When I was 17 I did 500mg sust and 65mg d-bol a day,that's right,it isn't a typo.65mg d-bol a day for 4weeks.
No clomid or nothing(very stupid) I lost most of my gains but my balls came back just fine. Took about 2 months,but they came back with no therapy.
I think when you are younger,your HPTA will come back faster.
I don't think andro will even affect your HPTA much as so little is absorbed in pill form,unless you injected.
By the way,I recommend KNOW ONE to use 65mg d-bol a day at 17,that was just plain retarded!
