So, I’m 17. I started training with weights in Dec 2013 with absolutely no knowlege/experiece. I got my squat from 80 to now 145lbs. I can deadlift 160lbs easily. Bench press on and off since my bench is broke. So would you say my beginner gains are gone and I need to use creatine? I am going to buy some whey soon. I am also trying to gain weight. I’m 147 right now. Trying to be 155 by mid-June. Any suggestions to add on to this. I did 5×5 training for almost 10 weeks a few months ago (got me to that heavy squat lol 😉 )
Another useful dynamic test involves measuring the response to exogenous steroids; individuals with AIS show a decreased response in serum sex hormone binding globulin (SHBG) after a short term administration of anabolic steroids.   Two studies   indicate that measuring the response in SHBG after the administration of stanozolol could help to differentiate individuals with PAIS from those with other causes of ambiguous genitalia, although the response in individuals with predominantly male phenotypes overlaps somewhat with the response in normal males.
Genetic females (46,XX karyotype) have two X chromosomes, thus have two AR genes. A mutation in one (but not both) results in a minimally affected, fertile, female carrier. Some carriers have been noted to have slightly reduced body hair, delayed puberty, and/or tall stature, presumably due to skewed X-inactivation.   A female carrier will pass the affected AR gene to her children 50% of the time. If the affected child is a genetic female, she, too, will be a carrier. An affected 46,XY child will have AIS.
