I have been taking elitropin green tops at 2iu 5 on 2 off for about 8 weeks.. started getting awkward soreness, mostly in my knees and hips, about a week ago. Is it possible that my growth plates aren't closed at the age of 25? I am already 6' 2", and have been growing pretty steadily since high school (graduated as a senior exactly at 6' tall) but I figured I was done.
