This may be a stupid question but oh well..my natural test level is within the level it should be at, if I stay on test would I be damaging my endo system? Reason why I am asking, is because I find it helps working out and weight loss etc. I'm about to do a PCT, wish I don't have to, hate how I feel while my body kick starts the natural test. It makes me a zombie at work. What are the long term affects of staying on Test? Cancer? other issues?
