Human Growth Hormone is a naturally occurring peptide, secreted by the pituitary gland, usually during sleep or after some anabolic training.
If one uses injectable HGH, it rapidly metabolizes into IGF and other subhormones which then assist the body in rapid recovery. It's not an analog/derivative of testosterone which is easy to test for. The HGH spike disappears in the system, within an hour or so. And even its subsequent metabolites don't have lengthy residence periods.
Thus, if one isn't routinely injecting on a regular basis and let's say, juices weekly, chances are, it won't be detected. In addition to injections, an athlete can also shallow 2-3 grams of certain Amino Acids like Arginine/Ornithine/Lysine on an empty stomach daily, and also get a base line IGF increase without it being a case of doping. Taking Amino Acids doesn't violate any rules.
Heard that one at the gym, about the amino's.....Thanks..! TP..for your effort..!
What I think it means is that an HGH scandal is highly unlikely for the NBA, unless players are so lackadaisical, that they inject all the time. The MLB guys, however, took steroids, which in their case were analogs of testosterone. Clearly, there's no way to hide that and for the most part, they were easy to bust. In order to bust someone for HGH, you have to clearly show a marked deviation from baseline hormone levels. Sorry, but with a daily amino acids regimen, that'll immediately turn into a "he says, she says" type of argument instead of an indictment.
