I thought HGH was essentially a synthetic testosterone and as such was indistinguishable from natural testosterone. Anyone know how they eliminated false positives? Just curious.

HGH != Testosterone

SanAngeloState

HGH isn't testosterone. It's "human growth hormone" which is secreted by the pituitary gland or whatever. Not sure how they tell if you are on it or not, as in how to tell if you are supplementing your natural HGH.

People can take testosterone or testosterone like substances. Those are referred to as "anabolic steroids"....if you take synthetic testosterone (which is the same chemically as the real stuff), I'm not sure how they tell. I would guess they measure other things in the blood which indicate that your own production is "shut down", due to supplementation.

Rugby League player Terry Newton was the first (and only?) sportsman to test positive for HGH:
Terry Newton handed two-year ban after positive test for hGH in landmark case - Times Online

There's some details in the article about how they came to the positive result etc.

can't wait to see who gets popped for hgh

FALSE

are you serious???? look it up on google my goodness. Did you even know what the acronym HGH is?



educate yourself on this matter...

anabolic steroids ='s synthetic testosterone.

HGH is merely a hormone (Human Growth Hormone.)

Heavy lifting elevates both levels. deadlifts and squats are these guys best friends. Lift Big Eat Big Sleep Big GET BIG

do look HGH up and Testosterone to self educate- 2 different things

Your test levels would be higher and your T/E ratio would be off

Actually, it's not, in two very subtle ways:

(1) There's an isomer of testosterone (T) called epitestosterone (E); normally your body produces both in equal amounts. [Although it's not a perfect analogy in this particular case, consider a pair of gloves; the left-handed glove and right-handed glove are mirror images of one another, but you can't use one in place of the other. T and E are nearly identical, but the body can't use E; it's just an "artifact" of how the body produces T in the first place.]

Synthetic T, though, usually has no E, so if the T/E ratio is much greater than 1:1, that's taken as evidence of doping (it's how Floyd Landis got caught). [Because they usually test for the ratio, overly elevated levels of "E" are also considered a doping offense because they can mask elevated levels of "T".]

(2) There's more than one isotope of carbon; natural T tends to have a slightly higher percentage of the heavier isotope (carbon-13) than synthetic T because humans don't make T the same way that synthetic T is made. . . . so if the carbon ratio in T is out of whack relative to the carbon ratio for other hormones, than that's evidence of doping, too.
