Reading your post I was thinking you were possibly in your 20's because you said you started AAS at 18. Then, you admit that you're STILL 18. WTF

Way too young but damage is done. Your balls may never recover. You are very young and esp. running such high amounts for such a long time. It is likely you may never recover.

Do as Capebuffalo said and start it today. You don't want a lifetime of E.D. and sexual side effects. Your HPTA is pretty much at its peak right now and shutting it down is just stupid.
