ur answer right there
and for the 2nd one... preggo tests test HCG in the blood, so if u r using some HCG, you can use a preggo test and it would return positive... or if ur worried that ur GH is HCG, then put it on a test, and it should return negative
"Pregnancy tests look for a special hormone in the urine or blood that is only there when a woman is pregnant. This hormone, human chorionic gonadotropin (hCG), can also be called the pregnancy hormone"
HCG in males increases LH, which will help increase the size of the boys while on cycle or pct
