you don't look like you need to lose 30 pounds in your pic. what is the deal? your body fat is in the low to mid teens which is fine. and you have good muscle mass on you. no way you are 18%, that scale you are using sounds like its one of those that you stand on and those aren't accurate at all. in fact I will flat out and tell you that you are 12-13% body fat tops.
as far as what AAS to use now that we have found out that scale you were using was bullshit, now what are your revised goals?
