I think the answer is what are you trying to accomplish? If it is getting a little more edge, keeping your body repaired and keeping the years off that is the right idea. Maybe 2 to 4 ius a day but I agree with unvocrew, any hint of cancer in the family or anywhere or tumors means get checked. But yes that is a good method and make an eval in around 6 to 9 months. Also make sure to not take it at night because it interferes with the regular body cycles.
