Here's a little HGH info for you taken from Barroso, Sc*****ch, and Rabin
"Detection of GH abuse in sport: Past, present and future". From the Journal of Growth Hormone & IGF Research Volume 19 Issue 4. Published May 2009.

"The development of hGH-specific methods for anti-doping purposes, however, has constituted a significant scientific and logistical challenge for the anti-doping authorities. Despite the availability of multiple assays for quantification of hGH for clinical and research purposes, all have proven unsuitable for anti-doping applications. The structural and biochemical similarities between rhGH and the major endogenous 22-kDa isoform, the pulsatile manner of hGH release and its short half-life in circulation, and the influence of exercise and nutrition on hGH plasma levels, among other factors, contribute to the difficulty of detecting the abuse of hGH as a doping agent [14] and [15]. Similarly, many of the currently available tests for some of the hGH-dependent markers (e.g. IGF-I) have proven to be unreliable for doping analyses, thereby requiring extensive validation studies of existing commercial assays or the application of novel approaches towards the development of well-characterised and accurate assays."
