pct is post cycle therapy- one of the forums on here talks about it. Do ALOT of research b4 doing anything- these guys know what they're talking about. PCT is "what are you gonna take after your cycle is done to get you back to normal?" Cuzyou wont be normal- your test after a few weeks off will be close to nil. Research pct stuff for a long time and ask lots of questions- youre 19... workout, eat, grow, dont need test yet- when you cant grow anymore in a few years then use the test to get bigger. Or d what ever the hell you want but dont cry later- good luck.
