Because either way I was going to cycle and I've noticed that if your under 21 you dont get an answer - even if I waited until I was 21 (which is soon) I still probably wouldnt have gotten solid answers

By putting my age as 24 I got the correct answers therefore I could cycle correctly. However my BF% was a typo I'll admit that, should be ~20% not ~10%.
Thanks higherdesire, will look into those!
