug fits all type of thing. Is it dectable? I don't know. Is it on the banned list? I don't know. Should it be on the banned list? I don't know.

See how ignorant I am :lol:

taffy

iirc the problem with HGH was not it's detectability ( it's very easy to detect ), but that the normal range was so huge, that it's was virtually impossible to really assign a cut-off line as being definite doping ( similar thing with testo, where they didn't get anywhere with absolute testo level, but fortunately that had a closely-linked associate, epitesto which went up in tandem with normal human production of testo, so they figured on 4:1 as being limit of natural production ( body normally produces linked amount of these in something like a 1:1 ratio - external testo won't put up epi-testo, so ratio starts shooting up )

someone will have to look up HGH range, but it was something like 100 - 900 units/cc & a doper coud have it near the 900 & you still coudn't accuse them of doping, as he/she coud just turn around & say that's still in the normal range & normal body production

anyhows, all the HGH nowdays is synthetically derived & they look for the synthetic part ( same as with EPO test )

the main reason they can test for these nowdays is because they are now all synthetically derived

http://en.wikipedia.org/wiki/Growth_hormone

Most of the physiologically important secretion occurs as several large pulses or peaks of GH release each day. The plasma concentration of GH during these peaks may range from 5 to 35 ng/mL or more. Peaks typically last from 10 to 30 minutes before returning to basal levels. The largest and most predictable of these GH peaks occurs about an hour after onset of sleep.[4] Otherwise there is wide variation between days and individuals. Between the peaks, basal GH levels are low, usually less than 3 ng/mL for most of the day and night


( the underlined bit is the basis of the ole wives tale saying that if children don't get enough sleep at night, they won't grow up to big & strong )

in the past, an athlete coud just claim that the dope test was done when they had a surge of HGH production

Does this mean that if I do my weight work just before bed, I'll benefit more? :twisted:
