Apart from getting a bloodwork done how can u know if ur shut off or not? I mean if u feel all right, have no sexual dysfunctions and ur nuts have partly recovered... Ofcourse it is easy to say if u r lethargic or have some of the real obvious symptoms.. My sperm is very clear compared to what it was.. It is still white but not as thick as b4 (not nearly) I bet that was real interesting info.. HAHAHAHAHAHAHAH
