do people realize how hard it is to detect HGH?

i heard alot of people on NSB saying that the only reason for the blood testing is because urine test cant detect HGH. which is correct but i dont think people realize how hard it really is to detect HGH. here is an interesting article i found: What is Human Growth Hormone? Human Growth Hormone (HGH or hGH) is the most abundant hormone produced by the pituitary gland (pituitary is one of the endocrine glands). The pituitary gland is located in the center of the brain. HGH is also a very complex hormone. It is made up of 191 amino acids - making it fairly large for a hormone. In fact, it is the largest protein created by the Pituitary gland. GH has a half-life in the blood of approximately 17 to 45 minutes. Because of this, detecting GH in a drug screen is very hard. HGH secretion reaches its peak in the body during adolescence. This makes sense because HGH helps stimulate our body to grow. But, HGH secretion does not stop after adolescence. Our body continue to produce HGH usually in short bursts during deep sleep, intense exercise and when the hormone insulin is low. Growth Hormone is known to be critical for tissue repair, muscle growth, healing, brain function, physical and mental health, bone strength, energy and metabolism. In short, it is very important to just about every aspect of our life! http://www.rippednaturally.com/bodybuilding_hgh_human_growth_hormone.html
