i will repeat what i wrote to the last dude. if you can NOT gain by diet and training at 17 or 18 ect. YOU WILL NOT GAIN ANYTHING FROM TEST OR DBOL THAT YOU WILL KEEP AFTER PCT. PERIOD. they are NOT magic. you have plenty of test at your age. increasing your test 4x is a very poor risk/reward. please post pics before and 6 weeks after pct so you can save the next guy from doing the same.
another thing. every thing you've asked is here. already written and MORE. it's free. no cost. read, read, read, read... you just might learn what i'm saying is 100% tru. NOT TRYING TO BASH YOU. trying to educate you. ultimately what you do is your call, not your dad.
