considered first cycle or not?

my doctor put me on 200/mg of testosterone which was looked like 1/8 of the bottle full each shot, 6 bottles for 6 months 1 shot a month. i did it for personal reasons and it worked



i started at the age of 19 and now i am 20 took my last one last month





now my question is should i have been taking something with it, and should i pct? i feel like my hormones have changed too



thanks
