1/2 cycle recovery help !!

i did 1/2 cycle of liqua tech t-400 , reason why i stopped because im only 18 years old and people have told me i need to stop right now because my body wont stop growing until im 22, i need to stop changing my body's chemicals. I did, the 1/2 cycle lasted a month, i did 1 cc / week, i was wondering how long will take my body to get to it's normal lvl of hormones without any drugs. i know what to do for a normal PCT and all the drugs i need, but i was wondering if thats just nessary at all for the lil amount of test i did? thanks alot for all your help!
