wada has 2 blood methods that have been developed for testing hgh. the most common test is looking for a skewed ratio of 20k to 22k dalton isoform hgh. this test can be circumvented by using a ghrp or ghrp +ghrh combo. In the study you see the hgh dose was 7.5iu equivalent of hgh. This is much more hgh than your body can use effectively at one time because the somatotropes will be all filled. This causes 2 problems, your body will naturally inhibit its own gh production (therefore raising 22k levels further), and elevated GH will take longer to leave the system since blood levels will gradually decline over a day or so.
The second hgh test will determine elevations of igf1 and pn3p (collagen formation). Massive elevations of hgh will cause massive blood serum igf elevations over the next few days after a dose. In this system an athlete could fail days after the final dose and doping authorities say even possibly weeks from pn3p. The issue is that this test is expensive and first used at the paralympic games in 2012 qand got a couple lifters. It also can be circumvented
High blood hgh will cause elevations of blood igf and puts you at risk for failing. taking smaller more frequent doses of gh 1-2iu will allow the somatoropes to refresh quickly and keep blood igf1 from skyrocketing for an extended period due to hgh elevations. so instead of 5iu at a time try 5iu split in 3 hits and if you want better coverage in case of door knockers, dose ghrp+ghrh combo before a small hgh hit. this will let you elevate 20kda hgh a bit and hide that short gh pulse.
Muscular hgh levels are correlated to increase performance, elevated serum levels have not been. our bodies spurt gh in small amounts frequently during puberty, it has to be a better way and the body has to have good reason. if not we would just spurt out everything from the pituitary at once each day.
GH testing is basically going to easily catch those who just dosed prior to the test without ghrp, dosed too much at once.
intravenous dosing would be the easiest solution but not necessary unless using larger doses that are needed to clear more quickly.
Ghrp2 can be detected in urine for 4.5hours but I have yet to hear of any positives world wide
