i cant believe you posted about taking them while you were on the entire time for 3 weeks. i started when i was even younger than you. it was a month before i turned 18. i now stand at like 5'6" i think maybe 5'5" honestly. ive damaged my body using it that young. im almost 25 now so it doesnt matter if i take anything now or not, ive already done the damage. im going to be short forever. if i were you, i would get off immediately. what that guy said about being big for a short while but small for the rest of your life wasn't a joke.
